RACK OF ELECTRONIC INSTRUMENTS USED AT ALGONQUIN RADIO OBSERVATORY SITE 3 WITH 46 M. ANTENNA. ARO WAS ESTABLISHED IN LATE 1950S TO PROVIDE NATIONAL RADIO OBSERVATORY PROVIDING FACILITIES TO CONTINUE TO MONITOR SUN IN COLLABORATION WITH DOMINION RADIO ASTROPHYSICAL OBSERVATORY (DRAO) ESTABLISHED IN 1957 IN PENTICTON, BC.

Fonction

RACK OF ELECTRONIC MODULES WHICH WERE PART OF SYSTEM USED TO PROCESS SIGNALS FROM RADIO TELESCOPE. THESE CUSTOM MADE ELECTRONICS WERE USED TO CONVERT OUTPUT OF RADIO TELESCOPE TO VIDEO FORMAT, ALSO ADDING TIMING INFORMATION & OTHER SYNCHRONIZATION DATA TO ASSIST IN ANALYSIS PROCESS.

Technique

COMPONENT OF NRC'S VLBI MK I, WHICH CONNECTED 46 M. DISH AT ARO WITH DRAO IN PENTICTON; IN LATE 1960'S CANADA WAS FIRST COUNTRY TO SUCCESSFULLY DEVELOP RADIO ASTRONOMICAL TECHNIQUE OF VERY LONG BASELINE INTERFEROMETRY, WHERE RADIO TELESCOPES THOUSANDS OF KM APART CAN BE USED TO MAKE OBSERVATIONS THAT WOULD OTHERWISE NEED RADIO TELESCOPE WITH DIAMETER EQUAL TO DISTANCE BETWEEN THEM.
