Phil,
The Federal Geodetic Control Committee (now Subcommittee) has a set of
standards still in draft form but available from the NGS information 
center at 301.713.3242.  The document is "Geometric  Geodetic Accuracy
Standards and Specifications for Using GPS Relative Positioning 
Techniques," version 5.0 dated 11 May 1988 reprinted with corrections 
1 August 1989.
This document is still being used to evaluate proposals for survey
projects submitted to the NGS.  The document is a quite useful aid
to the design of projects as it includes guidelines for field survey 
and office procedures.

Ron,
I recall an artical in either POB or Professional Surveyor about 1 year
ago citing exactly this case.  If you need a specific issue or a copy of
the article, let me know.  Furthermore, you may want to contact Knud
Hermansen in Maine.  He is very knowledgable of the case law.  You can
find his e-mail address at the Land Surveyors Reference Page.

Phil,
Today I attended a BOD meeting for a state surveying society where our
ACSM liason announced that ACSM has launched a committee specifically
for making a recomendation on GPS standards.  For further info. on the
subject you may want to refer to NGS standards for "bluebooking" a
point, etc.

I am a surveyor in Columbus Ohio.  I have my own consulting buisiness,
and also am the chief Surveyor for a corporation that is in the
cellular buisiness. We run 3 crews and I am looking to buy a GPS
system to locate LAT/LONG for FAA data needed for applications for
cellular tower sites, also to obtain a true azimuth (and quite wasting
time with hasty solar observations). The system I am looking at is the
Topcon turbo g-2 hand held reciver using an external antenna,, and 2
units I would like to get +/- 25', Topcon has told me that using a
Coast Gaurd becon (if available) I would get better results, and the
post-process program I can achieve my goal.  The cost I belive will be
around $11,000 with 2 recievers, external attenas, radio reciever, 2
tripods, postprocess software, and a new laptop.  Does anyone know of
a similar system that I can get for the same $$Money or less,and  that
will get the results.  Or is any of this info seem un-realistic, I
have been told by another, that is very active in geodetic GPS work
that I can not overcome the 300'(government Scramble) unless I occupy
a know USGS or GPS coordinate, although Topcon says that they stand
behind there promise. this week I an going on a test with a salesman,
we will compare the info from the GPS to a known baseline.
Any replys are welcome:
