For Immediate Release



            NEW GENERATION OF COMMUNICATIONS SERVICES TO EMERGE WITH
              TODAY'S FCC ACTION; MSV MOVES AHEAD ON VISION FOR MSS

Reston, Va., - February 10, 2005 - Mobile Satellite Ventures (MSV) announced
today that the Federal Communications Commission (FCC) finalized a comprehensive
set of rules following a detailed multi-year process for the use of ancillary
terrestrial component (ATC) with mobile satellite services (MSS). By today's
decision, the FCC expanded the technical and operational flexibility of ATC
services; specifically, the new FCC rules allow for greater capacity in both the
uplink and downlink directions, thereby assuring robust high speed service.

"We are thrilled by the FCC's decisive action in approving greater flexibility
for ATC mobile communications. This architecture holds great promise for all
Americans, but offers particular benefits to residents of rural areas and those
federal, state and local agencies that are charged with protecting public
health, safety and security," Alexander H. Good, Vice Chairman and CEO of MSV,
said. "The Commission has shown strong leadership in conducting a detailed
review and seeing this important effort through to this final result."

MSV is the leader in ATC technology development with numerous patents and patent
applications for virtually every element of ATC. The very strong position
created by its recent $230 million equity funding announcement enables MSV to
aggressively pursue its ATC development.

"The FCC made communications history today with its decision to provide the
greater flexibility that is critical to creating a robust mobile satellite
industry. Our customers are anxiously awaiting this powerful network that will
deliver the considerable benefits that are unique to our hybrid
satellite/terrestrial service," continued Mr. Good.

The key advantages of implementing ATC are that it allows ubiquitous,
interoperability and redundancy that is vital to homeland security applications.
The use of mainstream interfaces means that services and applications developed
by the wireless industry become available to everyone - finally wireless
everywhere.

"Our region's hospitals, EMS agencies, rescue teams and emergency management
personnel recognize the integration of an MSS network with ATC offers one of the
best mechanisms to ensure a robust and highly functional, wide-spread
interoperability solution that helps us address the needs for communications for
all hazards and risks, including homeland security requirements," said Eric
Epley, Executive Director, Southwest Texas Regional Advisory Council for Trauma.

According to Andrea Seastrand, Executive Director of the California Space
Authority, "The innovative hybrid cellular/satellite network proposed by MSV is
the most promising solution to the varied communications needs of those on the
front line of homeland security. For the first time, a single device with
ubiquitous service will create a robust network capable of providing instant
voice, information exchange and imaging to all first responders."
