-Now, the boresight you have is not strictly relative to the SBAS solution we are using (since we have not processed IE) so don't expect perfect results (we'd have to compute a new boresight for the SBAS solution to make it clear). It will be good enough to use though. 
  
 Open ScanLook and browse to your project. It will find the *.asc automatically for the INS file and automatically create a *_RawEventsUTM.txt file as the INS Event file. Open ScanLook and browse to your project.

This is because the SBAS orientation is not the same as the IE processed solution. The 180 degree roll will not be perfect but it will be close enough to see how your coverage is.
