ORBCOMM Signs Agreement to Bring Satellite Data and Messaging Services to Russia, Belarus and Mongolia.

DULLES, Va.--(BUSINESS WIRE)--Dec. 22, 1998--ORBCOMM Global, L.P. (ORBCOMM), the first commercial provider of global low-Earth orbit (LEO) satellite data and messaging communications services, announced it has signed a service license agreement with GPSS (Gibraltar) Holdings Limited to provide two-way data and messaging communications to the territories of Russia, Belarus and Mongolia. ORBCOMM and GPSS expect to launch commercial service in these territories during 1999 through the Radio Engineering Corporation, the operating arm of GPSS in Russia.

Russia, Belarus and Mongolia will be served by the ORBCOMM satellite system and ground infrastructure that includes three gateway earth stations to be located in Moscow, Novosibirsk and Khabarovsk, as well as a gateway control center to be located in Moscow. The gateway earth stations and the gateway control center route messages to and from the satellites and their terrestrial destinations.

"The partnership of ORBCOMM and GPSS will enable customers for the first time to monitor, track and manage their business assets anywhere across this 17 million square kilometer territory," said Gerry Patrick Nash, Director of GPSS. "We are pleased to bring ORBCOMM service to a country with the geographic and economic significance of Russia and a population in excess of 150 million."

"Together with GPSS, we will introduce vitally needed communications solutions to people and businesses across Russia that are underserved by existing telecommunications alternatives," said Scott L. Webster, Chairman and Chief Executive Officer of ORBCOMM. "It's exciting to bring affordable, distance-insensitive data communications to a region that spans eleven time zones."
