In this article, the form and flow of information from signal reception to recorded bits at each station, through cross-correlation, phase-tracking, phase calibration, and bandwidth synthesis, to final observable formation are traced.Abstract:
The form and flow of information from signal reception to recorded bits at each station, through cross-correlation, phase-tracking, phase calibration, and bandwidth synthesis, to final observable formation are traced. In this process the data volume is greatly compressed for each observation, from approx. 10 to the 9th power bits on the station tapes to only four final observables: amplitude, delay, phase-delay rate and RF phase. After phase calibration and propagation media calibrations, the final delay observable is shown to be the sum of a geometric delay and a clock synchronization offset.read more

TL;DR: In this paper, a series of experiments, primarily with NASA's Deep Space Network (DSN) antennas, has been conducted to develop two generations of very long baseline interferometric (VLBI) systems.
Short baseline phase delay interferometry
TL;DR: In this paper, differentially phase delay observations of close quasar pairs on both a 5.9-km and a 253-km baseline (DSS 13-Owens Valley Radio Observatory) have been performed to study the potential navigational precision and accuracy of the short baseline interferometry.
The JPL Extragalactic Radio Reference Frame: Astrometric Results of 1978-96 Deep Space Network VLBI
TL;DR: The JPL 1997-3 celestial reference frame is derived from very long baseline interferometric (VLBI) measurements of 291 compact extragalactic radio sources as mentioned in this paper, and it provides an important independent verification of the International Astronomical Union (IAU) new International Celestial Reference Frame at the level of a few hundred μas.
Phase Calibration Tone Processing With the Block II VLBI Correlator
TL;DR: It is concluded that the tone amplitude variance is a function of one parameter|the number of bits correlated|to within§10, which is due to oversampling, flnite side-band rejection, clipper bias, and phase model quantization.
