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 sec-
ond 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 rov-
ers, 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.
The rover system for a kinematic survey is set up in a slightly different manner due to
the fact that kinematic data collection is dynamic in nature, i.e. the operator must be
