A Synoptic VLBI Technique for Localizing Nonrepeating Fast Radio Bursts with CHIME/FRB

We demonstrate the blind interferometric detection and localization of two fast radio bursts (FRBs) with subarcminute precision on 400 m baseline between Canadian Hydrogen Intensity Mapping Experiment (CHIME) CHIME Pathfinder. In same spirit as Very Long Baseline Interferometry (VLBI), telescopes were synchronized to separate clocks, channelized voltage (herein referred baseband) data saved a disk correlation performed offline. The simultaneous wide field view high sensitivity required for FRB searches implies rate—6.5 terabits per second (Tb/s) 0.8 Tb s?1 Since such rates cannot be continuously saved, we buffer from both locally in memory , write upon receipt low-latency trigger Fast Radio Burst Instrument (CHIME/FRB). deg2 allows us use in-field calibrators synchronize without needing either calibrator observations or an atomic timing standard. addition our observations, analyze bright single pulses pulsars B0329+54 B0355+54 characterize systematic errors.
