DESIGN OF ARTIFICIAL SUN-SYNCHRONOUS ORBITS WITH MAIN ZONAL HARMONICS AND SOLAR RADIATION PRESSURE USING CONTINUOUS LOW-THRUST CONTROL STRATEGIES

Design of Artificial Sun-Synchronous Orbits with Main Zonal Harmonics and Solar Radiation Pressure Using Continuous Low-Thrust Control Strategies

Artificial sun-synchronous orbits are suitable for remote sensing satellites and useful in giving accurate surface mapping.To design such orbits accurately with arbitrary orbital elements, three control strategies are provided with the consideration of main zonal harmonics up to J4 and solar radiation Disk pressure (SRP).In this paper, the continuo
