GRS-1

Topcon Positioning System's (TPS) new GRS-1 is the world's first fully integrated dual constellation network enabled RTK rover system. It is an all-in-one handheld GNSS receiver and field controller with highspeed processor, increased memory, built-in camera and compass. Also integrated into the new system are SD memory card slot,
optional internal GSM or CDMA modem, and connectivity via Wireless LAN and Bluetooth® wireless technology.

The GRS-1 (Geodetic Rover System) was designed with two primary system design goals: smaller size and weight, and lower cost. The new receiver has DGPS capability
with internal L1 antenna for use in the GIS and navigation space, add the PGA-1 external antenna and connect to your local GNSS network via the internal modem, and instantly move to dual frequency, dual constellation GNSS centimeter RTK accuracy! The GRS-1 can also be used as a static post processed receiver system.

Utilizing the popular TopSURV surveying software the GRS-1 operates with the Windows Mobile® operating system. Version 7.2.2 of TopSURV adds new features and functions that are unique to the GRS-1 capabilities.
