World’s first hand-held GNSS integrated rover system

Dubai, UAE. – 9 Feb'10 – Topcon Middle East releases a  new GNSS solution. The 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 high-speed processor, increased memory, built-in camera, compass and bar code reading function. 

Features also integrated into the new system are an SD memory card slot, optional internal GSM or CDMA modem, and wireless connectivity via Wi-Fi and Bluetooth technology.

The GRS-1 (Geodetic Rover System) was designed with two primary system design goals: Smaller size and weight, and lower-than-expected cost. 

The GRS-1 uses the Windows Mobile™ 6.1 operating system to run TopSURV, Topcon's popular surveying software.  TopSURV 7.2 adds new features and functions that are unique to the GRS-1. The receiver and field controller also has a 3.7 inch, touch screen display and its rugged construction is rated to stand a one meter drop.

In addition to the network rover configuration, the GRS-1 also has an optional RH-1 radio module that can be configured to work with existing Topcon GNSS receiver systems that are already in the market today.  The RH-1 is available in digital UHF, spread spectrum and frequency channel scan UHF varieties. 

All forms of radio correction that current and legacy Topcon GPS+ systems offer are supported within the RH-1 module of the GRS-1 system.  This means that if a customer purchased a previous system from Topcon they can be backwards compatible.
