Overview Modulestek GPS module MG-ST01 is a high sensitivity ultra low power consumption cost efficient, compact size; plug & play GPS module board designed for a broad spectrum of OEM system applications. This product is based on the SkyTraq GPS technology and it will track up to 44 satellites at a time while providing fast time-to-first-fix. Its far reaching capability meets the sensitivity & accuracy requirements of car navigation as well as other location-based applications, such as AVL system. Handheld navigator, PDAs, Wrist Watches, Personal Locators, Toll collection, Fleet Management, pocket PC, or any battery operated navigation system. The MG-ST01 design utilizes the latest surface mount technology and high level circuit integration to achieve superior performance while minimizing dimension and power consumption. 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 module communicates with application system via RS232 (TTL level) with NMEA0183 protocol. 1.2. Main Feature Built-in SkyTraq chipset. 44 channels "All-in-View" tracking. Hot start < 1sec under open sky Cold/Warm/Hot start time: 30/28/1 sec. (average) Superior sensitivity: -159 dBm for Superior urban canyon. Support A-GPS function. Reacquisition time: 0.1 sec. Ultra Low power consumption.(<40mA) Support of SBAS(WAAS / EGNOS) satellites for navigation Compact Size: 24.0x18.0x2.0mm, Easy integration into hand-held device. www.modulestek.com 4 Key Modules For Your Success 2.
