deltaN0Dot - change rate in Δn₀

iDot - inclination rate (rad/s)

omegaDot - rate of right ascension (rad/s)

cuc - amplitude of the cosine harmonic correction term to the argument of latitude

cus - amplitude of the sine harmonic correction term to the argument of latitude

crc - amplitude of the cosine harmonic correction term to the orbit radius

crs - amplitude of the sine harmonic correction term to the orbit radius
