The satsig calculator returned a value of "NaN" instead of a numerical result. I am trying to point to Telsat Nimiq 1 from Central Florida.

Not a Number perhaps? Don't forget that when you use this site's calculator, that a negative sign (-) must be placed before a number representing west longitude.

You could also try my alternative mini screen calculator at http://www.satsig.net/sf.htm  
I have made it for use on hand held devices and you don't need to input any numbers.  The idea is to select satellite and your location using up/down clicks and then press enter to give the results.
I would be interested to know how you get on with it.  It takes a bit longer to download as it incorporates a satellite database - that needs updating from time to time.
Best regards, Eric.

NaN means elevation too low..
 
This is either because the satellite is below the horizon or if you are performing a link budget that low elevation scintillation effects make the link non-viable.

Nimiq 1 is a canadian sat provider (bell Express V) it's at -92* . From Central florida the elevation is 65 Azimuth 200

I've just tried the http://www.satsig.net/sf.htm calculator.
 
For Tampa Bay (approx 82 deg 30 min west and 27 deg 30 minutes north)  
 
NIMIQ 1 at 91 deg west:-
Azimuth = 201 deg magnetic bearing
Elevation = 56.5 deg
Polarisation = 16 deg clockwise (facing the satellite)
 
NIMIQ 2 at 82 deg west:-
Azimuth = 182 deg magnetic bearing
Elevation = 57 deg
Polarisation = 1 deg anti-clockwise (facing the satellite)
 
I have just amended the location of NIMIQ 2 in the sf.htm database. Sorry for any confusion.
 
Best regards, Eric.
