This paper addresses a method for computing eclipse and daylight time for satellites in LEO. Continuous health-monitoring of the satellite is required for the success the mission. For this, the satellites are primarily powered by solar energy but during the eclipse time, the satellite’s functioning is affected as it cannot generate power during this period and also, its temperature drops rapidly. To tackle these issues, computing eclipse time for satellites becomes essential so as to plan for sizing its secondary power source for continuous functioning. In this work, eclipse time is being computed and it is shown that eclipse time is a function of altitude, size of earth and the orbital beta angle.
