Abstract

Using a simplified nonlinear approach by Yuen together with simplified series expressions to obtain the nonlinear values for Alpha, Gamma, and Sigma, a full program was developed that outputs estimated two-way jitter in degrees as a function of ground and spacecraft signal-level margin above design point. Required modified (“hyperbolic”) bessel functions were calculated individually, rather than by recursion, with the “defining” series to reduce the error. Results were replaced by linear approximation when the series was no longer feasible, well into the “linear range.” As an experiment, and to establish feasibility of the entire model, programming was done entirely on the table calculator (four card-sides; about 1700 steps).
