All-in-one handheld GNSS receiver and field controller

Topcon continues to enhance GNSS receivers by adding Vanguard TechnologyTM to the already successful GRS-1. The GRS-1 now featuring Vanguard TechnologyTM has 226 GNSS channels that use Universal Tracking Technology for unmatched GNSS signal flexibility and expandability. It is an all-in-one handheld GNSS receiver and field controller with high speed processor, bright sunlight readable screen, and optional internal camera. It is packed with communications as well. Bluetooth®, WiFi, and choice of CDMA or GSM modem.

An improved World’s First
The GRS-1 (Geodetic Rover System) was designed as a world’s first fully integrated dual constellation network ready RTK rover. Now with Vanguard TechnologyTM, it can also receive Galileo signals. It still has DGPS capability with the internal single frequency antenna for use in GIS and navigation applications, add the external antenna and connect to your local GNSS network, or MAGNET Relay base for centimeter accuracy RTK performance.

Versatile for all applications
Use the GRS-1 in various configurations from handheld to network enabled RTK measurement, and grade management. The system can be configured to perform at various levels of accuracy that fit any budget. Choose from centimeter level, sub-decimeter, sub-meter, or DGPS. All of these accuracy configurations can be upgraded by a simple options file purchase. The computer processor and screen are powerful and ready to run all of Topcon’s field applications, MAGNET Field, MAGNET Field Site, Pocket-3D, eGIS, and other partner software.
