Enclosing class:

TimeOfFlightEstimator

public static class TimeOfFlightEstimator.TofInterval
extends Object

Used for polynomial interpolation of time of flight based on ERT.

Each interval has a start/stop and a set of polynomial coefficients.

The time of flight tof corresponding to a given earth reception time ert is given by the formula:

 delta = ert - ertStart
 tof =c[0] + c[1]*delta + c[2]*delta^2 + ...
 

where ertStart is the start of the interval and c are the polynomial coefficients. delta is the duration of the given ert from the interval start.

delta as well as tof are expressed in seconds.
