TOPCON GNSS GMS-2
Topcon engineers have incorporated our industry leading integrated imaging and 50 channel dual constellation satellite tracking into a small hand-held GPS receiver, the GMS-2. This innovative system also incorporates an integrated electronic compass, replaceable/rechargeable battery, and an expandable memory card slot. This powerful combination of technology in such a small device has set a new standard for GIS field mapping.
- Integrated Digital Camera & Electronic Compass
- Internal Bluetooth® Wireless Technology Connectivity
- Removeable / Rechargeable all-day battery
- Expandable Memory Options
- Dual-Constellation Satellite Tracking
- Ultra Sharp Color TFT Touch Screen
Integrated Digital Camera
The internal GMS-2 digital camera allows users to snap digital photographs of GIS features. These photographs are automatically linked to the GIS feature so that extra time is not wasted linking images to features back in the office. The photograph itself can even be geotagged with the GPS coordinate for further detail.
TPSCORE® GPS chip technology
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 two types of signal tracking; code tracking for meter-level GIS mapping. applications, and single frequency carrier tracking for high accuracy positioning. With an optional external antenna, the GMS-2 achieves sub-foot real-time or centimeter level post-processed accuracies.
The GMS-2 can utilize free real-time DGPS correction services for mapping and navigation applications.
The GMS-2 provides access to the WAAS and EGNOS correction services as a standard feature. Using the internal wireless Bluetooth capability, the GMS-2 can be connected to the optional Topcon BR-1 Beacon Receiver to receive Coast Guard Beacon correction data for sub-meter real-time mapping and navigation. The GMS-2 can also be configured to connect to a regional GPS reference station network for real-time corrections using a Bluetooth dial-up networking enabled cell phone.
