SBG SYSTEMS ELLIPSE-D MINIATURE DUAL GPS INS

Ellipse-D is the smallest Inertial Navigation System (INS) integrating a Dual-antenna, multi-band GNSS receiver, capable of delivering precise heading as well as centimeter-level position accuracy in the most challenging GNSS conditions. It provides attitude, heading, heave as well as navigation outputs. Ellipse-D is an ideal choice for magnetic denied applications and can operate in all dynamic conditions with optimal performance. It features 0.05° Roll and Pitch (RTK), Post-processing with Qinertia PPK Software. The Ellipse-D is equipped with state-of-the-art MEMS sensors, especially very low noise gyroscopes. The Ellipse-D enables a 9-axis IMU sensor, a dual-antenna RTK GNSS module offering one-centimeter accuracy, with a 64-bit microprocessor for processing data. The Ellipse-D is also equipped with high-quality accelerometers with Internal FIR filters coupled with Coning & Sculling integrals to provide efficient vibration rejection. Additional features includes a temperature sensor, pressure sensor, and odometer input.
