GPS Receivers
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)
