LightSquared’s planned nationwide 4G broadband network got yet another reprieve from Sprint today.

LightSquared is coming under pressure from several separate directions, as opponents to its plans provide more specific support to their positions on legal, financial and technical issues. And in the background, a telecom industry heavyweight with whom LightSquared hopes to form an alliance wants clarity by year-end.

NBAA helped to pioneer the transition to GPS-based flight decks and procedures, and now the group is taking a leading role to voice the U.S. civil aviation community’s concern about LightSquared’s threat to GPS.

Clearly impatient with the way the company’s plan for its nationwide broadband Internet project is becoming further and further delayed by opposition from the GPS user community, several federal government departments, members of Congress and, reportedly, within the FCC bureaucracy itself, a LightSquared
