Available in PDF, EPUB and Kindle. Book excerpt: In the orbit determination procedure described in this paper, the set of physical quantities fitted in the computations is not the set of basic measurements made by the ground stations. Rather, it uses the basic measurements on a pass-by-pass basis, together with a preliminary estimate of the orbit, to determine a fictitious position of the tracking station for each pass. It can be shown that the error in station position is also a representation of the error in satellite position at the center time of the pass. Thus, for each pass, a new estimate of satellite position is formed, and a new orbit is chosen to fit these positions. It should be possible to apply this method to any type of tracking data. With Doppler data, the convergence of the orbit determination position is much faster than that of the conventional method. (Author).

Book Synopsis Improvements in Rapid Determination of Geodetic Position by : E. Joyce Greeley
Download or read book Improvements in Rapid Determination of Geodetic Position written by E. Joyce Greeley and published by . This book was released on 1971 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to determine the accuracy achievable in determining the three components of the geodetic position of a site in the minimum time possible, the time required to receive and analyze data from two Doppler satellite passes. If only the satellites now in orbit are considered, this time interval ranges from one to five hours. While it is currently the practice to require a one-week span of satellite observations to determine a precise geodetic position, the study showed that 10 meter accuracy could be obtained in just a few hours.

Book Synopsis Orbit Determination of a Non-transmitting Satellite Using Doppler Tracking Data by : Paul B. Richards
Download or read book Orbit Determination of a Non-transmitting Satellite Using Doppler Tracking Data written by Paul B. Richards and published by . This book was released on 1960 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is presented for predicting the orbit of a passive (non- transmitting) satellite, using exclusively Doppler data collected during one passage of the satellite by a tracking system consisting of only one transmitter and one receiver. Equations are derived which relate passive satellite Doppler tracking data to range, speed and time parameters at closest approach. These determine an ellipsoid whose foci are the transmitter and receiver stations. The satellite lies on this ellipsoid, and its trajectory is tangent to the surface. The satellite position and velocity components at closest approach are calculated on a digital computer using information contained in the Doppler data together with the geometry of the tracking system. Preliminary orbits determined in this way agree favorably with the refined orbits of BRL and Space Track.

Book Synopsis Rapid Determination of Satellite Visibility Periods by :
Download or read book Rapid Determination of Satellite Visibility Periods written by and published by . This book was released on 1992 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a numerical method to rapidly determine the rise- set times of satellite-satellite and satellite ground station visibility periods, with the line-of-sight corrected for an oblate Earth. The algorithm uses space curve modeling technique known as parabolic blending to construct the waveform of the visibility function, psi (t), versus time. The waveform is produced from either uniform or arbitrarily spaced abscissa points, from which rise-set times are obtained by extracting the real roots of a localized cubic polynomial. This algorithm works for all orbital eccentricities and perturbed satellite motion, provided the visibility function, psi(t), does not become discontinuous as it could from thrusting or deploying a tether. For this study, the rise-set truth table is constructed using a standard five second step-by- step integration with a linear interpolator to locate the exact crossing times. ne simulation results from this algorithm are almost identical to those obtained by modeling satellites subject to first order secular perturbations caused by mass anomalies, but generated in considerably less time. Advantages of this numerical method include compact storage and ease of calculation, making it attractive for supporting ground-based and autonomous onboard satellite operations ...

Book Synopsis Determination of Precise Satellite Orbits and Geodetic Parameters using Satellite Laser Ranging by : Krzysztof Sośnica
Download or read book Determination of Precise Satellite Orbits and Geodetic Parameters using Satellite Laser Ranging written by Krzysztof Sośnica and published by Astronomical Institute, University of Bern, Switzerland. This book was released on 2014-04-07 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contribution of Satellite Laser Ranging (SLR) to the definition of the origin of the reference frame (geocenter coordinates), the global scale, and low degree coefficients of the Earth's gravity field is essential due to the remarkable orbit stability of geodetic satellites and the accuracy of laser observations at a level of a few millimeters. Considering these aspects, SLR has an exceptional potential in establishing global networks and deriving geodetic parameters of the supreme quality. SLR faces today the highest requirements of the Global Geodetic Observing System (GGOS) yielding 1 mm of long-term station coordinate and 0.1 mm/y of station velocity stability. The goal of this work is to assess the contribution of the latest models and corrections to the SLR-derived parameters, to enhance the quality and reliability of the SLR-derived products, and to propose a new approach of orbit parameterization for low orbiting geodetic satellites. The impact of orbit perturbations is studied in detail, including perturbing forces of gravitational origin (Earth's gravity field, ocean and atmosphere tides) and perturbing forces of non-gravitational origin (atmospheric drag, the Yarkovsky effect, albedo and Earth's infrared radiation pressure). A multi-satellite combined solution is obtained using SLR observations to LAGEOS-1, LAGEOS-2, Starlette, Stella, and AJISAI. The quality of the SLR-derived parameters from the combined solution is compared with external solutions. The Earth rotation parameters are compared to the IERS-08-C04 series and the GNSS-derived series, whereas the time variable Earth's gravity field coefficients are compared to the CHAMP and GRACE-derived results.

Book Synopsis Satellite Orbit Determination Using Payload-Collected Observation Data by : Nicholas Bijnens
Download or read book Satellite Orbit Determination Using Payload-Collected Observation Data written by Nicholas Bijnens and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The algorithm developed in this research provides a novel way of preparing the space industry for the future. The rapid rise in small satellite deployment and miniaturization of communication technology will require a cheaper, leaner and more efficient way of tracking those satellites. Using the already-collected timing data from the payload observations means that no additional on-board equipment or processing will be required and that it could even be applied to existing missions, as well. This thesis provides a solid foundation and development analysis to support this new way of using satellite payload data. It shows how combining even the most basic form of observed data (the time-of-access and location) can provide deeper and more insightful knowledge. Each cost function used and explored combines this data in a different manner and, therefore, provides a different kind of insight pertaining to a different aspect of the satellite behaviour. This, combined with the power of machine learning, has proven to be an effective way of determining the position and velocity of the satellite with strong potential for future development in real-world Earth-observation or, perhaps even, interplanetary missions.
