3M 8mm - D8-112 data tape

This unopened 3M 8mm data tape is an example of data tapes used by DSRS - also called an Exabyte tape. DSRS did not use these tapes for their archiving as they were mainly for customer orders where they transcribed selected data onto these and posted them out to the customer. These tapes were used in the 1990s until early 2000s.

Ampex 797 prevision magnetic tape

This is a high density digital tape (HDDT) and is an example of one of the media types once used for archiving data received at the DSRS. This example does not contain any information. These tapes were superseded by a VHS tape based recording system.

Antenna Horizon

A hand-drawn sketch showing elevations of Boiler House, Chimney, Dental Hospital, Tower Building, Medical Building, Tower, Steeple, Belmont Hall, Balgay Hill, Cox's Stack, Law Hill and High Kirk.

AVHRR CCT Format'

Information sheet explaining CCT transcripts of AVHRR raw data from the High Bit Density tape archive can be supplied against specific requests. Recordings are 1600 BPI/PE with parity. Track allocations are described in an accompanying table and goes on to explain how a recording commences, the signal format with a diagram of an AVHRR frarme, the CCT format, and tape length with a diagram of 10 bit words assembled as 8 bit words.

AVHRR magnifications

This overlay was used when a customer required a photographic print. The overlay was used with a quicklook photograph for the appropriate recording to decide which magnification would be suitable to cover the area of interest. Also combined with the prevision overlay is to find the area's approximate position on the archive tape.

AVHRR quicklook weather features

Photographs taken from various Satellites: Clear UK, 14 May 1980-27 April 1999. Clear Europe, 14 May 1979-18 July 1996. Clear Ireland, 1 August 1981 and 17 April 1989. Clear Norway, 10 April 1986-17 March 1999. Clear Iceland, 1 August 1981-13 April 1992. Clear Azores, 3 July 1982-28 February 1992. Clear Alps, 6 March 1989-13 July 1996. Clear Greece, 14 July 1980-17 August 1986. UK and Mist, 9 July 1983-3 April 1999.

AVHRR tapes - format description'

Photocopy of a booklet explaining that due to a recent hardware upgrade at the Satellite Station they are now able to provide an extended range of AVHRR HRPT tape formats and media types. The booklet also includes information on: Supported media types. Supported tape formats. Tape file organisation. Format descriptions. HRPT (CCT/Exabyte) format. HRPT (Cartridge) format. Dundee (CCT/Exabyte) format. Dundee (Cartridge) format. The HRPT signal. The Advanced Very High Resolution Radiometer (AVHRR). The HRPT signal format. AVHRR quicklooks. Choosing a data format.

CCT Format for Dundee University - Photofacsimile Hard Copy Printer'

Information sheet explaining that a photofacsimile machine with CCT interface is available which can hard copy black and white image data from CCTs, provided the tape is formatted correctly. The facsimile machine can print 100, 150 or 300 lines per inch with line totals up to 1000, 1500 or 3000 lines (max. height 10"). Image width is 9.8". The information sheet also explains how to keep the interface and tape format simple, the scaling of data words on the tape, tape formatting along with diagram of a file mark and a tape format.

Computer Tracking System'

Information sheet explaining that this system has been designed to reduce to a minimum of operator intervention in the tracking process, assigning most of the control tasks to a computer which will commnad every movement and supervise every action taken by the operator before and during the tracking. Also explained within the information sheet is the procedure of the tracking system, the controller and status switch, references check, operator intervention during tracking, summary of the starting procedure, running time commands, and instructions if something goes wrong. A set of operating instructions for Computer Tracking System is also attached.

Correspondence

Correspondence with Natural Environment Research Council (NERC), letters of support in resepct of the 2002 NERC review, letters and print out of emails received from the general public requesting copies of satellite images showing the UK covered in snow that was published by the Dundee Satellite Receiving Station (DSRS) during 2010.

Digital Linear Tapes (DLT)

Digital Linear Tapes (DLT) were used as a media type for archiving data received at the DSRS. These examples do not contain any information. Digital Linear Tapes (DLT) are labelled: /1 EOS Tape 5000, 29 April 2000-22 May 2000 /2 EOS Tape 5001, 22 May 2000-5 June 2000 Digital Linear Tapes (DLT) were superseded by Linear Tape-Open (LTO).

Dundee Coastal Zone Scanner (CZCS) CCT Format'

Information sheet explaining that the Nimbus satellite is the principal research and development satellite operated by NASA. The current satellite in the series, Nimbus 7 was launched into a Sunsynchronous orbit at a height of 910km on October 1978. It carried the CZCS scanner which is a multispectral scanner designed for oceanagraphic applications. This scanner records a 1500km wide swath at a spatial resolution of 800m over six wavebands. Also explained within the information sheet is file organistion, signal fornat, CCT fornat, and tape length. The information sheet contains the following tables: Table A-7: the wavelengths for each of the six channels. Table A-8: structure of general data. Table A-9: tape lengths. Table A-12: structure of CCT format . Table A-13: structure of an imagery file. Table A-14: structure of major frame. Table A-15: data in last major frame.
