    v3 v4  
    4646    1. The ambiguity fix is shown on the same plot, for a fixed solution this will be 2.
    4747    1. Check the Position Accuracy - this should ideally be less than 0.035m in lat/long and 0.05m in height
     48    1. To change the plot setting select Tools -> Default Plot Settings.
    4849   1. If you do not get an acceptable solution, try to change some of the settings and rerun the processing
    4950    1. Select Windows > Project Overview > Configuration.
    5051    1. On the GNSS tab, select GNSS processing options.
    51    
     52    1. Adjust the settings and try again (e.g. lower the elevation mask, change the ARTK setting)
     53    1. If you want to compare solutions make sure you change the output name (on the Project Overview window)
     54 
     55You can also look at the IPAS solution file (to see the Lat/Long trajectory of the aircraft).
    5256
    53 If you still cannot get a good solution, you can try processing using the old IPAS Pro.
     57To compare two solutions select Compare Solution. You need to first create a difference file, selecting the two *.sol files you wish to use. Then load up the difference file (*.dif).
     58
     59If you still cannot get a good solution, you can try processing using the old IPAS Pro http://arsf-dan.nerc.ac.uk/trac/wiki/Processing/IPASPro

    5763=== Additonal Notes: ===
    5864
    59 The accuracy using IPAS TC is approximately the same as using IPAS Pro and !GraftNav combined
     65The intermediate processing files (e.g. *.fwd, *.rev) are stored in C:\Documents and Settings\$user\Local Settings\Temp\ie - there doesn't seem to be a way to redirect these files elsewhere. They may be needed if we want to be able to import the result into POSPAC?
     66
     67The accuracy using IPAS TC is approximately the same as using IPAS Pro and !GraftNav combined.
    6068IPAS TC can operate with fewer satellites and deeper turns => more reliable observations
