The United States Space Force’s Space and Missile Systems Center (SMC) announced it has completed the first test of the mitigation and anti-jam enhancement (MAJE) capability for the wideband global SATCOM (WGS) program.

The first article test (FAT) increment 3 took place in June this year and marks the first increment of FAT testing performed for the WGS program under space force.

The space force added that adaptive nulling and detection capabilities were successfully tested during the FAT with the test resulting in passing 165 requirements. The adaptive nulling test demonstrated MAJE’s ability to suppress interference to optimize performance when contested. Detection testing measured MAJE’s ability to detect simulated interferers based on power level and frequency.

MAJE consists of software and hardware upgrades for the Army-operated global SATCOM configuration control element (GSCCE) ground system that performs detection, identification, geolocation and mitigation of unwanted radio frequency energy on the WGS 1-10 satellites.

Upon MAJE fielding to warfighter operations, WGS 1-10 will have an inherent geolocation and interference mitigation capability allowing for quick isolation of unwanted signals and faster restoral times of affected authorized user communications. FAT-4, scheduled for this fall, will test the MAJE system’s Geolocation ability. FAT-5, the final increment of FAT testing, will complete Multi-capability and end to end testing. Successful completion of all FAT increments will establish that the GSCCE-MAJE system is ready to move forward into the interface verification with the Army’s subsystems.

“MAJE will double the anti-jam SATCOM capabilities for six Geographic Combatant Commands,” said Col. John Dukes, SMC’s Geosynchronous Polar Orbit Division senior materiel leader.

WGS satellites are the backbone of the US military’s global satellite communications. WGS provides high-capacity communications for warfighters by providing worldwide, high data rate and long-haul communication for marines, soldiers, sailors, airmen, the White House Communication Agency, the US State Department, international partners and other special users.
