In describing the tracking motion of an AZ-EL or ALT-AZ mounted radio telescope, to "plunge" means to exceed 90° in elevation and then to continue tracking as elevation decreases on the other side without swiveling around in azimuth. This is not a capability of DSN antennas.
Industry:Aerospace
A circuitry in telecommunications technology that generates an output signal whose phase is related to the phase of the input "reference" signal. It is an electronic circuit consisting of a variable frequency oscillator and a phase detector that compares the phase of the signal derived from the oscillator to an input signal.
Industry:Aerospace
Electrically conductive fourth state of matter (other than solid, liquid, or gas), consisting of ions and electrons.
Industry:Aerospace
