GeoSIG GMS-GPS
Key Features
- Concurrent reception of up to 3 GNSS (GPS, Galileo, GLONASS, BeiDou)
- Supports all satellite augmentation systems and Assisted GNSS (A-GNSS)
- 30 nanosecond time accuracy (RMS)
- < 2.5 m position accuracy GPS
- < 1 second re-acquisition
5 seconds warm acquisition
45 seconds cold acquisition - RS232 or optionally RS485 communication
- Built-in antenna or external antenna
- Rugged, water resistant housing
The GMS-GPS is a state of the art GPS receiver module which employs U-BLOX NEO-M8N that is a complete GPS receiver and embedded antenna designed for a broad spectrum of system application.
The NEO-M8 module is concurrent GNSS receiver, which can receive and track multiple GNSS systems: GPS, Galileo, GLONASS and BeiDou. Its far-reaching capability meets the sensitivity requirements of seismic applications and low power consumption.
The NEO-M8N design utilises the latest technology and high level circuit integration to achieve superior performance while minimising space and power requirements.
The GMS-GPS is housed in a water-resistant case and is designed to withstand rugged operating conditions. The host system may communicate with the GMS-GPS via a dedicated, compatible, bi-directional communication channel. Internal memory backup allows the GMS-GPS to retain critical data such as satellite orbital parameters, last position, date, and time.
