JAMFEST

Last November, the 746th Test Squadron (746 TS) planned and executed the latest installment in an innovative GPS jamming exercise at White Sands Missile Range (WSMR), New Mexico. Known as JAMFEST, this program is aimed at providing low cost, realistic, GPS jamming scenarios for testing GPS-based navigation systems, as well as training personnel in unique GPS denied environments.

Last November, the 746th Test Squadron (746 TS) planned and executed the latest installment in an innovative GPS jamming exercise at White Sands Missile Range (WSMR), New Mexico. Known as JAMFEST, this program is aimed at providing low cost, realistic, GPS jamming scenarios for testing GPS-based navigation systems, as well as training personnel in unique GPS denied environments.

Located at Holloman Air Force Base, New Mexico (NM), the 746th Test Squadron, also known as the Central Inertial and GPS Test Facility (CIGTF), is the U.S. Department of Defense (DoD) designated lead test organization chartered to test and evaluate GPS user equipment and integrated GPS-based guidance and navigation systems.

Through partnership with the GPS Wing and the Joint Navigation Warfare Center (JNWC), the 746 TS is able to provide this diverse testing and training opportunity at a significantly reduced cost to JAMFEST participants.

During JAMFEST ’07 — the fifth JAMFEST event since the concept was introduced in 2004 — the 746 TS hosted 17 simultaneous, yet very dissimilar customers, including multi-service DoD agencies, several defense contractors, and other government and civil
organizations.

. . . The overall goal of JAMFEST ’07 was to provide and characterize the GPS jamming environment in multiple configurations to enable the participants to test, train, or gain experience in a GPS-jammed scenario.

. . . One of the primary test resources used to create the jamming environment is the Portable Field Jamming System (PFJS), a modified Ford 350 van with a full suite of GPS electronic warfare (EW) equipment. PFJS elements include TMC Advanced Threat Emulators (TATEs) and TAVIA-32 Emulators (TAVIAs), as well as a variety of high power adjustable amplifiers.

. . . JAMFEST testing began on November 5, 2007, at 1500 MST and spanned the following five days. During the test week, 746 TS engineers conducted GPS jamming operations for 7-8 hours on each test day, and characterized the jamming field with ground and airborne monitoring equipment.

The next JAMFEST is scheduled for mid January, 2009.
