Guys,

  The link to the OS site and list on here gives positions of main observing sites in OS co-ordinates. Is there anywhere that you know of where you can acquire GPS co-ordinates.
  I found a site that shows how to convert OS to GPS, but to understand that you'd need to be Carol Vordeman.

  Sorry for these "strange" queries

Is this what you're looking for?
