HOLUX GR-86 is a high performance, low power consumption, small size, very easy integrated GPS engine board 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 SiRFstar III chipsetm solution. The GPS engine board 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 engine board 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 TTL voltage level.
