This project deals with the design of the trajectory of station keeping manoeuvre of a GEO satellite. GEO satellite is a satellite that is at an altitude of about 36000 km. from the surface of the earth and has an inclination of 0o, having an orbital period of 24 hrs. (i.e. it remains constant at a particular longitude). It is necessary to maintain the GEO satellites at their location as they are important for communication, weather forecasting and other operations. Now a days, humans depend on satellites for a lot of operations and thus it is necessary that to maintain these satellites or else most of the day to day activities would be harmed by the loss of any satellite. AGI’s flagship product i.e. Systems Tool Kit (STK) is being used for designing the trajectory for GEO station-keeping of a satellite and then a custom engine is being developed using the API’s available with STK to design an application, which can be used in any system that has STK installed in it. The constraining factor in the design of the trajectory for the GEO station-keeping manoeuvres is that the delta-v budget and the fuel used should be minimum. If these two parameters are minimum then the lifetime of the satellite increases. So, in this application one can notice that both the Delta- v budget and the fuel used too is minimum as compared to the standard values used in the real world scenario. From the application designed it can be conclude that the satellite is well maintained within the GEO box (or its slot) and the Delta-v budget and the fuel used is also minimum.
