Realtime satelite data acquisition with SunOS 4
By pgdh on Sep 03, 2009
Perhaps the most rewarding work I've ever done. The Dundee Satelite Receiving Station had a PDP11 system to capture data from circumpolar satelites, and had recently upgraded to a 4/330 with a DR11W VME board. Unfortunately, this interface had no buffering, and we needed to capture 22K of data at 6Hz. I devised a multiprocess, non-blocking implementation which did the job admirably. My reward was seeing stunning live pictures of the earth. Utterly beautiful!
