AQ-300-U GPS Receiver User’s Manual Guide
The AQ-300 Smart Antenna is a total solution GPS receiver, designed based on SiRF Star II Architecture. The AQ Max GPS technology is a low power (70mA), cost effective and easy integration GPS system. 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. AQ-300 tracks up to 12 satellites at a time, reacquires satellite signals in 100 ms and updates position data every second. A sleeping mode will save power consumption dramatically to allow critical low power applications.
The AQ-300 provides a host of features that make it easy for integration and use.
1. SiRF Star II chipset with embedded R3000 level, MIPS I class, 32-bit RISC processor 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. It 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 AQ-300 position identified. No more extra device is needed.
11. Built-in WAAS demodulator.
12. Built-in magnets for using on top of the car.
13. Waterproof (1 meter) design for all weather.
