We wanted to start narrowing down the reason's for why we keep losing the Shrike! We are starting with understanding which materials placed over the GPS module affect reception. We placed clear plastic, tape, a phone book, dow foam, aluminum foil, static brushless motor, powered and turning brushless motor, powered tx 2.4 GHz, and powered vtx 5.8 GHz directly over the module before booting the APM. We noted how many satellites connected after 2 minutes.
We found that most of the materials had negligible effects on satcount under the Flight Data>Status in the APM planner. Aluminum Foil, the brushless motor, and the 2.4 GHz signal created the largest interference.
Let us know how we could improve this experiment! We are not sure how well satcount correlates to the actual ability to navigate. Once we have telemetry we will be able to explore this further.
See you soon!
