 |
|
Hi,
there is an unusual question.
Assume, someone (my friends and me) wishes to establish a new
"amateur" CORS (code and phase, L1-only, post-processing only).
What would we need in terms of hardware, software, and paperware
(though it probably varies)?
Some people are telling me that cesium or rubidium clocks needed for
every CORS, but I think it>s a BS :)
Cheers,
VVX |

"CORS" is an acronym "Continuously Operating Reference Station"
created by the US Geodetic Survey, and it is limited to some very
specific stations in the US and US-occupied countries which were
established under the USGS guidelines.
There are thousands of continuously operating reference stations which
have been established by government agencies and private operators all
over the world. Most of these operators are far more knowledgeable in
geodetic GPS than the Geodetic Survey in the US (a very backwards
country when it comes to surveying and geodesy)
If you are thinking of establishing a GPS reference station for the
use of you and your friends, you can do whatever works for you.
If you want to establish a GPS reference station which will become
part of the US CORS, there are some very specific guidelines as to
equipment, location, survey, connectivity, etc.. |

Sorry, I can>t let some of this go unchallenged.

Firstly, the organization is NGS ( National Geodetic Survey), formerly known
as the US Coast & Geodetic Survey, a completely different organization and
entity from USGS (US Geological Survey). These 2 government entities are
totally separate, although some of what they do may overlap, ever so
slightly.
Secondly, it>s not clear by what is intended by "US-occupied countries",
perhaps it>s a translation problem, but I sense an underlying tone of
derision. Bad phrasing, perhaps?

Surely you jest :-) NGS is the PREMIER organization in the WORLD with
regards to surveying techniques, standards, and geodesy. As a government
entity it performs and returns value better than all others, bar none.
