Simplified Method of Calculating Time from Launch to First Track Point for Known Value of g

The derivation of a simplified method of calculating the time from launch to the smoothed estimate of the first track point for a known value of g by least squares fitting a linear equation is presented. This method eliminates the need for the fifth accumulator, normally used for (Equation), as well as the need for processing this accumulated value in calculating the elevation velocity and position of the first data point.
