RTK GPS Research

[MoffKalast]

We need to find a good solution for enabling GPS support on our robots while making use of public RTK base stations.

Something that may be needed is finding a RTKLIB compatible receiver, since there's a ros bridge for it: https://github.com/MapIV/rtklib_ros_bridge

List of RTKLIB compatible devices: https://wiki.openstreetmap.org/wiki/RTKLIB-compatible_GPS_devices

Low end options:

• https://navspark.mybigcommerce.com/ns-raw-carrier-phase-raw-measurement-output-gps-receiver/

• https://www.indiegogo.com/projects/navspark-arduino-compatible-with-gps-gnss-receiver--2#/

• U-blox NEO-M8T

• U-blox ZED-F9P

• https://gnss-sdr.org/

Medium range options:

• https://emlid.com/reach/

• https://emlid.com/reachrs/

• https://emlid.com/reachrs2/

• https://store.swiftnav.com/collections/receivers

• https://store.swiftnav.com/products/precision-gnss-module-pgm-evaluation-kit

• https://www.locosystech.com/en/product/rtk-board-4671-MH.html

Swiftnav has ROS integration and L5 network support, but they're also on the expensive side.

Full on Survey GPS setups seem to cost in the range of $50k a piece, so that's probably out of the question.
