Military Satellite Communications
Military satellite communications (MILSATCOM) systems include those systems owned or leased and
operated by DoD and those commercial satellite communications (SATCOM) services used by DoD. The
basic elements of satellite communications are a space segment, a control segment, and a terminal
segment (air, ship, and ground). An implementation of a typical satellite link will require the use of
satellite terminals, a user communications extension, and military or commercial satellite resources. For
information on MILSATCOM standards go to: https://disain.disa.mil/sisc/. A brief description of the
categories and types of SATCOM links and standards follows.
The basic categories of SATCOM are:
• Narrow Bandwidth (NB): = 64 kbps
• Unprotected: Not Anti-Jam or Low Probability of Intercept
• Protected: AJ and/or LPI
• Commercial: Non-government owned or operated
• Government/Military Government owned and operated
Military Ultra High Frequency (UHF) (Narrow Bandwidth)
� NB, Military service
� Transponded 5 and 25 kHz channels
� Complete transition to DAMA based services is mandated, and in process
� For 5-kHz or 25-kHz single-channel access service supporting the transmission of either voice or
data: MIL-STD-188-181B, Interoperability Standard for Single Access 5-kHz and 25-kHz UHF
Satellite Communications Channels, 20 March 1999.
� For 5-kHz Demand Assigned Multiple Access (DAMA) service, supporting the transmission of data
at 75 to 2400 bps and digitized voice at 2400 bps: MIL-STD-188-182A, Interoperability Standard for
5-kHz UHF DAMA Terminal Waveform, 31 March 1997, with Notice of Change 1, 9 September
1998; and Notice of Change 2, 22 January 1999.
� For 25-kHz Time Division Multiple Access (TDMA)/DAMA service, supporting the transmission of
voice at 2,400, 4,800, or 16,000 bps and data at rates of 75 to 16,000 bps: MIL-STD-188-183A,
Interoperability Standard for 25-kHz TDMA/DAMA Terminal Waveform, 20 March 1998, with
Notice of Change 1, 9 September 1998.
� For data controllers operating over single-access 5-kHz and 25-kHz UHF SATCOM channels: MIL-
STD-188-184, Interoperability and Performance Standard for the Data Control Waveform, 20 August
1993, with Notice of Change 1, 9 September 1998. This standard describes a robust link protocol that
can transfer error-free data efficiently and effectively over channels that have high error rates.
� For MILSATCOM equipment that control access to DAMA UHF 5-kHz and 25-kHz MILSATCOM
channels: MIL-STD-188-185, DoD Interface Standard, Interoperability of UHF MILSATCOM
DAMA Control System, 29 May 1996, with Notice of Change 1, 1 December 1997; and Notice of
Change 2, 9 September 1998.
Military Wide Bandwidth, Unprotected
� The standard waveform is described in MIL-STD-188-165A, with revision B currently in staffing. It
supports data rates from 64 kbps to 155 Mbps. This specification is compliant with the requirements
for use of commercial WB systems.
� The Earth Terminal specification is MIL-STD-188-164, which describes ground, air, and surface
terminal parameters.
