Time-of-Arrival Estimation for Integrated Satellite Navigation and Communication Signals

IEEE Transactions on Wireless Communications, 2023
Global navigation satellite systems (GNSSs) are used in numerous fields, but their vulnerability is a global problem that has yet to be solved. A promising way to effectively address this problem is by integrating navigation into emerging dense ...

Simultaneous LEO Satellite Tracking and Differential LEO-Aided IMU Navigation

2023 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2023
A navigation framework with differential measurements from low Earth orbit (LEO) satellite signals of opportunity is presented. This framework comprises a navigating rover with unknown states and one or more base stations with known position(s).

The Navigation of Navigation Satellites

Journal of Navigation, 1986
The orbits of navigation satellites have to be determined very precisely. The Transit broadcast (predicted) ephemeris, which is computed by the US Navy Astronautics Group, has an estimated orbital positional accuracy of the order of 25 m in each direction.

Satellite Based Navigation [PDF]

open access: possibleAircraft Engineering and Aerospace Technology, 1985
INTENDED to provide highly accurate three‐dimensional position and velocity and precise time on a continual global basis, the NAVSTAR Global Positioning System (GPS) has been under development by the US Department of Defence since the early 1970's. It is a satellite based radio navigation system which, when it comes into operation in 1988, will consist

Satellite navigation

XRDS: Crossroads, The ACM Magazine for Students, 2014
Chapter 2 defines the specific term of Satellite Navigation and introduces its basic concepts in this chapter. It starts by formally defining and explaining the service aspects of Satellite Navigation, and in this context, it defines the service parameters to be warranted while offering the satellite navigation services.

Blind Doppler Tracking and Beacon Detection for Opportunistic Navigation with LEO Satellite Signals

IEEE Aerospace Conference, 2021
A Doppler tracking and beacon detection framework for blind opportunistic navigation (BON) with low Earth orbit (LEO) satellite signals is proposed. The BON framework cognitively deciphers partially known signals of opportunity (SOPs) and exploits them ...

Assessing Machine Learning for LEO Satellite Orbit Determination in Simultaneous Tracking and Navigation

IEEE Aerospace Conference, 2021
Machine learning for orbit determination of low Earth orbit (LEO) satellites in a simultaneous tracking and navigation (STAN) framework is assessed. STAN is a navigation paradigm that aims to exploit LEO satellites, which are not intended for navigation ...

On-Orbit Calibration Method for Redundant IMU Based on Satellite Navigation & Star Sensor Information Fusion

IEEE Sensors Journal, 2020
Aiming at the long term and high-precision performance maintenance requirements of the satellite-borne four-axis redundant inertial measurement unit (IMU) in space, the satellite navigation velocity information, the attitude information provided by the ...

Satellite Navigation and Sources of Errors in Positioning: A Review

2020 International Conference on Advances in Computing, Communication & Materials (ICACCM), 2020
The demand for satellite navigation is increasing exponentially. Even a handheld device (cell phones) can perform positional services due to the advancement of technology. However, the knowledge of its structure and working detail still requires a lot of

Navigation for Satellites

2016
Navigation is a main challenge for the operation of an autonomous satellite. This paper deals with the problem of pose estimation for real-time vision based navigation system. Presented method is able to estimate the target pose with high accuracy and does not require any landmark on the object. The results of numerical simulation were presented.
