Operation instruction
1. Base/Rover Survey by Mission Planner
This part of the tutorial uses Mission Planner ground software and Arducopter-4.3.5 flight firmware for operating instructions.
To use Here 4 Base on a UXV, you need the following hardware£º Computer, telemetry modules, Here4 Base , Base Antenna, Tripod.

Before starting to use, please make sure that the hardware connection is correct:
Ground side: Connect base antenna to base station, then connect the base station module to computer through USB port; Telemetry module is connected to another USB port of the same computer. UXV side: Connect Here 4 Base to CAN interface , telemetry module to the TELEM interface on flight control.

Antenna Placing
Placing the RTK Antenna is very important for getting precise RTK positioning
Normal GPS positioning, only requires you to place the device near a window and it will provide you a GPS location over a period of time. But that's not enough for RTK. For the working environment of RTK, there are special requirements on antenna placement, which are much stricter than GPS.
The best environment for the base and rover antenna is a clear view of the sky that is 30 degrees above the horizon. RTK antenna can be elevated but ensure that there are no obstacles around, such as buildings, trees, cars, and etc
Example of a bad environment: indoors, urban areas, forests, or near the ground.
Example of a good environment: Open spaces, peak of a mountain, roof of a building.
Do not place the antenna near electronic devices, as high power electronic devices in close proximity may affect the radio frequency noise of the GPS signal. Examples are mobile phone base stations, high voltage transformers, etc.
Please place the base station in an outdoor environment with sufficient sky coverage to obtain a good satellite signal.
Place the base station on a stable and elevated platform, such as a tripod.
