One of the mostimportant issuesin theproductivityof thesatellites is the mode timingand the automatic writingof thescenarioon-boardof thesatellite with regard environmental conditions. In order to have the capability to make flight scenariosformissionssent fromgroundstationsormissions that aregenerated automatically, on board timing forecast along with the time to reach thestationor thephoto target will be necessary. on board automatic generation of thescenarioswill reduce the dependency of the satelliteto groundstation. Calculation of the satellite riseandsettimes,without thesatellite passesand orbitdisturbances simulation, would not be possible. This paperpresentsformulaforthesatellite passessimulation, algorithmandtime prediction computation modelingusing keplerianorbitalparametersandreduces the size ofthecalculation utilizing of semimajor axis of the orbit to be usedonthe boardof satellite. Toreduce thevolume ofcalculations,it will be necessary to use numericalmethods forfindingfunction minimums orroots. semimajor axis of the orbitwill decrease the numerical computation to a great extent using the algorithmpresentedinthis paper.
