Hi
If you are doing a longer run into one of the data analysis services - it does not seem to matter much what the
spacing on the readings is. One second data does not seem to produce any better result than 30 second data.
I don’t think that the 3 second rate on the Trimble will have much impact on a 24 hour data set.

A 5 hour 1Hz run was sent to CSRS-PPP and the lat/lon/alt error ellipses were in the 250/250/700 mm range... that should improve with a longer run.
