Datasheet of GPS mouse, LS2303x series 1.1 1 Introduction LS2303x series products are complete GPS receivers (also known as GPS mouse) based on the proven technology found in LOCOSYS 66 channel GPS SMD type receivers MC-1513 that use MediaTek chip solution. The GPS mouse will acquire up to 66 satellites at a time while providing fast Time-To-First-Fix, one-second navigation update and low power consumption. It can provide you with superior sensitivity and performance even in urban canyon and dense foliage environment. Its far-reaching capability meets the sensitivity requirements of car navigation as well as other location-based applications. 2 Features MediaTek MT3329 solution Support 66-channel GPS Fast TTFF at low signal level Support AGPS Up to 10 Hz update rate Capable of SBAS (WAAS, EGNOS, MSAS) Build-in micro battery to reserve system data for rapid satellite acquisition LED indicator for GPS fix or not fix Magnet for mounting on the car Skid resistant pad on the bottom Waterproof 2006 Page 1/14
