Ellipse-D Dual Antenna GNSS/INS is a compact inertial navigation system with an integrated dual-antenna RTK GNSS receiver for accurate heading and navigation. It provides roll, pitch, heading, heave and navigation data, combining GNSS and inertial inputs for demanding unmanned systems and payloads.
The system includes a MEMS-based IMU and an enhanced Extended Kalman Filter that fuses inertial and GNSS data, with odometer and RTK corrections available as aiding inputs. It provides very low noise gyroscopes, differential corrections, post-processing support, odometer connectivity and a 200 Hz output rate, with availability in an IP68 enclosure or PCB-mounted OEM version.
Ellipse-D is ideal for a range of defense applications, including precision pointing and stabilization, UAV inertial navigation, loitering munitions, unmanned ground vehicles and unmanned surface vehicles. Its dual-antenna heading capability helps address applications where magnetic fields are unreliable or where accurate heading is required in low-dynamic conditions, supporting defense navigation, stabilization and platform control.
