Blind Doppler Tracking and Beacon Detection for Opportunistic Navigation with LEO Satellite Signals
IEEE Aerospace Conference, 2021A 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 ...

Satellite Tracking and ObservationModels
2000Orbit determination of an artificial satellite requires as input measurements that are related to the satellite’s position or velocity. These data are collected by a satellite tracking system that measures the properties of electromagnetic wave propagation between the transmitter and the receiver. The transmitter as well as the receiver may either be a

Spectral representation of the satellite-to-satellite tracking observables
Advances in Space Research, 1991Abstract Using Hill's equations an analytical scheme for the representation of the Satellite-to-Satellite Tracking observables has been developed. As a test, it is applied to a pair of satellites in near-circular orbit, at an altitude around 200 km. The gravitational models GEM-10B and PGS-S4 were chosen to produce a residual gravity field for the ...

Bell System Technical Journal, 1961
This paper is concerned with the radar employed at Bell Telephone Laboratories, Holmdel, New Jersey, site for tracking the Echo I satellite. The radar was originally designed for the sole purpose of antenna pointing. Recently, however, it has also been employed to measure earth-balloon-earth path loss at regular intervals of time in order to keep track

The limits of direct satellite tracking with GPS
26th Aerospace Sciences Meeting, 1988The expected accuracy of the direct user orbit solution and the magnitude of the principal error sources are evaluated using the techniques of covariance analysis. Utilization of advanced GPS receivers, measurement calibration methods, and geophysical models developed for high-precision GPS-based geodesy and differential satellite tracking are assumed ...

Decentralized Telescope Management for Satellite Tracking
2013 IEEE/WIC/ACM International Joint Conferences on Web Intelligence (WI) and Intelligent Agent Technologies (IAT), 2013Currently, over 100 million objects orbit our planet in Low-Earth Orbit (LEO). To track these objects, the United States utilizes the Space Surveillance Network (SSN). However, numerous countries and corporations continue to expand their utilization of space leaving in their wake a sea of space debris.

The satellite acquisition errors for tracking, telemetry and command of the KOMPSAT satellite
ICC '98. 1998 IEEE International Conference on Communications. Conference Record. Affiliated with SUPERCOMM'98 (Cat. No.98CH36220), 2002This paper describes the satellite acquisition error for tracking, telemetry and command of the KOMPSAT satellite. It shows the allowable acquisition errors of the satellite position as functions of angle, satellite path length, and acquisition time. The analysis method at the 3 dB beamwidth is considered as the general one for the acquisition error ...

Satellite-Satellite Tracking for Estimating Geopotential Coefficients
2013Results of simulation studies of tracking of low-altitude satellites by a high-altitude satellite using range measurements between satellites. The high-altitude satellite is tracked by ground-based range trackers. The low-altitude satellites are tracked only by the high-altitude satellites.
