Collaborative Autonomous Vehicles with Signals of Opportunity Aided Inertial Navigation Systems

Distributed Signals of Opportunity Aided Inertial Navigation with Intermittent Communication

A distributed signal of opportunity (SOP)-aided inertial navigation system (INS) framework is presented and studied for vehicles collaborating in an imperfect communication channel. The following scenario is considered. Multiple autonomous vehicles (AVs) are aiding their onboard INSs with global navigation satellite system (GNSS) signals. The AVs draw pseudorange observations from unknown SOPs ...

Low Cost, High Integrity, Aided Inertial Navigation Systems for Autonomous Land Vehicles

Applications of Inertial Navigation Systems in Medical Engineering

Inertial navigation systems are of the most important and practical systems in determining the velocity, position and attitude of the vehicles and different equipment. In these systems, three accelerometers and three gyroscopes are used to measure linear accelerations and angular velocities of vehicles, respectively. By using the output of these sensors and special inertial algorithms in differ...

An Effective Terrain Aided Navigation for Low-Cost Autonomous Underwater Vehicles

Terrain-aided navigation is a potentially powerful solution for obtaining submerged position fixes for autonomous underwater vehicles. The application of terrain-aided navigation with high-accuracy inertial navigation systems has demonstrated meter-level navigation accuracy in sea trials.
