Do you then use the internet to find the local pressure, or only use it to calculate changes in altitude?

- traverseda 2y agoIt's one factor in estimating altitude you feed into an extended kalman filter. If the GPS altitude is holding steady but there's a sudden jump in pressure that's probably a storm front not indicative of motion. You also probably want an accelerometer.
