Prospective SADIS users wanting to access the SADIS 2G Service

Important News:
The SADIS 2G Service will be withdrawn on 31 July 2016.   All current users of SADIS 2G, who do not yet have access to Secure SADIS FTP are strongly encouraged to make preparations to migrate from SADIS 2G to Secure SADIS FTP at the earliest opportunity.  Please contact the SADIS Manager, for further information regarding the reasons behind the withdrawal of SADIS 2G, and how to obtain access to Secure SADIS FTP.

Review the hardware and software procurement guidelines.

Contact the SADIS team to register your intent to access the SADIS 2G service.

Contact your state meteorological authority to seek written authorisation that a SADIS system can be operated by your organisation within your state. The meteorological authority will typically reside at either the Civil Aviation Authority or National Meteorological Service within your state.

It will be at the discretion of your state meteorological authority whether permission is granted to allow access to the SADIS service.

Please send copies of any written authorisation to:

  • Head of UK Met. Authority, Civil Aviation Authority, CAA House, 45-59 Kingsway, London WC2B 6TE, United Kingdom.
  • Your regional ICAO office.
  • SADIS Manager, Met Office, FitzRoy Road, Exeter, EX1 3PB, United Kingdom.

Contact the SADIS 2G hardware suppliers - with a view to obtaining quotations for a full SADIS 2G VSAT (very small aperture terminal).

Users will need to purchase, as a minimum, the following components.

  • A 2G compatible receiver (available from L-Teq, Paradigm and Vados Systems)
  • A Vados Systems VadEDGE router
  • A LNB (low noise block)
  • An antenna (1.8 metre or 2.4 metre are the standard diameter sizes)
  • Appropriate low-loss cable

Note 1: iSat, Paradigm Communications, and Ultra AEP Systems can provide a 'one-box' solution for the 2G receiver and MegaPAC which incorporates the two components inside one physical unit. This unit can be supplied as a hardened case if required.

Note 2: Users located very close to the edge of the SADIS footprint may have to purchase a new low-noise block (LNB) and/or antenna. Discuss this potential requirement with the hardware suppliers. Users located towards the centre of the satellite footprint may be able to use a smaller-sized antenna. Seek guidance from the hardware suppliers prior to making your purchase.

Note 3: Users may wish to consider purchasing a 'turnkey' system (VSAT and workstation) directly from one of the SADIS 2G hardware suppliers.

  • Please inform the Met Office SADIS team when your system has been installed.
