Arduino software serial and wire library interference how to# Is there something built into the NeoGPS library to find heading so that this is not necessary? was thinking about a combination of GPS output with MPU gyro output (to approximate yaw/heading at any time). NeoGPS does not provide anything like that. The GPS heading is really "direction of travel", not "orientation of platform". It is very common to combine multiple sensors' outputs to reduce the total errors in the estimated "state" (location, altitude, speed, heading, etc.). Kalman isn't as good, and might be more computationally intensive, IIRC. Unfortunately I don't have a compass on my quad. That sort of sensor is best for many situations, because it provides an (almost) absolute orientation. Arduino software serial and wire library interference how to#.
