Northrop Grumman Corp. demonstrated a GPS range-tracking system developed for the Minuteman-3 intercontinental ballistic missile (ICBM), the company announced Feb. 9.

The system, one of two independent tracking systems required for range safety, was developed, tested and provided as part of Northrop Grumman Mission Systems’ role as the U.S. Air Force’s ICBM prime integrating contractor.

The Minuteman-3 incorporates GPS translators on the missile to receive information from the satellites and relay translated time and identification data to ground facilities, allowing for more accurate calculation of position and velocity of the missile during flight.
