3 Rover Station Setup and Operation
This chapter provides the information to help the user identify good setup locations,
describes the conventional process to set up the rover station and the configuring
procedure that required for receiving correction data.
3.1
Rover Station Setup Guidelines
For good rover operation, please follow the following setup guidelines:
Place the GNSS antenna in a location that has a clear view of the sky in all directions.
Do not place the antenna near vertical obstructions such as buildings, deep cuttings,
site vehicles, towers, or canopy. GNSS rovers and the base station receive the same
satellite signals from the same satellites. The system needs at least five common
satellites to provide RTK positioning.
WARNING – Do not touch overhead power lines with the CHC X900U+ GNSS
receiver or the range pole when moving the equipment into position. Touching
overhead power lines may cause electrocution, leading to serious injury.
•
GNSS satellites are constantly moving. The fact that user cannot measure at a
specific location at the moment does not mean that user will not be able to
measure there later when satellite coverage at the location improves.
•
To get a fixed position solution with centimetre precision, initialize the RTK rover
receiver. For initialization to take place, the receiver must track at least five
satellites that the base station is also tracking. In a dual-satellite constellation
operation, for example, GPS and GLONASS, the receiver must track at least six
satellites.
•
To continue to survey at centimetre precisions, the rover must continuously track at
least four satellites that the base station is also tracking.
•
Loss of the satellite signals will result in a loss of centimetre position precision.
