You are on the list and should have received a Testflight invitation already (resent it a minute ago). You need to register in Testflight and connect your device. Please check the beta forum access in addition and read the initial post. Sent a note on this too.
Thanks Harald – it’s still snowing out now , but our first trip of the year is planned in 3 weeks, so that will be my/our first opportunity to test on a motorbike. With the release of V18 (that allows accelerometer-based, lean-angle corrected calculation of lateral Gs), is there as much value in the peripheral GPS units? My assumption is that the GPS is used primarily for position and velocity, and acceleration is based entirely on the iPhone sensors? We've been using the 'recalculation for acceleration' feature that uses the GPS data to calculate accel, and of course the basic iPhone 1 hz rate was too coarse for that. But thinking that the cheaper XGPS 150 might be just fine (vs the 160) if the iPhone GPS is still considered too slow.
As soon as you recalculate acceleration, it is completely based on GPS. The original acceleration samples are replaced by the recording. So 5 Hz is a benefit, especially when changing directions frequently (AX). For motorbikes, this is no frequent scenario, but you will enjoy the better accuracy delivered by any external GPS.
