The JGM3 model of Earth's gravity is expressed in the form of coefficients C and S to Legendre polynomials in r, theta and phi which give the gravitational potential
U = [tex]\sum[/tex][tex]\sum[/tex] CV + SW
Can anyone tell me the algorithm for calculating acceleration vector g(r, theta, phi) from the coefficients, i.e. [tex]\Delta[/tex].U expressed as a polar vector?
Thanks
Robert
