Satellite Orbit Determination Methods

Preliminary orbit determination using the gauss and the double r iteration methods.

Satellite orbit determination methods.

Observations of explorer 1 and sputnik 2 in 1958 allowed for an accurate determination of earth s flattening. Orbit determination of an artificial satellite requires as input measurements that are related to the satellite s position or velocity. In order to obtain orbital elements of a satellite from angular measurements there are three approaches. In order to improve the autonomy of a maneuvered geo satellite which is a member of a navigation satellite system an integrated design method of autonomous orbit determination and autonomous control was proposed.

The 1960s saw the launch of the doppler satellite transit 1b and the balloon satellites echo 1 echo 2 and pageos the first dedicated geodetic satellite was anna 1b a collaborative effort. Creates a tle from two or three observations of a satellite on a single pass. The advantage is that the accuracy and the precision for determination of satellite orbit are very high and the new method is favorable for various applications. One major application is to allow tracking newly observed asteroids and verify that they have not been previously discovered.

Starting from the basic principles of orbital mechanics it covers elaborate force models as weh. A neural network state observer was designed to estimate the state of the geo satellite with only the intersatellite ranging information as observations. The combination of various signals disseminated and. Models methods and applications.

This fifth version improves convergence characteristics for the three point fit via f and g series. Precise orbit determination pod method rely on techniques similar to those used high precision geodetic receivers such as carrier phase and rtk tailored and optimized for orbit determination. The method is not only for determination of satellite orbit but also for the time transfer with high accuracy and precision. The basic methods were discovered in the 17th century and have been continuously refined.

Useful for initial orbit parameters and for unknown satellite identification. First steps 1957 1970 satellite geodesy began shortly after the launch of sputnik in 1957. Orbit determination is the estimation of orbits of objects such as moons planets and spacecraft.
