GeoLink module is aiding peripheral for Spirit System units. It is utilizing Global Navigation Satellite System (GNSS) to acquire absolute position on Earth. To further improve precision it is embedded with Pressure, Temperature, Humidity sensors and also Gyroscope, Accelerometer and Compass sensors. All the signals are processed in a dedicated 32bit processor. This makes it extraordinary solution for R/C models.
A satellite navigation system with global coverage consists from:
- GPS
- GLONASS
- BeiDou
- Galileo
GNSS technology itself is able to provide precision of up to 2 meters. But thanks to all the algorithms and sensors it was possible to improve the precision by one order. The module can use all these navigation systems at the same time.
In order to operate correctly, it is crucial to provide optimal operational conditions that are mainly secured by correct module mounting on R/C models. It is always beneficial to ensure the best conditions as it is directly related to positioning precision, GNSS signal stability and time to first fix (TTFF).
Time To First Fix
Whenever powering the module it starts by searching for all nearby satellites.
