Although airborne platforms exist in many agencies and organizations, their use is commonly restricted to employees and affiliated scientists. In other cases, the complexity, expense, and logistical difficulties of conducting an airborne geophysical campaign may deter scientists from fully utilizing this important geophysical tool.

The geophysical applications discussed in the report require access to GPS signals that make it possible to locate the aircraft's antenna to a few cm. These applications, as well as future advances in airborne technology, are being hampered by the Department of Defense's implementation of Antispoofing, which encrypts the P-code for reasons of national security.
