Surveillance: quality of video imagery relayed using the Inmarsat Swiftbroadband contested service

• The InView UAV uses satellite communications (“satcoms”) in beyond Visual Line Of Sight (BVLOS) applications
• Relatively low bit rate between 70 kBit/sec and 170 kBit/sec, depends on number of people sharing the same spot beam

at the time (the total 34 MHz bandwidth is shared, or “contested”, by the users within the spot beam)

Surveillance: quality of video imagery relayed using the Inmarsat Swiftbroadband contested service

• Relayed thermal video imagery example
• Suitable to detect people and vehicles
• Insufficient resolution to identify objects

Automated object detection

Rather than have one payload operator per unmanned aircraft in a formation of UAVs, we use machine intelligence to interpret sensor data in real time on each UAV to detect statistically significant anomalies, and then only relay information when an anomaly is detected – so making good use of a limited bandwidth communication link.

Development of precision UAV landing technology to enable automatic cargo attachment capability

We are developing RF beacon detection for coarse cargo acquisition, using a Monopulse Phase Comparator circuit based on four patch antennas, shown below, with four output signals from the underside, analog, microwave circuitry. Each signal output is derived from a specific combination of the signals from each of the four microstrip patch antennas. The elevation and azimuthal deviation signals from boresight are externally normalised to the SUM output signal.

Development of precision UAV landing technology to enable automatic cargo attachment capability

We are developing an automatic optical registration technology to complement the microwave beacon detection to enable precision UAV landing to enable automated pick up of a cargo from a remote, BVLOS, location.
