Radio-Astronomy Centre Control and Data
Processing System
The radio-astronomy centre control and data processing system was the first project
led by Leading Designer 4. The system was intended for the radio-astronomy centre
to be developed in Poland. The basic system requirements were controlling the set
of dishes, receiving remote signals and processing them into a legible form. The
Automation Design Office employing Leading Designer 4 won the contest to design
and implement the system against two leading Polish institutes. Unfortunately, the
First Secretary of the Polish Communist Party cancelled the funding of the radio-
astronomy project in response to mismanagement of an optical astronomy project
which resulted in significant financial losses (Fig.
8.4
).
Due to the embargoes mentioned in Sect.
8.2
, Leading Designer 4 had to use
home-made equipment, which had been obsolete for 5-10 years in the West. He
therefore designed and developed a computer system simulator (Lewoc
1971
) (see
Fig.
8.5
) of the type called several years later an event-driven simulator, in order to
verify that the performance of the systems designed using these components would
meet the system requirements.
