Guided munitions are not as sure as they used to be, given the increasing effectiveness of jammers and spoofing equipment that interfere with global positioning systems.
To counteract the defenses, the military and its industry partners use techniques such as redundant targeting systems like seekers that target GPS jammers, laser-guidance systems or camera-aided navigation, according to a report in Defense News.
Jammers can interfere with weak GPS signals and causes a guided weapon to lose its satellite connection, which could lead to a complete miss or a hit on an undesired target.
"I've got to maintain a lock through the entire operational envelope — that includes get-me-there, that includes the end-game," said Al Simon, navigation systems marketing manager for Rockwell Collins, which has fielded more than 225,000 integrated GPS anti-jam systems.
