Having previously missed a payment to the mobile satellite firm Inmarsat, troubled mobile satellite company LightSquared has now made a payment of $56.25 million in relation to its use of Inmarsat's frequency spectrum.

The two firms have agreed that any payments owed can be delayed until 1 April 2014. The deal allows LightSquared to fight for a reversal of a US Federal Communications Commission (FCC) decision to withdraw permission for it to use ground relays, known as ancilliary terrestrial components (ATCs), which boost mobile satellite communications so they can be received in built-up areas. The FCC moved following allegations that LightSquared signals were interfering with GPS receivers.
