SkyTraq Introduces Industry Leading Ultra Low Power AGPS Receiver
Hsinchu, Taiwan (SPX) Nov 11, 2008 SkyTraq has introduced the Venus634LPx GPS receiver, a higher-performance lower-power successor of its Venus634LP all-in-one GPS receiver. The new Venus634LPx features improved cold start sensitivity of -148dBm, better tracking sensitivity of -161dBm, lower full-power tracking current of 23mA, and smaller LGA44 package of 10mm x 10mm x 1.1mm. The device contains all the necessary components of a GPS receiver, including GPS RF front-end, 65 channel GPS/AGPS baseband processor, 0.5ppm TCXO, RTC crystal, LDO regulator, and passive components. A complete GPS receiver requires only antenna, Venus634LPx, and few external passive components. Featuring industry-leading 29 second cold start TTFF, -161dBm tracking sensitivity, and 23mA current consumption, the highly integrated ROM-based Venus634LPx GPS receiver enables lowest cost of embedding location awareness into portable applications without compromising size, performance, and battery life. It is compatible with both active and passive antenna. Dedicated signal parameter search engine within Venus634LPx is capable of performing 8 million time-frequency hypothesis testing per second, offering ultra-fast TTFF performance. Advanced track engine allows continuous navigation in harsh environments such as urban canyon and under deep foliage. Venus634LPx supports SkyTraq's available server-assisted PromptFix AGPS, offering 7-day AGPS data aiding per server connection. It will also be compatible with SkyTraq's self-assisted PromptFixII AGPS, to be released in Q1 2009 for applications with ample host processing power and memories. Venus634FLPx, flash version of Venus634LPx suitable for customized firmware, is also housed in a pin-compatible 10mm x 10mm x 1.1mm LGA44 package. Both devices has operating temperature range of -30 ~ +85degC. Related Links SkyTraq GPS Applications, Technology and Suppliers
