[time-nuts] GPS position survey

[Miguel Barbosa Gonçalves]

Hi fellow time nuts!

I've recently bought a Trimble Acutime gold that will be used as a
reference clock for a NTP server.

This receiver has the possibility of averaging it's position before
entering what Trimble calls the overdetermined clock state. The
default is to average the position with 2000 fixes.

What do you believe is a good number of fixes for the survey in this case?

Cheers,
Miguel
