Thanks, Magnus. I've not heard of ICD-GPS-2000 or ION red book before.
Perhaps one day I will look them up.
GPS continues to impress me - I counted and on holiday recently we took
(at least) 7 GPS receivers - his and hers smart-phones, 2 iPads, Garmin
GPS 60 CSx, Ventus 750, and one built into my Sony HX200V camera! The
Garmin spent much of its time with a puck antenna stuck on the cabin
porthole plotting our course.
