DIY Onocoy Reference Station Setup Guide
In this guide, we’ll walk you through the process of setting up your own GPS Onocoy server using cost-effective hardware options and reliable GPS receivers. Whether you’re interested in enhancing the accuracy of your location-based applications, conducting precision surveys, or simply exploring the world of DIY technology, this guide provides step-by-step instructions to help you get started with creating your DIY Onocoy reference station.
What is Onocoy?: Advancing GNSS Correction Data
Onocoy is an innovative platform that harnesses GNSS devices and correction data to create a decentralized network for precise positioning and navigation. It offers users the opportunity to contribute to this network while earning rewards based on their data contributions.
Enhancing Your GNSS and RTK Setup
Onocoy offers a fresh perspective on GNSS stations. Beyond pinpoint accuracy, it’s about becoming part of a global network that benefits users worldwide. Discover the key considerations for setting up your station: from selecting the right equipment to optimizing antenna placement and ensuring reliable internet connectivity.
Contribution and Rewards
At its heart, Onocoy not only improves accuracy but also recognizes your contributions. Uncover how your role in enabling specific NTRIP messages and maintaining low latency translates into tangible rewards. Onocoy’s approach ensures a fair distribution of rewards through blockchain technology, providing transparency in recognition.
Understanding Onocoy’s GNSS Capabilities and Requirements.
Exploring the GNSS capabilities of Onocoy sheds light on the diverse channels and bands it supports. As a rule of thumb, a broader range of bands and constellations translates to enhanced rewards within the network. For an in-depth understanding, refer to the insights shared in section 4.2.1 of the whitepaper, which is accessible on LinkedIn here and soon on the official website.
Update rates, a crucial factor, cater differently to miners and RTK Rovers, who are the data consumers utilizing the Onocoy service. Miners find stability with a rate of 1Hz, ensuring steady data contribution. In contrast, higher update rates like 10Hz, 20Hz, or even 100Hz predominantly serve RTK Rovers’ needs for real-time precision.
Addressing the notion of minimum required position accuracy, Onocoy adopts a pragmatic approach. Straying from stringent demands, the system’s meticulous processing accurately determines device positions during validation steps, ensuring reliability without undue accuracy expectations.
Signal-to-Noise Ratio (SNR) and signal levels emerge as pivotal factors. SNR above 40 dBHz, preferably reaching around 45 dBHz, signifies optimal performance. Lower SNR values, stemming from factors like extended cables or antenna quality, can elevate code/carrier noise, potentially affecting measurement quality. Two fundamental principles guide this aspect:
- Ensuring an unobstructed 360-degree sky view for the antenna, ensuring unhindered signal access.
- Aiming for a secure and stable antenna mount to counteract vibrations and instability.
This comprehensive approach forms the bedrock of reliable and robust data contribution to the Onocoy network.

Ideal Setup Setup For Onocoy
For Onocoy, we recommend the following components for an optimal setup. This combination ensures high precision, versatility, and reliable performance.
This combination ensures a powerful computing platform with the Beelink U59 Mini PC, coupled with the high-precision positioning provided by the UM980 RTK GNSS USB Dongle and the reliable performance of the HARXON CSX627A Triple Band RTK Antenna. The recommended GNSS USB Dongle is our preferred choice for its exceptional precision and features, making it the ideal solution for Onocoy applications.
Below we’ve included other alternatives.
Recommended Hardware for Onocoy:
One of the following is required. We basically just need any efficient and low powered computer we can get our hands on that also runs Linux. Any Raspberry PI, Intel NUC, or similar will do. They don’t have to be all that powerful. However, we will recommend you have at least 32g-64g of flash-based storage (for longevity of the SSD). For this, we will be targeting a budget of around $50-$200 for compute hardware, but feel free to go higher if it suits your needs. Our power target is approximately 10w average.
Raspberry Pi and Pi Clones:
Hard to get ahold of these days but they are super low power and are quite customizable. For info on how to install Raspbian on your Raspberry PI.
Any Mini PC with Intel N5100 or similar:
For super low power Raspberry Pi equivalent but on x64 platform.
Ultra Low Power / Low Budget
Compute Notable Mentions
Older Raspberry Pi models (1, 2, 3) should be sufficient. But newer models should be significantly more efficient and allow you do run multiple low powered mining setups on a single device. This is why we recommend newer compute hardware.
Recommended GPS Receivers for DIY Onocoy Deployments
There are many receivers on the market but at a bare minimum it must support RTCM (Radio Technical Commission for Maritime Services) and ideally have the ability to be hooked up to an antenna outside of the install location with 360 degree unobstructed view of the sky.

We won’t go into the technical details of how to install an operating system here. However here are some great resources to get you started.
Raspbian:
Ubuntu:
- Install Ubuntu desktop
- Ubuntu Server - Basic installation
- Ubuntu Complete Beginner’s Guide: Download & Installing Ubuntu
Proper Onocoy Base Station Antenna Placement
Onocoy has published antenna placement requirements , but to summarize you should understand the following:
Optimal Location Selection: To optimize station placement,** choose a location at least 20 kilometers away from the nearest Onocoy station**. Stations located close to three or more others will receive reduced rewards. Utilize the Onocoy Explore function to easily check the distance to the nearest Onocoy station for any location.
Ideal Surroundings: Ensure that the antenna has an unobstructed 360-degree view of the sky, with no obstructions such as buildings, trees, or mountains above 10 degrees elevation. Limited sky visibility or signal multipath can result in scaled-down rewards. The antenna must be rigidly mounted to prevent movement exceeding 1-2 millimeters, as excessive vibrations or movement can lead to reward pausing.
Stable Internet Connection: Maintain a stable and permanent internet connection for the station. The required bandwidth is relatively low, typically around 1 kB/s, and no inbound traffic is necessary. There is no need to open ports on typical firewalls, as connections are established from inside-out.
Setting up the Onocoy Base Station and NTRIP Software
Once you’ve set up your device and properly placed your antenna , you can start configuring the required software.
For this section we assume some basic technical experience and that you have installed your operating system already as well as know how to get into the terminal.
- We need to create an account and get our credentials from the onocoy website . You will need to grab the server address, username, password, and port number from this step. Once it is completed, go to the reference station tab and grab the mount point, which we also need.
- Refer to the Onocoy documentation if you need help.
Install some base dependencies.
sudo apt install -y gpsd gpsd-dbg gpsd-clients gpsbabel minicom socat git make build-essential
Follow one of the Options Below. Either NTRIP Server or RTKLIB
Wait and Verify Your Station on the Onocoy Dashboard
- Visit the Onocoy Console Dashboard and check to see your device has finished it’s validation period. If it hasn’t check back later, it can take up to 3 days.
Profit?
- You can view the following Onocoy documentation to learn more.
Option 1: NTRIP Server
On your linux device download the ntripserver software.
git clone https://github.com/simeononsecurity/ntripserver.git cd ./ntripserver make
Identify the USB Source
lsusb
Ex.
Bus 00x Device 00x: ID xxxx:xxxx Prolific Technology, Inc. PL2303 Serial Port / Mobile Action MA-8910P
orBus xxx Device xxx: ID xxxx:xxxx U-Blox AG [u-blox 8]
Note: Some devices may show up as
ttyUSB0
,ttyACM0
, etc. You’ll have to look this up per your device. `ls /dev/ttyUSB*
Note: Minicom is a tool used to view the serial output of devices. To use it, you’ll need to read this guide on using minicom . If this sounds difficult to you, skip this step.
sudo minicom -D /dev/ttyUSB0
Now we get to configure the software
Note: The onocoy dashboard/explorer won’t provide you with the mountpoint information until they verify you can send them data. Omit the mountpoint details from this section until after you initially get past that window. Then test it again.
Test the configuration.
~/ntripserver/ntripserver -M 1 -i /dev/ttyUSB0 -b 921600 -O 1 -a servers.onocoy.com -p 2101 -m {{mountpointhere}} -n {{usernamehere}} -c {{passwordhere}}
Now that you confirmed it works. We need to create a service to have it restart on boot.
- Create a Service File:
sudo nano /etc/systemd/system/ntripserver.service
Remember to replace
/path/to/ntripserver
with the actual path to your ntripserver executable.[Unit] Description=NTRIP Server Service After=network.target Wants=network-online.target After=network-online.target [Service] ExecStart=/path/to/ntripserver -M 1 -i /dev/ttyUSB0 -b 921600 -O 1 -a servers.onocoy.com -p 2101 -m {{mountpointhere}} -n {{usernamehere}} -c {{passwordhere}} Restart=always RestartSec=120 # 2 minutes (in seconds) TimeoutStartSec=300 # Set a 5-minute timeout (adjust as needed) User=root [Install] WantedBy=default.target
- Enable and Start the Service:
sudo systemctl enable ntripserver.service sudo systemctl start ntripserver.service
- Check the Service Status:
sudo systemctl status ntripserver.service
ex.
ntripserver[815]: serial input: device = /dev/ttyUSB0, speed = 921600 systemd[1]: Started NTRIP Server Service. ntripserver[815]: caster output: host = xxx.xxx.xxx.xxx, port = 2101, mountpoint = Mount1, mode = http ntripserver[815]: transfering data ...
Option 2: RTKLIB
On your linux device install the rtklib software.
sudo apt-get update sudo apt-get -y install rtklib
Identify the USB Source
lsusb
Ex.
Bus 00x Device 00x: ID xxxx:xxxx Prolific Technology, Inc. PL2303 Serial Port / Mobile Action MA-8910P
orBus xxx Device xxx: ID xxxx:xxxx U-Blox AG [u-blox 8]
Note: Some devices may show up as
ttyUSB0
,ttyACM0
, etc. You’ll have to look this up per your device.ls /dev/ttyUSB*
sudo minicom -D /dev/ttyUSB0
Create a Rtkrcv.conf RTKLIB Configuration File
- Create the paths and conf file
sudo mkdir ~/rtklib/ sudo nano ~/rtklib/rtkrcv.conf
- Conf File Contents
Note: The onocoy dashboard/explorer won’t provide you with the mountpoint information until they verify you can send them data. Omit the mountpoint details from this section until after you initially get past that window. Then test it again.
[serial] port = /dev/ttyUSB0 bitrate = 921600 [ntrip] caster = servers.onocoy.com port = 2101 mountpoint = {{mountpointhere}} user = {{usernamehere}} passwd = {{passwordhere}} [output] format = rtcm3 path = /path/to/output/file.rtcm
- Test the RTKLIB config
rtkrcv -s -o ~/rtklib/rtkrcv.conf
Create the RTKLIB Service
Create the Service Unit File
bash sudo nano /etc/systemd/system/rtklib.service
Add the Service Configuration ```toml [Unit] Description=RTKLIB Service After=network.target Wants=network-online.target After=network-online.target
[Service]
ExecStart=/path/to/rtkrcv -s -o /path/to/rtkrcv.conf
Restart=always
RestartSec=120 # 2 minutes (in seconds)
TimeoutStartSec=300 # Set a 5-minute timeout (adjust as needed)
User=root
[Install]
WantedBy=default.target
```
- Enable and Start The Service
bash sudo systemctl daemon-reload sudo systemctl enable rtklib.service sudo systemctl start rtklib.service
- Verify the Service
bash sudo systemctl status rtklib.service
Option 3: Docker Container
1. Install Docker
Consult the following guides for more information on how to install docker
- https://www.digitalocean.com/community/tutorial-collections/how-to-install-and-use-docker
- https://docs.docker.com/engine/install/
- https://docs.docker.com/engine/install/ubuntu/
2. Run the Docker Container
Run our Docker container , ensuring that you provide the necessary environment variables and parameters:
You don’t have to specify both Onocoy and RTKDirect credentials. The backend script is smart and looks to see if they have been set. You can use one or both and this should function perfectly.
If the environment variable
ONCOCOY_MOUNTPOINT
is specified, the docker container will use NTRIPSERVER, otherwise it’ll use RTKLIB for the connection to Onocoy. The container will use RTKLIB for the splitting of the feed and connection to RTKDIRECT still however.
Note: The onocoy dashboard/explorer won’t provide you with the mountpoint information until they verify you can send them data. Omit the mountpoint details from this section until after you initially get past that window. Then run the command again.

- Select
NTRIP Server
as one of your output devices and configure it using the credentials and settings you got from the onocoy console .
- Hit the
Start Button
Windows Option 2: SNIP
On windows, our options are limited. One of the NTRIP communities favorite options for Windows is Snip . While there is a trial available, you’ll need to purchase the software long term if you plan on ever using it for more than an hour at any given time.
- Download and install Snip from the download page .
You’ll have to give them an email and get the download link in your email. Use a service like 10minutemail to avoid getting spam in your email.
- Once installed, go to the relay streams tab tab and delete all options from that page.
- Under the Serial Streams Tab add your COM device and create a serial stream device.
Learn more about how to add a serial stream source device on Snip
- On the Pushed-Out Data Tab manually add the Ntrip server information from the onocoy console .
Troubleshooting and Verifying GPS Connectivity on Linux
- Stop the ntripserver service
sudo systemctl stop ntripserver.service
- Use a GPS tool to verify connectivity
- First, make sure you have gpsd installed:
sudo apt-get install gpsd
- Then start gpsd to connect to your GPS device:
sudo gpsd /dev/ttyACM0 -F /var/run/gpsd.sock gpsmon
- First, make sure you have gpsd installed:
- When finished either reboot your device or run
sudo systemctl start ntripserver.service
Notible Mentions for Alternative Ntrip Server Software.
While reviewing this topic and discussing with the Onocoy team on their discord, I came across the following. These may work better for you but we didn’t cover them here. We may review them another time.
- Ntrip Server
- Seems to be a newer version of the software we used above. However it’s more difficult to access. It is created and maintained by the German Federal Agency for Cartography and Geodesy (BKG)
- RTKLIB STR2STR
- A more widely used Ntrip server. However it can be significantly more technically involved.
- rtklibexplorer/RTKLIB
- A version of RTKLIB optimized for single and dual frequency low cost GPS receivers, especially u-blox receivers. It is based on RTKLIB 2.4.3 and is kept reasonably closely synced to that branch.
- A fork of the original RTKLIB that is known to be more frequently updated and more optimized than the original RTKLIB.
- The variant of RTKLIB we use in our docker container.
- esp32-xbee
- Exclusive to the ESP32, this software enables you to build even cheaper base stations. Or more expensive…
Additional Configuration For Unicorecomm UM980 and UM982 Devices
To enable all the bands and base station mode on the Unicorecomm devices you’ll need to serial into them using baud rate of 115200
and run the following commands. This can be done within terminal, putty, or the
Unicorecomm UPrecise
software.
The provided configuration adjustments are made to ensure the proper functionality of the reference station receiver, specifically tailored for the Onocoy system . Click here understand What RTCM Messages Onocoy supports .
Unicorecomm UM980 and UM982 Configuration Script
Note: Not all of these commands will work on all UM980 or UM982 varients. Some commands are firmware specific some are redundant. Not all commands are required. These are just what we determined to be “most optimal” for most situations for both Onocoy and for any other service you may use your UM98x with.

KERNEL=="ttyUSB[0-9]", \
ATTRS{idVendor}=="0403",ATTRS{idProduct}=="6015", \
SYMLINK+="ttyUM980"
Maintaining UPrecise Access with Linux using Socat
To ensure uninterrupted UPrecise access when using Linux, you can utilize the socat
application to connect to the UM980’s serial interface from a Windows machine.
Here’s the command to achieve this:
Replace {{portnumber}}
with a port number of your choosing
sudo socat tcp-listen:{{portnumber}},reuseaddr /dev/ttyUSB0,b115200,raw,echo=0
Next, follow these steps to set up UPrecise on a Windows PC within the same network:
- Launch UPrecise.
- Navigate to the “Connections” menu.
- Select “TCP/IP” as the connection type.
- Enter the IP address of your Linux host and the port number specified in the previous command.
- You will now have access to the Data Stream and can continue sending commands as usual.

Onocoy Devices & Streams
Q5: Can streams be retrieved directly if my station only supports NTRIP caster and is exposed on the internet?
- A5: No, due to complexities, it is not a reliable method. Contact your station manufacturer to add NTRIP server functionality.
Q6: What NTRIP Messages need to be enabled on my GNSS reference receivers for the best rewards?
- A6: Enable RTCM 3.0 MSM7 Messages for optimal rewards, including messages for various constellations. Lower tier messages are supported, while certain message types are ignored.
Q7: What latency is tolerable from the GNSS receiver to the onocoy system?
- A7: The end-to-end latency should be below 1 second; larger latencies result in reduced rewards and potential disconnection.
Q8: Do I have to set the receiver in a special Reference station mode to determine its accurate location?
- A8: No, the onocoy system’s validation procedures determine the precise location of your station.
Q9: How does onocoy prevent fraudulent correction streams?
- A9: onocoy employs sophisticated methods, including regular data consistency checks, real-time supervision, and checks over long-term periods to detect fraudulent streams.
Q10: Can I provide data from a 3rd party service, such as public networks like IGS or other networks?
- A10: Yes, with acceptance of terms and conditions, provided you have the rights. Multiple submissions from free networks may result in banning.
Q11: My station frequently disconnects. What can I do?
- A11: Disconnections are observed due to updates but should not affect operations. No action is needed on the user’s network side.
Onocoy Rewards
Q12: My wallet is not connecting. What can I do?
- A12: Ensure you are using Chrome or Brave Browser on a Desktop device. Follow instructions on the page, and if issues persist, contact support through the onocoy discord .
Q13: How is the location scale calculated?
- A13: Factors include the number and distance of nearby stations, with the quality of neighboring stations influencing rewards.
Q14: How much will I earn streaming RTK correction data to onocoy?
- A14: Earnings depend on factors like signals, satellites, and location. Specific numbers are yet to be decided, but users can earn tokens even before they are officially listed.
Q15: Why does onocoy use blockchain technology?
- A15: onocoy uses blockchain to stabilize token prices, with mechanisms like required tokens for data access, constant burn, locked tokens for governance, a capped maximum supply, and a staking function.
Q16: How do I claim my rewards?
- A16: Click the “Claim Rewards” button in your NTRIP server list in the Onocoy Dashboard. Rewards can be claimed anytime, and changes in the reward factor trigger automatic claiming. Review your current balance in the upper right corner of the validator.
