[. . . ] It communicates with other electronic utilities via compatible dual-channel through RS-232 or TTL and saves critical satellite data by built­in backup memory. 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. 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. 1. 2 Features The GR-213 provides a host of features that make it easy for integration and use. SiRFstarIII chipset with embedded ARM7TDMI CPU available for customized applications in firmware 2. High performance receiver tracks up to 20 satellites while providing first fast fix and low power consumption. Differential capability utilizes real-time RTCM corrections producing 1-5 meter position accuracy. Dual communication channels and user selectable baud rates allow maximum interface capability and flexibility. Optional communication levels, RS-232 and TTL meet ordinary application and new fashions of connecting PDA with TTL or RS-232 output. FLASH based program memory: New software revisions upgradeable through serial interface. LED display status: The LED provides users visible positioning status. LED "ON" when power connected and "BLINKING" when GR-213 got positioned. Water proof design for industry standard. 1. 3 Technology specifications 1. 3. 1 Physical Dimension Single construction integrated antenna/receiver.

Operational characteristics 2. 1 Initialization As soon as the initial self-test is complete, the GR-213 begins the process of satellite acquisition and tracking automatically. Under normal circumstances, it takes approximately 42 seconds to achieve a position fix, 38 seconds if ephemeris data is known. After a position fix has been calculated, information about valid position, velocity and time is transmitted over the output channel. The GR-213 utilizes initial data, such as last stored position, date, time and satellite orbital data, to achieve maximum acquisition performance.

Position accuracy of less than 5 meters can be achieved with the GR-213 by using Differential GPS (DGPS) real-time pseudo-range correction data in RTCM SC-104 format, with message types 1, 2, or 9. As using DGPS receiver with different communication parameters, GR-213 may decode the data correctly to generate accurate messages and save them in battery-back SRAM for later computing. 6.
