DMD-2050E MIL-STD-188-165A/STANAG 4486

The DMD2050E Satellite Modem is designed to comply with the widest possible range of U.S. Government and commercial standards and is compatible with the largest number of satellite modems in the industry. It is fully compliant with MIL-STD-188-165A (all terminal types), fully complies with STANAG 4486 Edition 3, as well as the IESS-308, IESS-309, IESS-310 & IESS–315 commercial standards.

The DMD2050E provides highly advanced and bandwidth efficient forward error correction (FEC). Advanced FEC options include Low Density Parity Check (LDPC), Turbo Product Codes (TPCs) and 165B Turbo Codes. Legacy support for Viterbi, Trellis, Concatenated Viterbi Reed-Solomon, and Sequential FEC are also included. A complete range of modulation types is supported including BPSK, QPSK, OQPSK, 8PSK, 8-QAM, 16-QAM and 16APSK.

Advanced FEC and modulation capabilities are integrated with the revolutionary DoubleTalkⓇ Carrier-in-CarrierⓇ bandwidth compression allowing for maximum state-of-the-art performance under all conditions. This combination of advanced technologies enables multidimensional optimization, allowing satellite communications users to:

  • Minimize required satellite bandwidth
  • Maximize throughput without using additional transponder resources
  • Maximize availability (margin) without using additional transponder resources
  • Enable use of a smaller BUC/HPA and/or antenna
  • Or, a combination of the above to meet specific mission needs
