[time-nuts] nuts about position (cheap receiver)

To give an idea about the possible improvement in antenna location available by post-processing the data, I first did a 2 hour self-survey and that put the receiver into position hold mode. Then I collected RINEX data for 16 hours. The post-processed lat/lon/alt values differed around 1/1/3 meters better than the self-survey values (with estimated error ellipses of 0.17/0.15/0.4 meters). Those results were with the "ultra rapid" orbits. It will be interesting to see what they look like when the final precise orbits are available in a couple of weeks.
I also need to see how those values compare to Lady Heather's precision survey results.
