Hi Truett,
Thanks for sharing the details!
We’ve seen that Pixhawk’s power output may not always be enough for Reach, which is why we suggest external power in our guide. Here are the setups that worked for others:
-
via the S1/S2 port on M2 and GPS2 on Pixhawk. Using two power sources simultaneously may damage the M2, so you’ll need to cut the +5V wire. You can check this thread as a reference.
-
via USB. One of the users found it easier to cut the +5V wire entirely and power the M2 via USB.
Before making any changes, though, let’s rule out other factors. As I see, the corrections are not injected to the telemetry unlike our Ardupilot guide explains. In your setup, M2 should connect to the Internet, receive corrections over NTRIP, and send its accurate position to the Pixhawk. If I got this right, the settings should be:
-
Correction input: Your NTRIP profile (if using Polaris PointOne). I see you’re using a Caster—do you have your own base?
-
Position streaming: Serial
And how is the M2 connected to the Internet?
Can we also test a regular setup first—connecting the M2 to NTRIP and checking if it gets a FIX in Emlid Flow?
