- Introduction
Problem statement. Observations of the satellite were made, distances to its three instantaneous positions and topocentric directions from the point of the earth's surface were determined. It is necessary to calculate the elements of the satellite's orbit and develop a computer model in the MATLAB application packages.
- Method of research
2.1. Execution of the work
I step. Calculation of satellite orbit elements. To do this, we use a modification of the classical Gauss method.
