A COMBINED LAUNCH VEHICLE AND SATELLITE SYSTEM The present invention relates to a combined launch vehicle and satellite system. More specifically relates to the satellite combined with the launch vehicle's upper stage to provide a more efficient system that includes tank separation technology which allows the satellite system to shed tanks that have used up all the propellants stored therein. The method separation of the tank set is enabled by using a merman band or pneumatic type of separation system; wherein the three bottom tanks (105) are emptied first (202) during the process, followed by the separation of the emptied tanks (203) herein the fuel is completely filled in the second set of tanks (203). The first pair of tanks (103) is then separated after the fuel is emptied (204). Similarly, the plumbing lines (106) are also separated along-with. The separation of the used components is achieved herein (205) and the satellite is ready for orbit insertion (206).
