The FIX feature allows the position of a satellite stored in non-volatile memory to be loaded
into the controller's current position counter. This feature is useful if a faulty position sensor or
a noise impulse results in an errant position count.

stored in memory. Use a Ku band satellite if the antenna can receive both C and Ku band.
