The HOLUX GR-212 Smart GPS Receiver is a total solution GPS receiver, designed
based on SiRF Star II architecture. This positioning application meets strict
needs such as car navigation, mapping, surveying, security, agriculture and
so on. Only clear view of sky and certain power supply are necessary to the
unit. It communicates with other electronic utilities via compatible dual-channel
through RS-232 or TTL and saves critical satellite data by built–in backup
memory. With low power consumption, the GR-212 tracks up to 12 satellites at
a time, re-acquires satellite signals in 100 ms and updates position data every
second. Trickle-Power allows the unit operates a fraction of the time and Push-to-Fix
permits user to have a quick position fix even though the receiver usually stays
off.
Specification:
The GR-212 provides a host of features that make it easy for integration and
use:
1. SiRF Star II chipset with embedded ARM7TDMI CPU available for customized
applications in firmware
2. High performance receiver tracks up to 12 satellites while providing first
fast fix and low power consumption.
3. Differential capability utilizes real-time RTCM corrections producing 1-5
meter position accuracy.
4. Compact design ideal for applications with minimal space.
5. A rechargeable battery sustains internal clock and memory. The battery is
recharged during normal operation.
6. User initialization is not required.
7. Dual communication channels and user selectable baud rates allow maximum
interface capability and flexibility.
8. Optional communication levels, RS-232 and TTL meet ordinary application and
new fashions of connecting PDA with TTL or RS-232 output.
9. FLASH based program memory: New software revisions upgradeable through serial
interface.
10. LED display status: The LED provides users visible positioning status. LED
“ON” when power connected and “BLINKING” when GR-212
got positioned.
11. Built-in WAAS Demodulator.
12. Water proof design for industry standard.
