GPS Receivers
GR213
A low cost
water resistant (IPx7) GPS receiver/antenna
(smart antenna or GPS Mouse) for automatic
vehicle location (AVL) and vehicle tracking.
The GR-213
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-Fast-Fix), at low
signal level
6. Built-in hardware Tracking Loop Processor WAAS/EGNOS Demodulator support
7. Built-in rechargeable Lithium-ion battery for TTFF
8. Support NMEA 0183 v2.2 data protocol
9. Superior performance in urban, canyon
and foliage environments.
5. Cold start under 45 seconds, average.
6. Hot start reacquisition less than 3 secs
average.
7. Superior urban canyon performance.
8. Foliage Lock for weak signal tracking.
9. High speed signal acquisition using 1920
time/frequency search channels.
10. Low power consumption and mini size.
11. Supported NMEA 0183 command:GGA, GSA,
GSV, RMC, GLL, VTG
12. Non slip magnetic mounting
13. LED indicator for GPS fix or not fix
14. Built-in rechargeable battery for memory
and RTC backup
15. Water resistant design
(IPx7)
