Though LightSquared said it has enough funding to keep operating for "several quarters," the company aims to launch its network this year and faces a deadline from its network-building partner, Sprint Nextel, to get FCC approval by the end of this month. On the call, LightSquared said it believed that a new round of more accurate testing could be carried out by the end of February.
The Coalition to Save Our GPS, which represents many GPS vendors and opposes LightSquared's plan, rejected the company's claims and defended the tests.
"The technical evidence speaks for itself and no individual, company or government body can legitimately be blamed for the clear defects of LightSquared's ill-conceived proposal," the group said in a statement Wednesday.
The FCC declined to comment on the validity of the tests.
"We are awaiting completion of recommendations from NTIA. As we have said from the outset, the FCC will not lift the prohibition on LightSquared to begin commercial operations unless harmful interference issues are resolved," FCC spokeswoman Tammy Sun said via email.
