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.

Onocoy Reward calculation

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.

Proper Onocoy Base Station Antenna Placement

An Installed Tri-Band GPS Antenna

Installed Antenna -

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.

    onocoy Explorer

    Onocoy Explorer -

  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.
