Topcon, the company that brought you the first integrated GPS receiver now brings
you the first fully integrated handheld GNSS receiver and field controller!
Small & Lightweight Design—ideal network rover
Scalable & Expandable—handheld or on-the-pole
Multi-function—survey/map/navigate/communicate
Topcon’s new GRS-1 (Geodetic Rover System) 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 featuring high-speed processor, increased memory, built-in camera
and digital compass. Also integrated are an SD memory card slot, optional internal GSM or CDMA
modem, and wireless connectivity via Wireless LAN and Bluetooth® wireless technology.
The GRS-1 achieves three primary and evolutionary goals for a GNSS receiver: small size, minimal
weight, and affordability. It provides DGPS capability via an internal L1 antenna, perfect for the GIS
and navigation space. Instantly move to centimeter RTK accurate dual frequency / dual constellation
GNSS by simply adding a carbon-fiber pole with Topcon’s PGA-1 external antenna then connect to
your local GNSS network via the internal modem. As an added benefit, the GRS-1 can also be used
as a static post processed receiver system.
