AirSatOne Completes Test of Satcom Connectivity for BLOS Operations with COBHAM AVIATOR UAV 200 with GPS-Aided INS from Inertial Labs

AirSatOne (ASO), an Aviation Satellite Communication Service Provider, reported that its test using a COBHAM AVIATOR UAV 200 for Satcom connectivity and the Inertial Labs INS-P for Position, Heading, Pitch, Roll, and Velocity data has been successfully completed. The integration of the Inertial Labs INS-P provides rapid connectivity from static or dynamic initialization.

The AVIATOR UAV 200 was specifically designed for UAV’s to provide Satcom connectivity for Beyond Line of Sight (BLOS) operations which can be used to remotely pilot the aircraft and provide video feed for surveillance and situational awareness. Cobham designed the satcom terminal with a unique low gain, electronically steered antenna allowing full Inmarsat hemisphere coverage to 5° elevation, compared to other systems that typically offer coverage to 20° elevation. To achieve this, the satcom terminal needs external navigation data. To support this requirement, Inertial Labs equipped its INS-P with an AVIATOR UAV 200 compliant data format.

Upon UAV system’s initialization, the Inertial Labs INS-P precisely indicated 3D orientation, velocity as well as latitude and longitude utilizing its powerful tactical-grade IMU (1 deg/hr gyro), high precision GNSS receiver and gyro-compensated Fluxgate magnetic compass. During testing, connectivity remained stable with no interruptions while rotating 360°, during pitch variations of greater than ±45°, and roll values up to 45°. The resulting accuracy: Position <1 meter; Heading <0.2°; and Pitch/Roll <0.1°.

“We subjected the INS-P and Cobham AVIATOR UAV 200 to aggressive maneuvers in pitch, roll and heading/yaw and found that the combination allowed connectivity at extreme angles; including maintaining connectivity beyond 60 degrees pitch and roll. To further note, the INS-P came online quickly, even faster than our requirement,” stated Jo Kremsreiter, president at AirSatOne.
