Topcon Positioning System has upgraded its GRS-1 handheld data collector to include sub-decimeter accuracy kits for high accuracy GIS data collection. The RTK GIS kits are designed for jobs with high accuracy applications.

Typical GIS application areas for this accuracy level include asset management, utilities, city and county governments, and water and wastewater management.

For a sub-decimeter solution, the GRS-1 requires either Field Tools for ArcPad (v8 or v10.0) or TopSURV GPS+ software.

In order to utilize the kits to upgrade an existing sub-meter GRS-1 to sub-decimeter RTK, the current GRS-1 must have an internal GSM or CDMA modem. Sub-decimeter and centimeter accuracy is acquired through a connection to a real-time network.
