Globalstar Signs Agreement to Increase Satellite Messaging Capacity by 10 Times and Further Expand Simplex Data Coverage

Radyne Corporation's AeroAstro Upgrades to Increase Data Receiver Sensitivity by 40 Percent and Further Enhance Highly Reliable Satellite Simplex Data Services


MILPITAS, Calif., Oct. 18, 2007 (PRIME NEWSWIRE) -- Globalstar, Inc. (Nasdaq:GSAT), a leading provider of mobile satellite voice and data services to businesses, governments, and individuals, today announced that Radyne Corporation business unit AeroAstro will supply Globalstar with the necessary network upgrades that will enhance both the receiver sensitivity and the overall customer messaging capacity of the Globalstar Simplex data network.

According to the recently signed agreement, AeroAstro will provide Globalstar with the ground network upgrades needed to expand the current subscriber messaging capacity of the Globalstar Simplex data network by 10 times and increase receiver sensitivity of the network by up to 40 percent. Increased receiver sensitivity will further expand the geographic coverage area of Globalstar's gateway earth stations and is expected to improve Simplex message transmission reliability, which already exceeds 99 percent in the gateways' primary coverage area. Deliveries of the necessary upgrades are scheduled to begin in early 2008.

Globalstar's highly reliable Simplex data network is used to support a variety of aviation flight-following, emergency asset, fleet and personal tracking applications. Simplex data modem integrated solutions are also used for a number of remote monitoring and alarm applications, both within and beyond the reach of traditional wireless and terrestrial infrastructure. Information such as GPS location co-ordinates, remote status and other sensor information can be reliably sent to customers using the Globalstar Simplex network.

"Asset tracking, personal tracking and remote data monitoring are three of our most vital core customer segments and we expect the enhancements resulting from this agreement with AeroAstro will provide customers with even better service and increased messaging capacity," said Jay Monroe, Chairman and CEO of Globalstar, Inc. Mr. Monroe added, "As we move towards transitioning to our second-generation constellation, Simplex data is expected to grow in importance. Therefore, we are committing to continue enhancing our global Simplex data network. This agreement demonstrates our resolve to encourage our product integrators and manufacturers to continue their innovative product design initiatives."

Earlier this year Globalstar subsidiary SPOT Inc. unveiled the new SPOT satellite messenger. SPOT integrates the location functionality of a GPS chipset with the global messaging capability offered by a Simplex data modem into an affordable and revolutionary consumer based emergency communications and tracking product.

The L-band uplink to Globalstar's constellation of satellites is completely stable in supporting all Simplex data satellite products and asset tracking services including SPOT.
