Navigation for fixed-wing unmanned aerial vehicles in the presence of GNSS outages

2013 IEEE International Symposium on Industrial Electronics, 2013
The accuracy of the most commonly used integrated navigation system of inertial navigation system (INS) and global navigation satellite system (GNSS) is greatly influenced by the quality of satellite signals. Based on the most commonly used navigation system that is equipped with barometer and airspeedometer, a new navigation algorithm is proposed for ...

A MEMS-Assisted GNSS Signal Uninterrupted Tracking Method Based on Adaptive Motion Constraints

IEEE Sensors Journal
In cities, global navigation satellite system (GNSS)-based land vehicle navigation is often interrupted due to the occlusion of satellite signals. Even after GNSS signals recover from occlusion, it will take some time for the GNSS receiver to acquire and

An integrated navigation algorithm assisted by CNN-Informer during short-time GNSS outages

Measurement Science and Technology
Abstract Inertial Navigation System (INS) and Global Navigation Satellite System (GNSSs) are commonly used in integrated navigation systems. The GNSS navigation system, however, is not autonomous, and its signals are susceptible to environmental influences leading to poor navigation results.
