IAI's Fibre Optic Gyro Navigation System
IAI presented a new airborne navigation system called TNF-Tamam Navigation FOG (Fibre Optic Gyro) at Aero India. TNF is a lightweight, airborne navigation and attitude heading reference system (AHRS) for use in UAS, target drones, small aircraft, and helicopters.
It is also used for accurate targeting applications (inertial navigation system (INS)-on-Gimbal) in stabilized electro-optical/infrared (EO/IR) systems. The system uses Tamam’s FOG based inertial measurement unit (IMU) and a GPS receiver to provide precise integrated navigation solutions.
“The TNF is part of TAMAM’s advanced line of successful airborne navigation systems, and we are proud that it was chosen for leading UAV programs in Israel and overseas,” says Shaul Shahar, general manger of IAI’s TAMAM Division.
The TNF offers specification which includes heading accuracy of 0.5 degree, roll and pitch accuracies of 0.2 degree, and horizontal and altitude position accuracy of less than 3.3 feet — in DGPS mode.
