SENSOR FUSION OF 3D ACCELEROMETER AND GNSS FOR TRUE GROUND SPEED MEASUREMENT AND POSITIONING The AccoSat system combines the advantages of GNSS-based speed measurement with the high dynamics of a 3D accelerometer. Thus a reliable and fast true ground speed measurement is achieved. In addition to a “RADAR-compatible” pulse signal GNSS positioning data (NMEA-0183) are optionally output. Speed measurement: • with high dynamics and accuracy • with fast detection of start, stop and acceleration • no calibration, plug and play • dead reckoning of speed signal on short GNSS outages e.g. in tunnels • pulse output signal proportional to speed • “RADAR - compatible” pulse output • easy mounting, magnet plate optionally

AccoSat speed sensor The AccoSat system measures the true speed of a vehicle over ground using an acceleration sensor and GNSS receiver. The GNSS receiver has particularly strong reception and is optimized for speed measurement. Unlike measurements taken from the transmission or wheel, this measurement is not affected by effective wheel circumference, sinking, or wheel slip. This is particularly advantageous for all applications that require an accurate speed signal, e.g., for distance- or area-proportional application such as sowing, fertilizing, and spraying. The AccoSat sensor system is characterized...
