The 746th Test Squadron (746 TS), also known as the Central Inertial and GPS Test Facility (CIGTF), has been the DoD's leader in guidance and navigation system testing for over 60 years. While the CIGTF's mission began with inertial guidance and navigation testing, the unit has since expanded its expertise to include GPS due to its success as a navigation aid. Today, the CIGTF is the established leader in inertial, GPS and blended GPS/inertial component and system testing.
The CIGTF's inclusive lab, field and flight-testing capabilities offer the customer a cost-effective means to evaluate their guidance and navigation systems in a variety of environments. Its Navigation Test and Evaluation Laboratory (NavTEL) is a state-of-the-art simulation facility used for testing stand-alone GPS user equipment and integrated GPS navigation systems. Following functional and performance verification in NavTEL the CIGTF can conduct ground and flight tests in diverse locations that include the adjacent White Sands Missile Range (WSMR), the Utah Test and Training Range (UTTR), the Nevada Test and Training Range (NTTR) and the Pacific Missile Range Facility (PMRF) in Hawaii. To accomplish accurate flight and field testing, the CIGTF provides the world's most precise Time Space Position Information (TSPI) Truth Reference Systems. If required, the CIGTF can leverage its Static Antenna Test Range to conduct multi-element GPS antenna testing using multiple jammers in a controlled, open-air environment. This additional cost-effective, repeatable environment can be useful before embarking on operationally realistic NAVWAR field testing.
