Optimal Control of Low Propulsion Orbital Transfer Time [PDF]

فصلنامه علوم و فناوری فضایی, 2011
Within operational life of satellites according to their mission, need to change their operational orbits. This change can includes change in semi-major axis, inclination or plane of orbit (RAAN angle). For this propose, we can use Electrical Propulsion (

High-Precision Time Transfer and Relative Orbital Determination Among LEO Satellites in Real Time

Navigation
For low-Earth-orbit (LEO) satellites, high-precision clock estimation often depends on high-precision real-time global navigation satellite system (GNSS) products. Thus, service providers often choose to downlink observation data to the ground to achieve
