Re: [guide-user] How Do You Update GRS?

Bill Gray Apr 4, 2014

Hi Pete,

Simplest thing to do would be to download

(about 10 KBytes) to your Guide folder, overwriting an existing copy.
I just updated this to include the most recent Jupos observations, with
an assumed drift of 14 degrees/year.

If you're curious about why the GRS longitude is handled this way,
rather than asking the user to enter a value, the bottom of 'grs_lon.txt'
will tell you more than you ever wanted to know.
