•Overnight calibrator observations used to update locations and
motions of selected
communications satellites
•
•Overnight calibrations used as starting point for full-disk
mapping and establishment
of positions of dominant solar compact sources
•
•Solar self-calibration used to refine antenna phases
–Will gradually increase uncertainty in location of solar
sources.
–
•Periodically, a small subset of antennas briefly observe a
pre-located communications
satellite. (Preserves continuity of
solar coverage.)
•
•Returning subset is used to update absolute locations of
compact solar sources.
•
•At end of day, long calibration on phase calibrator to confirm
inferred antenna phases and
compact source locations.
