3. Kinematic survey

The Kinematic technique is typically used for detail surveying, recording trajectories etc., although with
the advent of RTK it s popularity is diminishing. The technique involves a moving Rover whose position
can be calculated relative to the Reference. Firstly, the Rover has to perform what is known as an
initialization. This is essentially the same as measuring a Rapid Static point and enables the postprocessing
software to resolve the ambiguity when back in the office. The Reference and Rover are switched on and
remain absolutely stationary for 5-20 minutes, collecting data. (The actual time depends on the baseline
length from the Reference and the number of satellites observed). After this period, the Rover may then
move freely. The user can record positions at a predefined recording rate, can record distinct positions, or
record a combination of the two. This part of the measurement is commonly called the kinematic chain.
