To charge the battery and assemble the base station, follow the same procedure as the GCS, detailed here:
To power, the RTK Base Station, first attach the Anker Battery to the back of the Base Station with the installed hook and loop. Then simply plug in the loose USB cable to the Anker Battery.
A blue status LED will confirm power on the front of the Base Station.
Once assembled, place the RTK base station in an open area, away from tall buildings, trees and structures. Directional orientation is not important as it is with the GCS. More information on height considerations of RTK base station setup can be found in the article, RTK for OnTop™.
