Topcon engineers have incorporated our industry leading dual-constellation satellite tracking into a small hand-held GPS receiver, the new GMS-2.

This innovative new system also provides an integrated electronic compass and digital camera powered by Topcon’s revolutionary imaging technology. This powerful combination of dual-constellation satellite performance and digital imaging technology has set a new standard for GIS field mapping.

GMS-2 features:

  • Dual-Constellation Satellite Tracking

  • Integrated Digital Camera & Electronic Compass

  • Dual-use performance as GIS receiver or Field Controller

  • Internal Bluetooth® Wireless Technology Connectivity

  • Ultra Sharp Color TFT Touch Screen

Powered by Topcon’s TPSCORE® GPS chip technology, the GMS-2 provides 50 channel tracking capability, for both GPS+ Glonass satellite systems. The TPSCORE® chip technology also provides dual-purpose signal tracking for either meter-level GIS mapping applications, or single frequency carrier tracking for high accuracy static positioning. With an optional external L1 antenna, the GMS-2 can perform post processed surveying applications for accuracies better than 1 cm.

In addition to post-processed DGPS capabilities, the GMS-2 can utilize external correction services for real-time DGPS mapping and navigation applications. The GMS-2 provides access to the WAAS and EGNOS correction services as a standard feature. Using its internal Bluetooth connection, the GMS-2 can be configured to connect to a regional GPS reference station network using a Bluetooth Dial-Up networking enabled cell phone. When utilizing the optional Topcon BR-1 Beacon Receiver, the GMS-2 can correct its raw GPS location using a Coast Guard Beacon real-time correction service for increased real-time location mapping and navigation accuracies.

With the revolutionary integration of a digital camera into a hand-held GPS unit, users can now automatically attach and store photographs to a location in the field. This increases the functionality of the system, while decreasing the amount of equipment a user has to carry and configure.

A significant advantage of the GMS-2 is its ability to perform multiple roles. With its Windows CE® operating system, a GMS-2 can also be configured to be a field controller running the full suite of Topcon’s TopSURV software to work with total stations and RTK GPS systems. With the addition of the GPS+ & GIS modules for TopSURV, the GMS-2 can be used as either a stand alone GIS receiver, or as part of an integrated system, providing flexibility not found in competing systems.
