House Science Committee Hearing on LightSquared Impacts to GPS

On September 8, 2011, the House Committee on Science, Space and Technology held a hearing on the impacts of the LightSquared network on federal science activities. Officials from NOAA, NASA, DOT, USGS, and the National Coordination Office for Space-Based PNT testified that LightSquared interference to GPS could disrupt a broad range of agency operations, especially those requiring high-precision equipment.

The Office of Space Commercialization prepared the testimony delivered by NOAA Deputy Under Secretary for Operations Mary Glackin. She outlined a wide range of GPS-dependent systems and functions at risk, including NOAA’s entire satellite fleet and over 23,000 environmental sensor platforms.
