I am currently using the Here 3 & Here+ RTK Base (M8P) Combo (https://irlock.com/collections/pixhawk2/products/here-3-here-rtk-base-m8p-combo)
The main issue I am having is I rarely/sporadically get a fixed lock (not for long though). Float is usually accurate enough for us, but the problem is it random drifts 1-6 feet from time to time. Typically this drift/jump happens when its transitioning from Float to Fixed, which happens all the time even with open sky.
From what I have researched F9P makes a big difference. I am thinking of purchasing a Holy bro H-RTK F9P (with the high gain GPS500 antenna) as a start for my base station:
Will I notice a difference just by changing the base station to F9P with a good antenna (while continuing to use the Here 3)?
I am hoping to wait out for the Here Pro GPS (mainly for CAN support) for the rover side which I am assuming will be F9P which will complete my system whenever that it. Or would you suggest not waiting and just buying another Holybro F9P or the Drotek Sirius F9P for the rover at the same time as the base?
The challenge is we fly in urban areas (Film production work) all the time, so the real question is will the F9P be able to hold a fixed lock in these areas or am I still going to suffer from the constant switching between Fixed and Float?
