Core Avionics Master Plan - NAVAIR - U.S. Navy

Core Avionics Master Plan 2011 Appendix A-22. Advance Research and Technology Development.Reduced Size Antennas. (2013-2015) Current antennas available to implementWideband SATCOM on many air platforms are too costly and difficult to install. In orderto reduce the integration cost and complexity, industry is researching smaller antennasand other conformal solutions in order to meet the system link-budget requirements.Smaller antennas would also allow integration onto non-central areas of air platformswhere there are significant space restrictions. These technologies are still limited toinnovative research and demonstration phases.3. Funded Enhancements and Potential Pursuits.High Data Rate Aviation Terminal (HDRAT). (2017) HDRAT will provide for secureKa/Ku high data rate satellite links (over commercial and government owned assets)and line-of-sight communications supporting Airborne Intelligence, Surveillance, andReconnaissance (AISR) platforms. It will provide AISR platforms with antenna solutions,modem assemblies, and the appropriate waveforms capable of supporting highresolution sensor data and C2 links at speeds up to 274 Mbps (platform and missiondependent).E. High Frequency (HF).1. Current capabilities.HF radios operate between 3 and 30 MHz and are still maintained on platforms thatcan accommodate the antennas for back-up BLOS communications. HF commonlyuses ionosphere propagation of radio waves to span BLOS distances. HF datatransmissions typically operate at user data rates 1200 to 2400 bps with advancedmodem waveforms capable of 9600 bps within 3 kHz channels. HF amplifiers typicallytransmit at 20 to 150 Watts for portable units and up to 2000 Watts for high powerstations. HF usage enables ad hoc connectivity (no prior access permissions or timeslot coordination required).HF - Automatic Link Establishment (HF-ALE) was developed based on the militarystandard for Interoperability and Performance Standards for Medium and HighFrequency Radio Systems (MIL-STD-188-141A and -141B). HF-ALE enables the radioto initiate a circuit between itself and another HF radio station or network of stationsalong with automated frequency selection for the connection. ALE also contains NATOStandardization Agreement (STANAG) 5066, which specifies protocols which separateapplication data and modem/radio level information.HF internet Protocol (HFIP or HF-IP) is usually associated with ALE and HF radiodata communications. HFIP provides protocol layers enabling internet file transfer, chat,web, or email.2. Funded Enhancements and Potential Pursuits.Increased Throughput (Wideband HF). (2016) Wideband HF is a waveform indevelopment that will be able to offer users higher data rates over HF. Testing wasconcluded in December of 2009 and interoperability testing was concluded in March of2010. MIL-STD-188-110C was drafted and ready for DOD approval in August of 2010.A-2 Information Exchange 15
