Benefits
Commercial SATCOM

• Capacity to augment MILSATCOM
• Spectral diversity enhances SATCOM robustness
  ---particularly important in harsh EMI
  environment of naval platforms
• Worldwide coverage
• Reliability and maintainability
• Surge capacity which is accessible and flexible
• Rapid response to new/changing mission
  requirements
• Assured access
• Bandwidth (BW) optimization

Limitations

• Satellite leases are more expensive
• Radio Frequency Interference (RFI)
• Satellites are not protected and are subject to
  jamming
• Fixed Satellite Service (FSS) systems operate on
  a not-to-interfere basis (NIB)
• We must be responsible citizens of the commercial
  SATCOM world
• Protection factors being addressed by DoD
  protection working group

7
Navy SATCOM Strategy
Way Ahead Navys intent for the future is to
continue reliance on MILSATCOM. We plan to
maintain the ability to use Commercial SATCOM as
an augmentation to MILSATCOM.

ADNS Fielding Timeline
EBEM Fielding Timeline

• Commercial requirements are being worked with
  Fleet to determine the appropriate level type
  of MILSATCOM augmentation needed
• Assumes Typical DDG capability as EBEM FY08,
  ADNS Inc III FY10, and NMT in FY13
• WGS IOC is FY09 (assume ¼ data rate with DSCS)
  AEHF IOC is FY10 (assume ¼ data rate with Milstar)

Conclusion

• Navy plans to continue to use Commercial SATCOM
  to augment complement MILSATCOM capabilities
• Multiple challenges to fielding SATCOM solutions
  in a Navy shipboard environment
• PEO C4I encourages continued Industry partnership
  to explore the best overall end-to-end solution
  for Navys SATCOM requirements
