NASA has invented a new GPS receiver for implementation in radiation-hardened, space-ready hardware. The receiver has capabilities lacking in all other current commercial space-borne GPS receivers. Namely, PiVoT 2.0 can acquire GPS signals in a fraction of the time taken by these other receivers.
This capability that arises from the use of dedicated signals also leads to the ability to process/track weak GPS signals, which are unusable to most current technology receivers. This weak signal capability opens the door to a host of new applications for GPS.
