Orbits about the sun intended for radiosonde observations of the solar space
Abstract
The problem of obtaining an orbit about the sun whose orbital elements coincide with the elements of the earth's orbit is examined. The perihelion argument of the former differs from that of the latter by 180 degrees. If the probe is placed into a heliocentric orbit that is symmetrical to the earth, then the earth, sun and probe will be always situated on a straight line. This is termed the antiterrestrial orbit. Two schemes of achieving such an orbit with the aid of two intermediate orbits are proposed. It is assumed that all maneuvers are executed instantaneously, that both the earth and the probe move only in the gravitational field of the sun, and that the earth's sphere of influence is negligible compared with the distance between the earth and the sun.
