Cobham, which produces specialized communications, security and surveillance products, introduces a high definition (HD), dual stream video transmitter called the Messenger 2 Transmitter Enhanced (M2TE) for use on unmanned aerial vehicles (UAVs).

The M2TE is a miniature video transmitter with AVC/H.264 video encoding for dual input HD or standard definition (SD) video and data programs, Cobham says. The technology supports any combination of HD or SD video using HDSDI, SDI or composite camera inputs from 1080p 60 fps down to 480i/576i (NTSC or Pal), the company adds.

“The M2TE transmitter provides a bird’s eye view in real time for ground forces,” said Steve Schaefer, Cobham Tactical Communications and Surveillance’s vice president. “It supports two video streams over one wireless video link with extremely low latency, or delay, giving it true tactical capability.”

The coded orthogonal frequency division multiplexing (COFDM) modulation makes the link robust over water, just above the horizon and even some non line-of-site, the company says. Those conditions can be a problem for signal carrier links such as FM, DDL and CDL. Radio frequency bands are available from 0.9 to 7 gigahertz in bands with AES-128/256 encryption. Control is provided via the local panel or remote local area network (LAN) web server or serial interface.

In addition, the M2TE’s small size (3.6 inches by 3.12 inches by 0.75 inches), light weight (10 ounces) and low power draw (12 watts), allow it to support small UAV’s and have a range of up to 0 miles on L-Band with a dual or single video feed and simple patch antennas at the receiver. System delay (or “latency”) is 44 ms end to end ensuring the operator sees video as it happens in real time. With the addition of our miniature VEPA 2W RF Power Amplifier, the range can reach up to 30 miles with dual or single video feed, the company says. Other combinations of compatible amplifiers and antennas can be utilized to push the range out beyond 100 miles.
