SkyTraq Technology Inc. (Hsinchu, Taiwan) introduces state-of-art, all-in-one S2525DR8 GNSS dead-reckoning module, integrating MEMS sensor and interface logic on-board, enabling ease of use and fast time to market, ideal for road vehicles requiring high accuracy 100% positioning availability.
Based on SkyTraq’s latest Venus 8 multi-GNSS platform and using highest performance automotive grade XV-8100CB analog output gyroscope and 16bit differential ADC, the S2525DR8 offers best accuracy for both indoor and outdoor positioning. A 3D option adds barometric pressure sensor on-board, offering improved accuracy altitude reading and altitude change detection over accelerometer based scheme in 3D dead-reckoning. Another vehicle dynamics monitoring option adds accelerometer on-board, offering high accuracy vehicle acceleration monitoring for driver behavior characterization, accident reconstruction analysis, or trigger event recording.
The S2525DR8 is compact in size, measuring 25mm x 25mm. It contains level shifter on-board, capable of direct interface to vehicle odometer and forward/reverse signals ranging from 3V to 30V. The SPI interface pins on the module allow autonomous data logging to external SPI Flash memory device.
For high-performance vehicle navigation systems, S2525DR8 provides continuous navigation inside tunnels and underground parking lot without signal; highly accurate barometric altitude enables identification of which level the vehicle is on in a stacked multi-level high-way or a multi-story car park. For automatic vehicle locating or fleet management systems, location can be identified immediately after power on no matter it is outdoors or indoors under signal denied environment. S2525DR8 provides reliable, uninterrupted position, speed and heading information in challenging environments; it is suitable for demanding vehicle navigation and tracking applications requiring highest accuracy and availability.
S2525DR8 is in production, mass production manufacturing in ISO/TS 16949 automotive-certified factories. Evaluation kit, sample, datasheet, and reference design are available now. 3D option with barometric sensor and vehicle dynamics monitoring option with accelerometer will be available in latter half of Q1 2015.
