GNSS dead-reckoning receiver offered by SkyTraq

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

Using wheel/speed data from vehicle to perform sensor-fused solution, S1722DR8 achieves 100-percent coverage. It is designed for vehicles applications requiring high performance and reliable uninterrupted positioning.

The S1722DR8 can be flexibly mounted in any orientation, and does not have to be placed horizontally as in conventional dead-reckoning solutions using single-axis gyroscope. The auto-calibration feature of S1722DR8 greatly simplifies installation procedure; the short calibration time upon first use also improves user experience.

The on-board barometric pressure sensor provides highly accuracy altitude information, useful for differentiating floor levels of multi-story parking garages or stacked highways.

The S1722DR8 is compact, measuring 17 x 22 millimeters. 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 designed for vehicle insurance accident-reconstruction applications.

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