The Venus816 is a low-cost high-performance single-chip GPS receiver targeting camera, cellular handset, MID, mobile gaming, fitness, and asset tracking applications. It is a complete ROM-based stand-alone GPS chipset offering very low power consumption, high sensitivity, best in class signal acquisition and time-to-first-fix performance.

Venus816 single-chip GPS receiver features low cascaded RF section noise figure of 1.2dB, capable of working with passive and active antenna directly, eliminating the need of additional external LNA when using passive antenna, offering significant saving for cost-sensitive high-volume applications. It requires low external component count and small PCB footprint.

Dedicated massive-correlator signal parameter search engine within the baseband enables rapid search of all the available satellites and acquisition of very weak signal. An advanced track engine allows weak signal tracking and positioning in harsh environments such as urban canyons and under deep foliage.

Enhanced ephemeris decoding algorithm reduces TTFF time under fluctuating weak signal reception environments. Highly optimized navigation algorithm offers continuous and reliable navigation under most difficult environments.

With exceptional GPS signal acquisition and TTFF speed, the Venus816 GPS receiver has very low average power consumption for locate on demand type of applications.
