Globalstar protested the deal because the Pentagon did not hold a competition for the telecommunications contract, the source said. GAO had placed a hold on the Iridium contract pending its investigation, but the Pentagon was able to have the hold lifted by citing national security reasons, the source said.
The GAO investigation, which began this month, has a 100-day limit, the source said. Pentagon spokeswoman Susan Hansen did not immediately return a request for comment.
