Code 53, Display Last Pass (2D)
Enter code 53 to display the last satellite pass and two dimensional position. The
two dimensional position computation is based only on data from the last pass. The
data is displayed in a sequence of seven displays. Press the enter (E) key to erase
one display and view the next. The initial display shows the following information:

Number of iterations in the 2D computation.
Number of 23/28-second doppler counts used in the computation.

Press the enter (E) key. Display shows the geometry of the pass and the standard
deviation of the doppler count residuals in meters. The geometry gives the
direction of satellite travel at closest approach (N = north, S - south) followed by
the position of the satellite at closest approach (E = east, W - west) with respect
t o t h e s i t e .
