LightSquared has had a bit of a rough go so far in its attempt to build out a mobile broadband network, which originated over concerns that its spectrum could interfere with GPS systems. The company isn't done trying to gain approval from the Federal Communications Commission for its plans just yet, though. A new filing discovered by the Wall Street Journal has revealed that LightSquared is seeking FCC approval to use its lower 5MHz spectrum that doesn't interfere with GPS signal, as well as another bit of 5MHz spectrum that it would share with the government. A second filing shows that LightSquared would not use the 10MHz spectrum that caused concerns of GPS interference, though LightSquared would like the FCC to reconsider allowing the company to use that spectrum at some point.

Back in May, LightSquared filed for Chapter 11 bankruptcy after failing to gain FCC approval for its network plans and having its spectrum hosting agreement with Sprint killed. The company is planning to ask a judge to extend its time to file a reorganization plan until next summer, which would give it time to gain the A-OK from the FCC on its new plans. Obviously there's still a lot up in the air here, and it's possible that the FCC will still decide not to approve LightSquared's new plans, but the firm is clearly doing all it can to get its network off the ground. We'll keep an eye on the LightSquared situation and give you a shout if anything develops.
