The main benefit of JPALS is that it's a system that can be taken anywhere, anytime, providing a safe and effective way to conduct 24/7, all-weather, anti-jam instrument landing system capability to all authorized users, worldwide. A secondary benefit is a significant reduction in cost over current

The development of JPALS was the result of two main military requirements. First, the military needs an all-service, highly mobile all-weather precision approach system, tailorable to a wide range of environments, from shipboard use to rapid installation at makeshift airfields. Second, they need a

LDGPS is further divided into three sub-categories: fixed base, tactical, and special missions. Fixed base is used for ongoing operations at military airfields around the world, while the tactical system is portable, designed for relatively short-term, austere airfield operations. The special
