M

The satellite's Mean Anomaly at the chosen time t is determined using the following equation:

M(t) = M_o + 360^o { nDt - INT(nDt) - INT[ [ M_o+360^o( nDt - INT(nDt) ) ] / 360^o ] }

M(t) = 78^o.940629

This equation ensures that the determined Mean Anomaly always lies between 0 and 360 degrees.

To proceed to the next step, the Mean Anomaly must first be expressed in terms of radians by using the following equation:

M(t) (radians) = [ M(t) (degrees) ] [ p / 180^o ]

 M(t) = 1.37777389 radians
