Effect of Additional Orbit Inclination on Solution for Earth's Gravity Field.

摘要

An approximate method was developed to determine the optimum inclination at which to launch an additional satellite to improve the determination of the earth's gravity field from satellite observations. In an example where data was assumed to be available at orbital inclinations of 65 deg, 90 deg, 108 deg, and 115 deg, the optimum inclination of a new satellite was found to be 95 deg although a nearby equivalent could be obtained at inclinations of 85 deg or below 55 deg.(Author)
