The motion of the Martian satellites

Celestial Mechanics, 1975
An extensive analysis of the motion of Phobos and Deimos from 1877 to 1973 has been fulfilled. The new values of the parameters of the orbital model first developed by Struve have been determined for both satellites. The new sets of the orbital parameters compete with the solutions of similar accuracy found by Wilkins and Sinclair.

A Comparative Analysis and Study on Martian Satellites

International Journal of Engineering Trends and Technology, 2014
The use of satellites in communication systems is very much a fact of everyday life, as is evidenced by the many homes equipped with antennas or dishes used for the reception of satellite television. Satellites offer a number of features not readily available with other means of communication.

Numerical Simulation of the Motion of Martian Satellites

2001
The numerical long-term prediction of the satellite motion is very laborious. This is mainly because the high rate of the change of the right member functions of the classical equation of motion results in a small step in numerical integration and, in turn, in a rapid accumulation of the round-off errors.

Dusty Plasma near the Martian Satellite Deimos

Plasma Physics Reports, 2018
The formation of dusty plasma in the near-surface layer above the illuminated part of the Deimos, the satellite of Mars, due to photoelectric and electrostatic processes is analyzed. Using a physicomathematical model self-consistently describing the densities of photoelectrons and dust grains above the illuminated part of Deimos, the distribution ...

Satellite orbit perturbations in a dusty Martian atmosphere

Acta Astronautica, 2012
Abstract In this paper we calculate the effect of atmospheric dust on the orbital elements of a satellite. Dust storms that originate in the Martian surface may evolve into global storms in the atmosphere that can last for months can affect low orbiter and lander missions.

Models for the Origin of the Current Martian Satellites

2020
The origin of the two small prograde natural satellites of Mars may, or may not, be important in deciphering the early history of planet Mars. There have been many proposals for the origin of Phobos and Deimos but there is no generally accepted model for their origin.

An analysis of Martian satellite photographic observations of 1967

Icarus, 1975
Abstract Photographic observations of the Martian satellites were made at the opposition of 1967 with the Naval Observatory's 61-inch astrometric reflector. A small partially transparent metallic film filter was used to diminish the light from Mars in order that a measurable image for the planetary disk as well as for the satellites could be obtained.

An efficient algorithm for numerical simulation of the motion of the Martian satellite Phobos

Russian Physics Journal, 1994
We give a brief description of an efficient algorithm for numerical simulation of the motion of close planetary satellites. We describe the results of applying this algorithm to the problem of simulating five years of the motion of the Martian satellite Phobos.

Localization of Lunar and Martian rovers without satellite support

2012 19th International Conference on Microwaves, Radar & Wireless Communications, 2012
This paper presents a method for localization of rovers and probes on different celestial bodies. There are no technical possibilities of running a GNSS-like (Global Navigation Satellite System) system on them. The localization is a crucial condition of proper directing the rover to destination of interest and providing relevant scientific data.
