Underwater vehicle navigation using bearing measurements from a mobile beacon
IFAC-PapersOnLineAutonomous underwater vehicles enable efficient underwater operations such as mapping, surveillance, and inspection. However, due to the lack of global navigation satellite systems (GNSS) signals, drift in pose estimates will occur over time. Common solutions to this issue are using either stationary or mobile beacons to provide range and possibly ...

Performance Enhancement of Bearing Navigation to Known Radio Beacons
, 2012 This master thesis investigates the performance of a car navigation system using lateral accelerometers, yaw rate and bearings relative three known radio beacons. Accelerometer, gyroscope and position data has been collected by an IMU combined with a GPS receiver, where the IMU was installed in the approximate motion center of a car.

Analytical expression for uncertainty propagation of aerial cooperative navigation
Aviation, 2021 In this paper, the propagation of uncertainty in a cooperative navigation algorithm (CNA) for a group of flying robots (FRs) is investigated. Each FR is equipped with an inertial measurement unit (IMU) and range-bearing sensors to measure the relative ...

An Iterative Guidance and Navigation Algorithm for Orbit Rendezvous of Cooperating CubeSats
Applied Sciences, 2022 Modern space missions often require satellites to perform guidance, navigation, and control tasks autonomously. Despite their limited resources, small satellites are also involved in this trend, as in-orbit rendezvous and docking maneuvers and formation ...
