CAPELLE AAN DEN IJSEL, The Netherlands - Topcon's new GRS-1 is the world's first fully integrated dual-frequency, duel-constellation, network-enabled RTK rover system. It is an all-in-one handheld GNSS receiver and field controller with internal GSM Modem, high-speed processor, built-in camera, compass and bar code reader.

Features also integrated into the new system are SD memory card slot, and wireless connectivity via Wi-Fi, Bluetooth or optional UHF radio pack.

The GRS-1 (Geodetic Rover System) was designed with two primary system design goals: Smaller size and weight, and lower-than-expected cost. According to Ian Stilgoe, Product Marketing and Support manager, the GRS-1 "packs all the power of a full GPS + GLONASS dual-frequency receiver, cellular modem and Windows PC into a very small, very versatile device for all applications."

Designed primarily as a GNSS network rover receiver, the GRS-1 "provides a small, lightweight rover and a price to fit any budget," he said. "The new receiver has DGPS capability with the internal L1 GPS and Glonass antenna for GIS and navigation, add the PGA-1 external antenna and connect to your local GNSS network via the internal modem, and instantly receive dual frequency, dual constellation GNSS RTK centimeter accuracy. The GRS-1 fits all applications even including post processing."

The GRS-1 uses the Windows Mobile™ operating system to run many applications including TopSURV, Topcon's popular engineering and surveying software and Topcon’s GIS extensions for ESRI’s ArcPAD.

In addition to the network rover configuration, the GRS-1 also has an optional RH-1 radio module to work with existing Topcon GNSS Base station receivers already in the market today. This allows the GRS-1 to work in all areas and sites, even if GSM coverage is not available.


Stilgoe said, "With the GRS-1 network rover, no additional modem or equipment is needed . . . it's all built in. The user can access a GNSS network for decimeter level positioning. The Grs-1 can be wirelessly connected to the Topcon BR-1 Beacon for correction service where no network is present or by attaching an easy-to-connect external antenna, centimeter accuracy is instantly achieved."

The GRS-1 is the world’s most versatile GNSS receiver which meets all your positioning demands.
