Do you change anything in the Reach settings when this message appears? If Mission Planner shows the Bad GPS Signal Health message, it’s essential to check that the GNSS update rate on Reach is 5 Hz or higher.
What is the Solution status on Reach when you get the Bad GPS Signal Health message? It may happen when Reach isn’t provided with a non-obstructed sky view which causes the signal to be not of good quality. For example, if you fly near tall buildings.
I was not at all help to get RTK work with my Reach M2 after very long chat.
But atleast here one user got solution from himself not with technical support from emlid .
As a manufacturer emlid itself couldn’t provide proper solution to work around and get better result.
I just followed emlid and ardupilot forum and also there manuals and documents to get it work but still no luck…emlid said set NMEA protocol at some baudrate( I forgot the baudrate which I was set),but now from user point they concluded that RTK work with ERB protocol at 57600baudrate.
Please provide a valid document or support to your user to work .please conclude here atleast at what setting Reach M2 RTK works. I have searched emlid forum regarding this but 90% nobudy succeeded.
but I need centimeters accuracy flying, as you can see at picture above, I developed precision spraying. I can’t achieve that with here3 GPS (already try that)
then I use emlid M2 as my primary GPS. connected to RS2 for RTK.
for now, more than hundreds flight I use this configuration
