I would ask directly on the Quectel forum so that you can get the latest versions. If not, send me a PN
Yesterday and today I was able to compare the Quectel and the u-blox f9p mounted on the same copter (not at the same time, but at the same position). One of the things I wanted to check was how exactly the copter land back at the home point after triggering an RTL.
I was completely satisfied with the u-blox. Here’s the cut together: https://vimeo.com/983959416
I didn’t even send the Quectel on its journey with the previous waypoints and saved myself the extensive time for film cutting after it touched down more than a metre away from the target point during the first “RTL” test.
I noticed the same thing as @dennis_bowman1 at Firmware Request: LC29HEA Adjustable Update Rate for Ardupilot Utilization - #18 by dennis_bowman - Upgrade/Debug - Quectel Forums
ublox f9p:
LC29HEA:
Both GPS report RTK FIX !
The LC29HEA does not send hAcc messages, no variometer data, which I personally do not find optimal. I hope that I will soon have time (and weather conditions) to repeat the flights.
