Magnus,
How do they compare in price to the receivers we normally use for timing?
Do you see any advantage for a timing receiver to fix faster than once per second?

I have receivers which can run navigation solutions up to 10 times per
second and raw-data results up to 50 times per second, I just don't have
that neat options in it. Ah well. Double-frequency never the less.
