Analytical expression for uncertainty propagation of aerial cooperative navigation

open access: yesAviation, 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 ...

Navigation by bearing information

open access: closed, 1967
This thesis document was issued under the authority of another institution, not NPS. At the time it was written, a copy was added to the NPS Library collection for reasons not now known. It has been included in the digital archive for its historical value to NPS. Not believed to be a CIVINS (Civilian Institutions) title.

Disturbing impact of multiple wind turbines on the indicated DVOR bearing [PDF]

open access: yesAdvances in Radio Science, 2019
Radio navigation aids, like the Doppler Very High Frequency Omnidirectional Radio Range (DVOR), provide their navigation service by specific radiation of electromagnetic waves depending on the direction in space and according to their specific antenna ...

Range-Only Bearing Estimator for Localization and Mapping [PDF]

open access: yesIEEE Control Systems Letters, vol. 7, 2023, pp. 2503-2508, 2023
Navigation and exploration within unknown environments are typical examples in which simultaneous localization and mapping (SLAM) algorithms are applied. When mobile agents deploy only range sensors without bearing information, the agents must estimate the bearing using the online distance measurement for the localization and mapping purposes.

Applying the Geodetic Adjustment Method for Positioning in Relation to the Swarm Leader of Underwater Vehicles Based on Course, Speed, and Distance Measurements

open access: yesEnergies, 2022
The research consisted of simulating the movement of a single vehicle in relation to the swarm leader on a square-shaped path, taking into account measurement errors characteristic of typical cheap navigation devices and the hydroacoustic system.

An Iterative Guidance and Navigation Algorithm for Orbit Rendezvous of Cooperating CubeSats

open access: yesApplied 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 ...

A Calibration Method of Underwater Transponder Position Based on Maximum Correntropy

open access: yes水下无人系统学报, 2023
The ultra-short baseline(USBL) positioning system is widely used in the integrated navigation and positioning of underwater vehicles. Knowing the precise position of the transponder is a prerequisite for the application of the USBL system for navigation ...

Radio-Frequency Interference Considerations for Utility of the Galileo E6 Signal Based on Long-Term Monitoring by ARFIDAAS

open access: yesNavigation, 2023
The extent to which navigation signals in the E6 band may be impacted by shared spectrum allocations might be underappreciated. This paper presents top-level observations from a multi-year international radio frequency interference (RFI) monitoring ...
