Kinematic Survey

When using the kinematic method of GPS data collection, one of the GPS receiver

systems is designated as the base. This system remains stationary throughout the

survey while the other GPS receiver system, the rover, moves about the project

area positioning objects of interest. If more than two GPS receivers are being used

in the survey, you must decide on how to utilize the additional receivers. If desired,

a second receiver system can be configured as a base and positioned on a point

at the opposite end of the project. A second base system adds redundancy to each

point established with the rover. Optionally, additional receivers can be configured

as rovers, resulting in added productivity during kinematic data collection.

The base system for a kinematic survey is set up in precisely the same manner as

a system set up for a static survey, with one possible exception. During kinematic

data collection, it is recommended that a more frequent recording interval be

utilized. Common recording intervals for kinematic data collection are 1-5 seconds.

Be sure that the recording interval on all receivers are set to the same value.
