Abstract
A transmission system for a measurement device on a coordinate positioning apparatus comprises a station mounted on the measuring device and another station mounted on the coordinate positioning apparatus, wherein the station and the another station communicate with each other using a spread spectrum radio link, for example, frequency hopping. The station on the probe sends a regular signal and on receiving the signal the another station on the coordinate positioning apparatus synchronizes its clock and sends an acknowledgement signal. Measurement data is either sent in the regular signal or in a measurement event driven signal.
