Abstract
This paper provides the requirement of green propulsion that will be used on LAPAN-A4 satellite for station keeping. LAPAN-A4 is designed for earth observation mission using high resolution multispectral imager. To maintain the quality of imaging, station keeping is needed especially to keep the orbit sun-synchronous. LAPAN-A4 will be equipped with the propulsion system that uses a green propellant. One of the green propellant is High Performance Green Propulsion (HPGP). HPGP propellant has specific impulse 235 second and LAPAN-4 will apply the nominal thrust of 1 N. LAPAN-A3 orbit data is applied to calculate the local time drifts. For 5 years operation 2.4 kg propellant needed for inclination maneuver every 3 months or less.
