1. Introduction
1.1 Overview
The Rikaline GPS-300 Black Box is a total solution GPS receiver, designed based on SiRF Star II
Architecture. It is pre-installed and fixed in your car or boat without extra wiring. This positioning application
meets strict needs such as car navigation, mapping, surveying, security, agriculture and so on. 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 GPS-300 tracks up to 12 satellites at a time,
re-acquires satellite signals in 100 ms and updates position data every second.
1.2 Features
The GPS-300 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. 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 “Blinking” when power
connected and “Stays ON” when GPS-300 position identified. No more extra device needed.
11. Built-in WAAS demodulator.
12. Full set accessory for installing in the car and using with your devices.
