Samenvatting

RTK-GNSS (Real Time Kinematic - Global Navigation Satellite System) is based on a ‘rover’ GNSS
antenna that receives error correction information from a ‘base’ GNSS antenna. While the rover can be
placed on a robot to move around, the base station has the additional ‘knowledge’ of being stationary.
Therefor it is able to recognize any measured motion, caused by atmospheric disturbances to the
GNSS signals coming from satellites, as errors. Assuming the rover antenna is relatively close to the
base station, comparable atmospheric effects can be assumed so the same error corrections can be
applied to the rover antenna. This way, the relative position of the rover antenna with respect to the
base station can be determined with sub-meter or even sub-decimeter accuracy.
