Introduction HOLUX GR-86 Ver D is a high performance, low power consumption, small size, very easy integrated GPS module designed for a broad spectrum of OEM system applications. This product is based on the proven technology found in other HOLUX 20 channel GPS receivers and SiRF GSC3 chipset solution. The GPS module will track up to 20 satellites at a time while providing fast time-to-first-fix and one-second navigation updates. Its far reaching capability meets the sensitivity requirements of car navigation as well as other location-based applications. Therefore, HOLUX GR-86 module is very fit to the customers who devote themselves to AVL system integration and location-based service. The GR-86 design utilizes the latest surface mount technology (BGA) and high level circuit integration to achieve superior performance while minimizing space and power requirements. This hardware capability combined with software intelligence makes the board easy to be integrated and used in all kinds of navigation applications or products. The application system may communicate with the engine board set via CMOS 3V voltage level. 2. Main Feature Build on high performance SiRF GSC3f chipset. Average Cold Start time and under 42 seconds. Low power consumption 20 channels "All-in-View" tracking. Integrated ARM7TDMI CPU with software engineering services and available for embedded customer defined applications. On chip 1Mb SRAM. On-board LNA and saw filter. Dual CMOS 3V serial ports with one for GPS receiver command message interface. Compact board size 24x24x3 mm for easy integration into hand-held device.

Software Interface The GR-86 interface protocol is based on the National Marine Electronics Association's NMEA 0183 ASCinterface specification, which is defined in NMEA 0183, Version 2.2 and the Radio Technical Commission for Maritime Services (RTCM Recommended Standards For Differential Navstar GPS Service, Version 2.1, RTCM Special Committee No.104). As soon as the initial self-test is complete, the GR-86 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-86 utilizes initial data, such as last stored position, date, time and satellite orbital data, to achieve maximum acquisition performance. If significant inaccuracy exists in the initial data, or the orbital data is obsolete, it may take more time to achieve a navigation solution. The GR-86 Auto-locate feature is capable of automatically determining a navigation solution without intervention from the host system. However, acquisition performance can be improved as the host system initializes the GR-86 in the following situation: 4.1 NMEA Transmitted Messages The default communication parameters for NMEA output are 4800 baud, 8 data bits, stop bit, and no parity.

Position accuracy of less than 5 meters can be achieved with the GPS-82 by using Differential GPS (DGPS) real-time pseudo-range correction data in RTCM SC-104 format, with message types 1,2, or 9.
