Well let’s concentrate on your “in the field” problem and look at other things when you get home. By all means update SGP. This will install Platesolve2, but you then also need to download an index catalogue. See this thread for instructions (just download the APM catalogue):
Hopefully with platesolve 2 you will be able to solve successfully in the field, and then we can look at your blind solve failover (astrometry/ansvr) when you get home.
