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.

Why DIY a Onocoy Reference Station?

Firstly, it provides a cost-effective solution, enabling you to save on setup expenses while achieving high precision in location-based applications. Secondly, the customization options allow you to tailor the hardware and software to your specific needs, enhancing flexibility and adaptability. Moreover, DIY setup empowers you with a deeper understanding of the technology, enabling you to troubleshoot and innovate. Lastly, contributing to the Onocoy network not only improves your own accuracy but also lets you play a vital role in advancing global navigation systems while earning rewards for your data contributions.

Hardware Requirements:

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 raspian on your Raspberry PI

• Orange Pi 5 4GB
• Raspberry Pi 4B Model B DIY Kit
• GeeekPi Raspberry Pi 4 4GB Starter Kit
• GeeekPi Raspberry Pi 4 8GB Starter Kit

Any USFF/Tiny/Mini/Micro PC:

• Lenovo ThinkCentre M900 Tiny
• Dell OptiPlex 7040 Micro USFF

Any Mini PC with Intel N5100 or similar

For super low power Raspberry Pi equivalent but on x64 platform.

• Beelink U59 Mini PC
• TRIGKEY Mini Computer

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.

Proper Onocoy Base Station Antenna Placement

Onocoy has published antenna placement requirements , but to summarize you should understand the following:

1. 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.

2. 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.

3. 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.

1. 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.

2. Install some base dependencies.

   sudo apt install -y gpsd gpsd-dbg gpsd-clients gpsbabel minicom socat git make build-essential
   

3. Follow one of the Options Below. Either NTRIP Server or RTKLIB

4. Wait and Verify Your Station on the Onocoy Dashboard

   1. 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.

5. Profit?

   1. You can view the following Onocoy documentation to learn more.

Option 1: NTRIP Server

1. On your linux device download the ntripserver software.

   git clone https://github.com/simeononsecurity/ntripserver.git
   cd ./ntripserver
   make
   

2. Identify the USB Source

   lsusb
   

   Ex. Bus 00x Device 00x: ID xxxx:xxxx Prolific Technology, Inc. PL2303 Serial Port / Mobile Action MA-8910P or Bus 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
   

3. Now we get to configure the software

   1. Test the configuration.

          ~/ntripserver/ntripserver -M 1 -i /dev/ttyUSB0 -b 19200 -O 1 -a servers.onocoy.com -p 2101 -m {{mountpointhere}} -n {{usernamehere}} -c {{passwordhere}}
      

   2. Now that you confirmed it works. We need to create a service to have it restart on boot.

      1. 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 19200 -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
      

      2. Enable and Start the Service:

      sudo systemctl enable ntripserver.service
      sudo systemctl start ntripserver.service
      

      3. Check the Service Status:

      sudo systemctl status ntripserver.service
      

      ex.

      ntripserver[815]: serial input: device = /dev/ttyUSB0, speed = 19200
      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

1. On your linux device install the rtklib software.

   sudo apt-get update
   sudo apt-get -y install rtklib
   

2. Identify the USB Source

   lsusb
   

   Ex. Bus 00x Device 00x: ID xxxx:xxxx Prolific Technology, Inc. PL2303 Serial Port / Mobile Action MA-8910P or Bus 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
   

3. Create a Rtkrcv.conf RTKLIB Configuration File

   1. Create the paths and conf file

   sudo mkdir ~/rtklib/
   sudo nano ~/rtklib/rtkrcv.conf
   

   2. Conf File Contents

   [serial]
   port = /dev/ttyUSB0
   bitrate = 19200
   [ntrip]
   caster = servers.onocoy.com
   port = 2101
   mountpoint = {{mountpointhere}} 
   user = {{usernamehere}}
   passwd = {{passwordhere}}
   [output]  
   format = rtcm3
   path = /path/to/output/file.rtcm
   

   3. Test the RTKLIB config

     rtkrcv -s -o ~/rtklib/rtkrcv.conf
   

4. Create the RTKLIB Service

5. Create the Service Unit File bash sudo nano /etc/systemd/system/rtklib.service

6. 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
```

3. Enable and Start The Service bash sudo systemctl daemon-reload sudo systemctl enable rtklib.service sudo systemctl start rtklib.service
4. Verify the Service bash sudo systemctl status rtklib.service

Option 3: Docker Container

Windows Option 1: STRSVR

On windows, one of our best options and arguably our best free option is STRSVR , which is based on RTKLIB.

1. Download and save STRSVR.exe from the github releases page . Be sure to save it to a good location that you can easily find again later.

2. Execute STRSVR.exe, select Serial as your input device, and configure the correct COM Port for your serial reciever.

Note: Your com port will be different on your device. Consult your manufactures documentation and the Windows Device Manager on to identify the correct com port

3. Select NTRIP Server as one of your output devices and configure it using the credentials and settings you got from the onocoy console .

4. 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.

1. 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.

2. Once installed, go to the relay streams tab tab and delete all options from that page.

3. 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

4. On the Pushed-Out Data Tab manually add the Ntrip server information from the onocoy console .

Learn more on how to add pushed-out data streams on snip

Troubleshooting and Verifying GPS Connectivity on Linux

1. Stop the ntripserver service

  sudo systemctl stop ntripserver.service

2. Use a GPS tool to verify connectivity
   1. First, make sure you have gpsd installed:

      sudo apt-get install gpsd
      

   2. Then start gpsd to connect to your GPS device:

      sudo gpsd /dev/ttyACM0 -F /var/run/gpsd.sock
      gpsmon
      

3. 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
  • A more widely used Ntrip server. However it can be significantly more technically involved.
• 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 .

1. mode base time 60 2 2.5: This line configures the reference station’s operation mode, which is set to “base”. In this configuration the base station will figure out it’s actual location after receiving traffic for 60 seconds.

2. CONFIG SIGNALGROUP 2: This command appears to configure the signal group for the UM980/UM982 devices. This enables all bands and frequencies on the device.

3. rtcm1005 30 and rtcm1006 30: These commands set the rate at which RTCM messages 1005 and 1006 are sent out from the reference station, respectively. The values “30” suggest a 30-second interval, which is optimized for Onocoy system’s requirements .

4. rtcm1033 1, rtcm1074 1, rtcm1077 1, rtcm1084 1, rtcm1087 1, rtcm1094 1, rtcm1097 1, and rtcm1117 1, rtcm1124 1 and rtcm1127 1: These commands enable RTCM messages per Onocoy system’s requirements , ensuring that the reference station transmits these specific messages. The value “1” enables these messages to happen every second..

5. saveconfig: This command saves the configured settings, ensuring that they persist and are applied whenever the reference station is operational.
