Copied from the Charter found at the link posted above...
The purpose of this hearing is to examine the concerns and issues associated with interference on the Global Positioning System (GPS) signal from the proposed LightSquared LLC terrestrial broadband network related to Federal scientific activities.
The committee will review the results of recent testing on the impact of the LightSquared network on the GPS signal. Potential interference could disable the GPS signal used for critical U.S. Government services and science missions such as the Next Generation Air Transportation System, Earth and space science missions, communications and navigation, space mission operations, weather predication and climate observation, search and rescue, disaster response and public safety, navigation, geodesy, and marine research platforms and services. In addition, the Committee will examine measures and costs necessary to implement and prioritize mitigation strategies at Federal departments and agencies.
from page 3 of the Charter...
In light of the test results from the TWG and the NPEF reports, LightSquared has proposed a new plan to initiate commercial operations utilizing the lower 10MHz of its L-band spectrum that the company believes will minimize interference with the GPS signal.
While LightSquared maintains its new proposal will significantly reduce interference to a large percentage of the GPS user community, its impact on aviation, space-based, and high precision users, such as the FAA NextGen, NASA Earth Science missions, GPS meteorology, seismology, and NOAA weather satellites and marine surveyors remains uncertain. While these users represent a small percentage of the overall GPS community their services are critical to U.S. government operations and science missions.

It appears the hearing will probably be avialable for viewing later if you cannot watch it live...
