After taking it to the airfield today, I finally managed to get enough ephemerides data that the GPS now quite quickly locks on, despite the wretched signal quality in my area. I can now properly praise this unit as about the only one doing GPS/IMU/Baro in a single package. Why is this useful? It's an ultra compact way of knowing where you are and what you are looking at, which is great if you want to correlate this with a suitable spatial data field... #gps #electronics #hardware #satellite
