The short life cycles of commercial components create many obsolescence headaches for military electronic-system designers as they try to integrate these high-performance devices into air, ground, sea platforms that must last for decades, that have long system development cycles, and time-consuming testing procedures. As the military looks to leverage more open architectures and commercial off-the-shelf (COTS) technology, the challenge of managing the obsolescence that comes with COTS will only become more difficult.
Backup methods of position, navigation, and timing (PNT) are essential for warfighters operating within GPS-denied environments. Warfighters rely on the U.S. NAVSTAR global positioning system (GPS) and global navigation satellite system (GNSS) for military operations, but are encountering an intense escalation of jamming and spoofing attacks.
