Introduction

Background

One of the most essential satellite communication systems is the Military satellite communication; it has become essential over the passage of time because the war fighter see the enemies through the satellite system. Also, known as the fog of war this system provides the United States of America's military with guaranteed connectivity all across the global. It is accessible even in the remote areas where there is no such proper infrastructure of communication.United States of American military communications satellite system

DSCS III spacecraft uses reaction wheels that are 3-axis alleviate using reaction wheels which are 0.1 deg manage in pitch revolves around the earth as well as the sensors of the sun. In the year 1977 in mid February General Electric obtained a contract for Defense Satellite Communications System III. The initial launch of the satellite was in the year 1982. Similarly the recurring cost associated with the system was stated as 160 million US Dollars.DiscussionArchitecture of Defense Satellite Communications System

The architecture of the Defense Satellite Communications System maneuvers in the SHF rate of recurrence and it also comprise of the orbit, earth, and power sub divisions. The constellation of the DSCS III is made up of (6) six satellites that are present in the geo-stationary orbit. All the satellites in the orbit are three-axis stabilized vehicle that are still using the unchanged SHF band which was used in Defense Satellite Communications System II. The system works under one channel per transponder, which means that the six channels have six transponders.Capability of DSCS III Satellite

The Defense Satellite Communications System III satellites supply considerable potential to sustain driven relations between all workstations as well as to authorize AJ communications along with controlling the satellites throughout disaster and unforeseen situations. Defense Satellite Communications System III satellites works in the region of X-band supplying uplink services up to 7900 to 8400 Mega Hertz band along with the provision of down link services that are up to 7250-7750 Mega Hertz band.

Payload Configuration

All the channels are assigned to its individual limiter; the mixer along with transmitter is modified so as to prop up explicit category of client requisites. In Defense Satellite Communications System III the performance of the Communication is improved via assigning the autonomous channels as per the equipped needs.General Characteristics of Defense Satellite Communications System III

Name of the system: DSCS III, which stands for Defense Satellite Communications System III. Design Life of the satellite: 10 years. Launch Weight of the satellite: 1980 pounds. On-orbit Weight of the satellite: 2550 pounds. Size of the satellite: 80 inches height, width of 75 inches and depth of 76 inches. Solar array span of the satellite: 38.1 feet. Structure of the Satellite: mega light-weight element pulverized aluminum along with magnesium composition by means of more than 80 complex fused components.Conclusion

The Defense Satellite Communications System III is one of the most improvised versions of all the satellites that have been launched up till now.
