Alternative Sensors and Emerging Navigation Technologies
Sensors complementary to GNSS and inertial navigation systems and considered new technologies under development for navigation in GNSS-denied environments. Radio frequency technologies such as terrestrial and signals of opportunity (SOOP) including the use of cellular, Wi-Fi, ASTC, DVB-T, DAB/ DMB and AM/FM transmissions for positioning and navigation.
