Its probably a manual base station location problem,
did you add height as well as long lat? did you get east/west sign right
get your base station position by doing an RTK using a local NTRIP 
station if you can and average for 12 hours.
You can also post process with data from a standard reference station.
you can google map it to within a meter or so but you need height too.
Did you wait a good ten minutes to get your fix or float, it can 
sometimes take that long with L1 only to get a good fix.

There is a bug currently under investigation with STRSVR and RTCM3 
conversion whereby doppler is not being recognised by RTKnavi.
This will result in very  poor fix or float sometimes ten times more 
error than using straight raw data.
Do the RTK first using raw data direct , then compare using RTCM3 
If you see a large difference report to the BINR to RTCM3 thread.
