Ground speed sensor AccoSat

True ground speed for Off-Highway Vehicles The MSO AccoSat is a speed sensor based on DGPS and a 3D accelerometer. By means of this sensor fusion the system reacts rapidly on acceleration (start and stop). This is especially advantageous for monitoring, control and closed-loop control on off-highway and agricultural machinery. The AccoSat system measures the forward speed by means of a triaxial accelero­meter and a DGPS receiver. AccoSat deploys a DGPS receiver optimized for speed measure­ment. The speed measure­ment - in contrary to detection on gear­box or wheel - is unaffected by effective tyre circum­ference, sinking-in and wheel slip. This is particulary advantegous for all applications needing an accurate speed signal for example for product application proportional to distance / area e.g. seeding, spraying and spreading. The AccoSat System does achieve high accuracy, dynamics and reliability of the speed measure­ment by means of a sensor fusion of a 3D accelero­meter with a DGPS receiver.The AccoSat provides for real time true ground speed for “outdoor / off - highway” applications for monitoring, control and closed loop control of machinery functions. Optionally DGPS positioning data (NMEA-0182) are output over a serial (RS232) interface.
