User Manual

The new SkymasterTX (SKTX) is a lightweight, full-featured digital COFDM video downlink transmitter built to address the unique requirements of aircraft downlink operation. The chassis design features either horizontal or vertical ARINC mounting. All of the connections and controls have been lo-cated on one side of the unit. This allows the SkymasterTX to be removed from one aircraft and installed in another with ease. A unique feature of the SkymasterTX is a built-in GPS receiver. This allows aircraft position data to be downlinked to the command center for display on a moving map system. This feature allows rapid location of the aircraft.The SkymasterTX can operate in a wide variety of bands delivering High Denition and Standard Denition video resolutions. The SkymasterTX can output up to 8W of RF power extending and improving link reliability. The SkymasterTX features COFDM digital modulation. COFDM modulation is unaffected by multipath – unlike single-carrier modulation formats such as FM, CDL or QAM.The SkymasterTX has a built-in H.264 (MPEG-4) encoder or optional MPEG-2 encoder. MPEG-4 encoding is the latest encoding method. It requires 50% less bit-rate over MPEG-2 improving the reliability of the transmission even more. MPEG-4 also allows for the transmitting of High Denition video without sacricing performance. IMT has taken great care with the design of the internal H.264 encoder. It has been designed with video quality as its cornerstone. The quality of the encoding rivals that of full-featured rack mounted encoders. Knowing that security of the video is critical, the SkymasterTX features the latest in AES 128 and 256 encryption. This feature can be enabled or disabled very easily allowing the mode to be selected depending on the mission requirements. To ensure interoperability between vendors we also conform to BCRYPT, a published, non-proprietary standard.The front panel LCD and a Remote Control user interface allow for quick control of preset selection, standby mode, and encryption mode. For ad-vanced functions such as changing frequency plans, AES encryption keys, or unit naming, an easy-to-use administration software package is sup-plied. Conguration is exible with 16 or more different presets available.HD / SD COFDMAircraft TransmitterSkymaStertXFeatureS:n Proven interoperable SD and HD encodingn 8W RF TX output powern Standard bands include 2GHz, 4.5 GHz and 6.5GHzn MPEG-4 Part-10/H.264n Optimized size and weight for aircraftn Multiple ARINC mounting optionsn Superior broadcast quality videon Video, audio, data and telemetryn Front panel LCD screen and LED alarmsn ASI multiplexingn GPS receivern AES encryption (BCRYPT)n 16 or more user congurable presets OptiOnS:n Narrow band 1.25 MHz/2.5 MHz COFDMn Second MPEG-2 or MPEG-4 encoder *n IP streaming input *acceSSOrieS:n ACCESS remote controln ARINC mounting trayn GPS antenna
