Using Long Range Video Downlinks from a Law Enforcement Helicopter

The Application of Long Range (up to 100 miles) Video Downlinks from a Law Enforcement Helicopter

A Long Range System (up to 100 miles) has a high gain antenna pod system on the aircraft and a high gain antenna system on the ground. Both antennas are automatically pointed with GPS coordinates. The aircraft system can only point at one receive site at a time so this eliminates the simultaneous transmission to the short range systems.

The GCA-4 Steerable pod system is the transmit side of the Long Range Microwave System. The GCA-4 pod contains a high gain antenna that is GPS pointed, a microwave transmitter, and a controller that aids in manually pointing the antenna and controlling frequencies of the transmitter. The pod is typically attached to the belly of the aircraft.
