Further methods like the Lambert-Euler method, the p-iteration and the use of f and g series are discussed in Escobal (1965) and Bate et al. (1971). The Ratio of Sector to Triangle As shown by Gauss, the problem of determining an orbit from two position vectors and a time interval is closely related to the problem of finding the ratio of the sector and the triangle formed by the orbit and the radius vectors. Let T a and Tb denote the satellite's geocentric position at times ta and th. The area A of the triangle defined by the vectors T a and Tb (Fig.
Gaussian orbit determination, on the other hand, was originally designed to find the orbital elements from three sets of widely spaced direction measurements. In the case of satellite measurements, it may also be applied to finding the orbit from two position vectors, which is useful if both range and angle measurements are available. The choice of the most suitable preliminary orbit determination method depends strongly on the type and distribution of available measurements, and is still an ongoing discussion, even though most methods for satellite orbit determination were devised in the early days of spaceflight.
Here Re stands for the equatorial Earth radius of 6378 km, while p = a(1— e2) is the orbital parameter or semi-latus rectum. 4°, which is also known as the critical inclination. By choosing this particular value for the orbital inclination of the Molniya satellites, it can easily be assured that the perigee and apogee remain at the desired position even without active correction maneuvers.

Only the part of the orbit which is marked by a bold line, and the corresponding ground track, are visible from the given station ...............
