GEO LEO
Satellites in LEO are just 200 - 500 miles above
the earth.
Because they orbit so close to Earth, they must
travel very fast so gravity won't pull them back
into the atmosphere. Satellites in LEO speed
along at 17,000 miles per hour . They can circle
Earth in about 90 minutes.

FCC View

• FCC Chairman Touts Benefits of Satellite Phones
  in Disaster ZonesBy MISSY FREDERICK Space News
  Staff Writer
• WASHINGTON The chairman of the U.S. Federal
  Communications Commission (FCC) told lawmakers
  Sept. 22 that satellite technology has a key role
  to play in disaster relief efforts due to the
  vulnerability of terrestrial communications
  infrastructure.
• If we learned anything from Hurricane Katrina,
  it is that we cannot rely solely on terrestrial
  communications, Kevin Martin told members of the
  Senate Commerce, Science and Transportation
  Committee. When radio towers are knocked down,
  satellite communications are, in some instances,
  the most effective means of communicating.

What are the options?
Utilize older VHF radios ( Presumes availability
of equipment ) Get a COW in place (Takes time
and restricted to installed frequencies) Bring
in a command vehicle (Takes time and restricted
to installed frequencies) Switch over to back up
communications (Best option but assumes back up
communications strategy)

What are the back up options?

MEMA Comments
Robert R. Latham Jr, Executive Director Mississipp
i Emergency Management Agency Testimony Before
the House Select Bipartisan Committee to
Investigate the Preparation for and Response to
Hurricane Katrina, December 7,2005 The entire
communication infrastructure of Mississippis
Gulf Coast was destroyed and systems in many
other parts of our state were rendered inoperable
while systems that were operational were
overloaded.  While we have invested millions of
dollars in communication inoperability, the issue
after Katrina was operability.  The primary means
of communication for MEMA and the Mississippi
Department of Wildlife, Fisheries and Parks is
satellite, the only communication system that was
operational during the days after landfall.

GPS Tracking Service

• Push-to-Talk GPS Position is transmitted when
  user PTTs
• On Demand Polling A dispatcher can Poll a
  radio at any time.

The MSAT-G2 radio will transmit GPS location to
the MSV hub, where it will be available to
customers via the internet on a subscription
basis.
28
Interoperability
Communications is about the successful and
efficient transmission of secure and relevant
information/data to required parties when
needed. INTEROPERABILITY is about enabling such
communications
29
Multiple Crossband Interface
30
Crossbanding as a solution

• Allows existing equipment to function
• Legacy equipment will continue for many years
• Enables speedy deployment
• Allows functional groups retain operational
  independence
• Enables interoperation between radio, cell and
  satellite
• Satellite enables connectivity from anywhere
  back to HQ

MSVs Hybrid Vision for the Future

• To create an integrated, hybrid wireless system
  that enables
• Truly ubiquitous communications services
• Through devices that are virtually
  indistinguishable from other wireless devices
• Using terrestrial and satellite communications
  infrastructures

MSV is in the process of implementing this vision
36
Satellite as Redundant Platform

• If terrestrial infrastructure is not available or
  in the case of an emergency
• Satellite capacity can be dynamically allocated
  to a specific area
• Satellite system can be preempted for government
  use by Public Safety Operator Priority Access
• Communication still ensured throughout North
  America

Central Points of Access/Control
Emergency Towers are Down
37
Public Safety Security Benefits

• An integrated hybrid wireless L-Band network
• Device transparency, form factor and cost
• Service rates comparable to traditional
  terrestrial services
• Seamless North American coverage
• True network interoperability
• Priority service capabilities
