Improving Android GPS Accuracy to Complete Site Survey

Survey and Drone Mapping - what do I need?

Just get (2) RS+ and a M+ (get LoRa antenna option for the M+ too) if budget low. i wouldnt skimp on only 1 RS+, you’ll appreciate having the extr as capability when you really wished you had it. Or if budget justifies (2) RS2 rather the (2) RS+, GET THEM!

Or you can get only (1) of either RS+ (single L1 freq.)or RS2 (new just released multifreq.) and use as Rover and use NTRIP CORS for your Base until you can get another RS+ or RS2.

I’d rather have (2) so i wasn’t dependent on CORS and internet, cellular if out of range of them. Otherwise you can use LoRa (LongRange) between your Base and Rover.

Fyi, getting a M+ is if you plan on using a drone since the price is cheap. If not, you don’t need it. Keep in mind that M+ doesnt have builtin LoRa like the RS+ and RS2. You have to buy that additional.
