Nå er det mange som har demonstrert tilsvarende, og det er spørsmål om hvilke standarder sertifiserende myndigheter går for. (Red.)
Satcom Tested for Civil UAS Beyond-line-of-sight Ops
Satcom
service provider AirSatOne (ASO) has completed testing Cobham’s Aviator UAV 200
satcom terminal with Inertial Labs’ INS-P GPS-aided inertial navigation
system. The UAV 200 was specifically designed to provide UASs with satcom
connectivity for beyond-line-of-sight (BLOS) operations, which can be used for
remote piloting and to provide video feed for surveillance and situational
awareness.
The
Cobham terminal is designed with a low-gain, electronically-steered antenna that
allows for Inmarsat hemisphere coverage to 5 degrees elevation by using external
navigation data. To support this, Inertial Labs equipped its INS-P with a UAV
200-compliant data format. Upon UAV system’s initialization, the Inertial Labs
INS-P indicated 3D orientation, velocity as well as latitude and longitude using
its IMU (1 deg/hr gyro), precision GNSS receiver and gyro-compensated Fluxgate
magnetic compass.
During
testing, Inertial Labs reported that connectivity remained stable with no
interruptions while rotating 360 degrees, during pitch variations of greater
than plus or minus 45 degrees, and roll values up to 45 degrees. Reported
accuracy was position within one meter, heading variation less than 0.2 degrees,
and pitch and roll variation of less than one degree.
