In a survey system involving either differential global positioning (DGPS)
or robotic total station (RTS) systems, the mobile station includes the
radio system in the surveyor pole and either connects the laser reflector
system or the GPS to the top of the pole or provides a connector for
releasably connecting the laser reflector system or GPS. Electric
connections between the GPS or laser reflector system, and the radio
system are made either by using the physical connector between the pole
and the GPS or laser reflector system, or by providing separate
electrical conductors and electrical connectors from the pole to the GPS
or laser reflector. In the case of a RTS system the base station includes
a GPS for locating the position of the base station. For added
convenience, the pole may be formed in sections and the power supply may
include an inductive coupling battery charger. Data communications may
also take place using wireless technology such as Bluetooth.
