Filtering module on satellite tracking
AIP Conference Proceedings, 2019The scope of satellite has increasingly attained as one of the most challenging topics due to the attraction of elaborating the outer space. The satellite, as a means of collecting data and communicating, needs a proper calculation so as to maintain the movement and its appearance.

Tracking of a satellite provides the most vital information about its position and its orbit in space. Tracking is very much essential not only during its launch for initial critical maneuvers but even after launch to maintain it in assigned slot in space.

Segmentation-based orbiting satellite tracking
Proceedings of the 5th International Conference on Multimedia and Image Processing, 2020To obtained the trajectory of an orbiting satellite is a fundamental and vital step for space rendezvous and manipulation by space robots. Due to the freely and rapidly motion of on-orbiting satellites, the sudden change in appearance, orbiting satellite tracking is difficult for traditional tracker, which usually relies on a single bounding box of the

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 ...

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.

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 ...

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.
