GPS Antenna/Receivers

GR301 GR301

A low cost water resistant (IPx7) GPS receiver/antenna (smart antenna or GPS Mouse) for automatic vehicle location (AVL) and vehicle tracking.

The GR301 Smart GPS Receiver is designed based on SiRF Star III Architecture. It communicates with the mobile data terminals via RS232 and a USB adaptor is available for connection to other devices. With low power consumption, the GR-213 tracks up to 20 satellites at a time, re-acquires satellite signals in 100 ms and updates position data every second.

Features

1. SiRF Star III high performance and low power consumption chipset.
2. All-in-view 20-channel parallel processing for fast aquisition & reaquisition
3. Built-in active antenna.
4. High sensitivity to satellite signal.
5. Fast TTFF (Time-To-First-Fix), at low signal level
6. Built-in rechargeable Lithium-ion battery for TTFF
7. Support NMEA 0183 v3.0 data protocol
8. Superior performance in urban, canyon and foliage environments.
9. Cold start under 42 seconds, average.
10. Hot start reacquisition less than 1 second average.
11. Low power consumption and mini size.
12. Supported NMEA 0183 command:GGA, GSA, GSV, RMC, VTG
13. SBAS Support: WAAS, EGNOS (optional)
14. Non slip magnetic mounting
15. Water resistant design (IPx7)
