Mobile User Objective System (MUOS)
����� Targeted to be ported to JTRS HMS manpack
and AMF radio sets. Designed to SCA compliance.
����� Provides ATH and OTM point-to-point, point-tomultipoint,
netted, and broadcast communication
networks for voice and data services between
geographically dispersed ground, maritime, and
airborne users. Replacement for the Navy’s UFO
constellation, while maintaining backwards
compatibility with legacy UHF terminals.
����� Supports GIG/Teleport access for voice and IP
data services such as DSN, SIPRNET, NIPRNET,
JWICS, CENTRIX.
����� Network Throughput:
* 40 Mbps of total capacity
* 2.4Kbps to 384 Kbps per user
* Can connect up to 1997 terminals
simultaneously.
����� Provides voice capability using the MELP-E and
G.729 A/B vocoders.
����� Uses frequency bands UHF, Ka, and S Bands.
UHF SATCOM Integrated Waveform (IW)
����� Targeted to be ported to JTRS radio sets and
designed to SCA compliance.
����� Upgrade to the UHF SATCOM DAMA waveform
designed to add additional UHF capacity for users
until MUOS is in place. Designed on new DISA
MIL-STD’s 188-181C, 182B and 183B.
����� IW will more than double the throughput of 5kHz
and 25-kHz DAMA channels over the existing
DAMA standards.
����� A 25kHz channel will now support up to 20 at
2.4kbps networks at mixed modulation rates as
opposed to the previous five networks in the old
standard.
����� A 5 kHz IW UHF channel will support similar
rates as the 25 kHz channel.
����� Provides narrowband, low data rate services,
i.e. data/messaging, facsimile, paging, and nettedvoice
communications requirements, to
����� Range: BLOS Satellite to BLOS satellite via
ground segment achieving global coverage; 65N
65S.
����� Uses High Assurance IP Encryption (HAIPE) for
DISN services (SIPR/NIPR) and DSN (PSTN)
����� Supports IPv4/v6.
����� Channel Bandwidth: Spreads power across a 5-
MHz bandwidth allowing higher signal power levels
to users than permitted by legacy narrowband
systems. WCDMA also uses adaptive power
control to minimize interference and maximize
system capacity for user terminals. Supports
bandwidth on demand and assured
communication services for deployed users.
����� MUOS waveform is a Direct Sequence Spread
Spectrum (DSSS) WCDMA waveform leveraged
from 3G commercial cellular technologies modified
to meet MUOS requirements.
����� Frequency Re-use: Sixteen beam design allows
significant frequency reuse.
communications-on-the-move, mobile, and static
operational elements.
����� IW defines a single Demand Access method
applicable to both 5- and 25-kHz channels, reducing
the number of orderwire messages from 96 to only
30. This serves to simplify radio operation.
����� IW provides backward interoperability in all modes,
rates, and formats with today’s DASA and DAMA
services as defined in MIL-STD-188-183 and MIL-
STD-188-183A.
����� IW DAMA offers improved TDMA, time slot / burst
rate efficiencies, and can now support a 56 kbps
data circuit over the traditional DAMA 2.4kbps.
����� IW does not negatively affect MELP voice coding.
����� Supports up to 56 kbps PSC5C/D, ARC231, and
AN/PRC117F.
����� Projected fielding 3rd Quarter FY08.
