Over its 40 years of operations, notable events 2 Vol 61 June 2019 SpaceFlight BEHIND THE NEWS captured include the Fastnet yacht race storm of 1979, the Buncefield oil depot fire in 2005, volcanic eruptions in Iceland and at Mount Etna, forest fires, severe winter conditions in the UK and Ireland, Atlantic hurricanes and tropical cyclones. The Dundee station archive contains over 200,000 recordings from polar orbit satellites with coverage of Europe and the North Atlantic as well as images from geostationary satellites providing global coverage. Hundreds of scientific papers have been supported with this data as well as many other publications. There is great public interest in the station’s website with around five million images downloaded each year by thousands of users with incredibly varied applications. DSRS currently has five operational tracking satellite dishes for polar satellite reception and a number of fixed position antennas for signals from geostationary satellites. Staff provide the essential electronic hardware and software expertise to design, build, operate and maintain the facility. The high level of in-house expertise ensures an extremely high success rate for collecting data (generally above 99.9% annually) and fast delivery for time-critical applications such as fire monitoring. The DSRS can trace its origins back to the work of Peter Baylis and Dr John Brush in the 1970s when they began picking up data from meteorological satellites. This led to acquisition of a 3.7 m reflector which allowed data to be acquired from the Very High Resolution Radiometer (VHRR) instrument carried by NOAA-4, launched in 1974, and NOAA-5, launched two years later. After the launch of Tiros-N in 1978, the facility began ABOVE DSRS archiving data including that from the satellite’s A rare completely cloud-free view of the British Isles – obtained Advanced VHRR which operated until 1981. from polar satellite data via the DSRS station at Dundee.

Now, DSRS has 388 TB of data storage, essential when considering that the Terra and Aqua satellites alone transmit 1.5 GB and the group also captured data from Nimbus 7, SeaStar and other NOAA satellites as well as Meteosat. Recognition of process occurred when the European Space Agency asked the team to produce a design and construction manual for other users. ADDED VALUE Due to Dundee’s geographic position in the northern hemisphere, the station is well-suited for the reception of “real-time” satellite data covering Europe, the North Atlantic and the Arctic; this is data received from satellites in a polar orbit. DSRS also procured geostationary satellite data such that EOS systems can give full global coverage. The satellite data collected by the DSRS ranged between 250 m to 1 km in resolution. The Station’s operations room has been considerably updated since its inception.
