Analysis of Orbital Atmospheric Density from QQ-Satellite Precision Orbits Based on GNSS Observations

open access: yesRemote Sensing, 2022
Atmospheric drag provides an indirect approach for evaluating atmospheric mass density, which can be derived from the Precise Orbit Determination (POD) of Low Earth Orbit (LEO) satellites. A method was developed to estimate nongravitational acceleration,
