phase data (u-blox receivers will do this) and ideally a well-characterised
external antenna (these are quite expensive).
That's very useful. Thanks. I am indeed using a uBlox device as my base
station. I ran it for 48 hours and got accuracy to maybe half a metre, but
I haven't tried post-processing thedata.
However, that still leaves the fundamental problem: I can (and will)
publish the kit of parts for making your own base station. You could use
something similar to build a rover or you could buy one off the shelf.
According to the ads this will give you an accuracy of 2 cm, but how will
you check that you really are getting that accuracy?
That question was the driver for my original posting.
