Time Nutters--

Mark Sims said of the latest release of Lady Heather:

> There are several cosmetic tweaks.  

A major new feature is the ability to write RINEX files for receivers that can output satellite RAW observation data.   RINEX files can be processed to produce very accurate positions (typically 150-250mm for L1 only receivers,  10mm for L1/L2 receivers).   The recommended online processor is CSRS-PPP from Natural Resources of Canada (NARCAN)... they seem to be the only service that supports L1 only data.

In layman's terms, what does this mean with regard to being
able to set an *AFFORDABLE* GPS RX out in the field and use it
to do site surveys and process the recorded RINEX data later to
establish the geo-position of each of the sites within a precision
of +/- a few centimeters?  I presume this may not be a simple as
setting up my Trimble Thunderbolt and Lady Heather V6.0 in the
field and gathering RINEX files for a few minutes....??
