Frustrated by the occasional time to FIX I had a little poke around looking at low cost L1/L2 GPS units.
Came across RTKLIBexplorers recent post
It was full of really useful snippets like:
Galileo (Exx) and SBAS (Ixx) satellites have less cycle slips than any of the other satellites.
The results for the L1/L2 receiver he used were less than remarkable (dare I say poor), I was surprised. So I will keep Reaching for the perfect post processing configuration that will deliver perfect results.
