SkyTraq Technology Inc., a fabless GNSS positioning technology company, has introduced their S1722DR8 GNSS dead-reckoning receiver which integrates 3-axis gyroscope/accelerometer and barometric pressure sensor with GNSS receiver.

Using wheel/speed data from vehicle to perform sensor-fused solution, S1722DR8 achieves 100 percent coverage; perfect for vehicles applications requiring highest performance, reliable, uninterrupted positioning. S1722DR8 can be flexibly mounted in any orientation, no longer required to be placed horizontally as in conventional DR solutions using single-axis gyroscope. The auto-calibration feature of S1722DR8 greatly simplifies installation procedure; very short calibration time upon first use also much improves user experience. The on-board barometric pressure sensor provides highly accuracy altitude information, useful for differentiating floor level of multi-story parking garage or stacked highway.

The S1722DR8 is compact in size, measuring 17mm x 22mm. It offers continuous navigation even in GPS signal denied environments such as tunnels or underground parking lot. Augmented by gyroscope and accelerometer sensor data, it is also ideal for vehicle insurance accident reconstruction applications.

S1722DR8 engineering sample, evaluation kit, and datasheet are available in May. Volume delivery to customers begins in June 2016. S1722DR8 is manufactured in ISO/TS 16949 automotive-certified factory.
