The defence sector makes broad use of GNSS technology, including:
Using GNSS receivers, soldiers and pilots can navigate unfamiliar terrain or conduct night-time operations. Most foot soldiers now carry hand-held GNSS receivers.
Search and rescue:
If a plane crashes and has a search and rescue beacon equipped with a GNSS receiver, it can be located more quickly.
Reconnaissance and map creation:
The military uses GNSS to create maps of uncharted or enemy territory. They can also mark reconnaissance points using GNSS.
Unmanned vehicles are used extensively in military applications, including reconnaissance, logistics, target and decoy, mine detection, search and rescue, research and development and missions in unsecured or contaminated areas. An article (CAMCOPTER® S-100 UAS) about how anti-jamming technology helps unmanned vehicles complete missions in GNSS denied environments is in the 2016 Velocity magazine at: resources.hexagonpositioning.com/camcopter-s-100-uas.
Precision munitions use GNSS to ensure they land on target. An article (GAJT Put to the Test) about the use of anti-jamming technology with guided munitions is in the 2017 Velocity magazine available at: resources.hexagonpositioning.com/GAJT-put-to-the-test.
