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.

Chairman Touts Benefits of Satellite Phones in Disaster Zones
By 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?
RADIO
Dependant on terrestrial infrastructure
CELLULAR
Dependant on terrestrial infrastructure
SATELLITE

MEMA Comments
Robert R. Latham Jr, Executive Director
Mississippi 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 Mississippi’s 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.
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
Multiple Crossband Interface
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

MSV’s 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
