LONDON โ€”


Mobile satellite telephone providers Inmarsat and Iridium agree that Inmarsatโ€™s entry into the market for satellite handsets will quickly reduce average handset prices worldwide.

Inmarsat
expects to carve out a 10 percent share of the global market for hand-held satellite telephones by 2010 following the introduction, late this year, of a sub-$500 Inmarsat handset with global coverage from three Inmarsat 4 satellites.

At that price




Inmarsat will be far less expensive than the competition,




Andy Sukawaty, the companyโ€™s chief executive, said here March 18. โ€œI can guarantee you we will be hitting this market hard,โ€ he said.

But one of London-based Inmarsatโ€™s biggest competitors, Iridium Satellite, plans to drop its prices just as soon as Inmarsat fields a global service, Iridium Chief Executive Matt Desch said.

โ€œWe will be bringing down prices,โ€ Desch said. โ€œWe have charged the rates we have because we can. But this is a high-margin business and we have flexibility.โ€

Bethesda, Md.-based Iridium has been operating on the assumption that competitor Globalstar will be crippled for the next two years because of its satellitesโ€™ degrading voice service. Globalstar expects its second-generation satellite constellation to enter




service sometime in 2010.

With Globalstar less of a factor, Iridium has been able to keep its handset prices high. But the arrival of Inmarsat will change that, Desch said.

Iridium expects to sign a contract in mid-2009 for construction of a second-generation constellation of low-orbiting satellites to be launched starting in 2013. The company estimates it will cost $2.7 billion to build and launch this




system.

Desch
also said Iridium has received higher-than-expected interest from government agencies in placing small Earth observation or other payloads on the Iridium satellites. This secondary-payload opportunity could generate between $800 million and $1.1 billion in revenue




for Iridium over a decade, with some of that




being paid up front to help finance the construction of the next Iridium constellation, Desch said.

Iridium expects to be able to cover




$1.1 billion of the




second-generation systemโ€™s cost




from its own operating cash flow, leaving between $500 million and $800 million to be raised via




outside financing.
