Hi Poul:

Yes, at day 42 I set the elevation mask to 30 degrees.  I have TAC32 and 
it makes an elevation plot so 30 degrees is well above any of the 
horizon objects.   Today I'm thinking about setting it to 60 degrees 
since only one satellite is needed for timing and this may get rid of 

Have Fun,
