SparkPNT TX2 (GPS-29524)

  1. Can one TX2 act as a Base (sending out RTCM corrections over radio) while another TX2 acts as a Rover, receiving those corrections over radio to achieve RTK FIX?
    1. I.e. Without using PointPerfect or other external corrections service
  2. What’s the range of the ESP-NOW radio and is that the radio over which the two TX2 units described above would send/receive RTCM messages?

Context: I would like to use two of these (base and rover) with Bluetooth disabled and no internet connection. I will be connecting the rover to my laptop and pull the data over the USB-C cable.

Thank you for your time!

  1. Yes - you’d take a look at ‘Survey-in’ for a temporary/relative positioning workflow or ‘Fixed’ for situations where the base will be in the same spot…both of these sacrifice a bit of accuracy but are workable if ~30cm suits your needs (otherwise you’d need a 24 hr survey and submit it to register/validate a base)

  2. Anywhere from 40 to a few hundred meters depending on what’s in the way :wink: Our tests worked to about 250m; see more info here

For the usb see here (it’s just another section of the TX2 guide, like the 2 links above…feel free to poke through it!)
