Precise Orbit Determination for Low Earth Orbit Satellites
The precise orbit determination problem is to accurately determine the position and velocity vectors of an orbiting satellite. In this paper we review the general contents of the orbit determination process, with particular emphasis on Low Earth Orbit (LEO) satellites. The different orbit determination approaches and the different force models contained within are briefly discussed. The two mai...
متن کاملCDMA in Low Earth Orbit Satellites
In recent years the use of small multi mission satellites (SMMS) in Low Earth Orbit (LEO) for making voice, data and E-mail communications has been grown extensively. Low production cost, Low cost of lunching and low transmission power due to it’s low orbit of these satellites are some reasons for their vast usage. How over because of their low orbit they need to turn several times around the e...
متن کاملLow-Earth Orbit Determination from Gravity Gradient Measurements
An innovative orbit determination method which makes use of gravity gradients for Low-Earth-Orbiting satellites is proposed. The measurement principle of gravity gradiometry is briefly reviewed and the sources of measurement error are analyzed. An adaptive hybrid least squares batch filter based on linearization of the orbital equation and unscented transformation of the measurement equation is...
متن کاملPhase Error Modeling and Its Impact on Precise Orbit Determination of GRACE Satellites
Limiting factors for the precise orbit determination POD of low-earth orbit LEO satellite using dual-frequency GPS are nowadays mainly encountered with the in-flight phase error modeling. The phase error is modeled as a systematic and a random component each depending on the direction of GPS signal reception. The systematic part and standard deviation of random part in phase error model are, re...
متن کاملEnvisat Precise Orbit Determination
The Navigation Office at ESOC has been closely involved in all aspects of the Precise Orbit Determination (POD) of Envisat throughout the mission lifetime. These activities started shortly after launch through membership of the Orbit Validation Team (OVT). During this time ESOC was involved in both calibration and validation of the DORIS doppler data, the SLR data and the different POD solution...
