In 2001 Metrodata became involved with Unmanned Aerial Vehicle (UAV) Systems. We are not concerned with the specific Payload of the UAV, rather we are concerned with the Data Link characteristics that the Payload enforces on the UAV System.

Typically a UAV System will have the following elements:

• Air Vehicle
• Data Link
• Payload
• Mission Planning and Control Station (MPCS)
  

Ground Data Terminals Attract Hostile Fire

The Ground Data Terminal (GDT) is the ground portion of the data link. The GDT communicates with the UAV typically via microwave antenna that can provide Line-Of-Sight communications. Where this is not possible, satellite can be used.

In the past, the GDT would be co-located with the MPCS. Decisions can be made at the MPCS, as video, command, and telemetry data are all processed and displayed there. However, the RF emissions from the GDT can attract hostile fire.

So, where applicable the MPCS can be located remotely from the GDT, ensuring the safety of the Decision Makers and Controllers of the UAV. Typically this would be via Fiber Optic Cables, or if it was on an Air Base via the Bases ATM/Secure Network.
