The main advantage of the ROS drivers contained in this repository is the support of a two link communication for GPS corrections: Xbee (radio link) and WiFi (UDP messages). Corrections are sent from the Base Station to the Rover/MAV. This two-ways link strengthens the robustness of the RTK fix, as it increases the chances for correction message, either sent via Xbee or Wifi, to be received by the Rover/MAV.
There are a few parameters you need to set to be able to send/receive corrections over Wifi:
Corrections over WiFi were tested even as a stand-alone solution, without the usage of a radio link. They proved to be a reliable solution and the Rover/MAV receiver could get an RTK fix in less than 10 minuts.
