SkyTraq introduces S4554GNS, a high-performance low- power GLONASS/GPS receiver. The 88-channel receiver features industry leading 29 second cold start TTFF, -155dBm tracking, and -145dBm cold start sensitivity, offering best-in-class performance among GLONASS/GPS receivers on the market.
The S4554GNS is capable operating in GPS-only, GLONASS- only, and GLONASS + GPS modes. It is ideal for navigation and tracking applications requiring high- performance lower-cost GLONASS/GPS receiver.
Using dual GLONASS + GPS navigation satellite systems, S4554GNS offers better satellite signal availability performance. Dedicated search engine within S4554GNS is capable of performing 10 million time-frequency hypothesis testing per second, offering industry-leading signal acquisition performance for GLONASS and GPS signal.
Advanced track engine enables continuous locking of signals down to -155dBm, combining multipath detection and mitigation algorithm; it is capable of continuous accurate navigation in difficult urban canyon and deep foliage conditions.
S4554GNS comes in compact 45mm x 54mm form factor, with SMA connector and 20-pin header for easy plug-and-play usage. The operating temperature range is -40 ~ +85degC.
Volume delivery to customer begins in February 2010. Engineering sample, datasheet, reference design, and evaluation kits are available now.
