If you are on the 15th floor of a 30 floor building then you are going 
to have troubles with the GPS in any case. Any view out the window will 
have less than half the sky visible. Sometimes there may not be enough 
satelites visible for a lock.

*Sometimes* my GPS 12XL will establish a lock inside my wooden house 
with asphalt shingles.

Was it the GPS-30PC TAPR bought closout from Garmin? $99, 
http://www.tapr.org/gps/index.html. *Exactly* the GPS you would want for
this task. Bare minimum GPS in a weather tight case with integral
antenna. No display. Only has NEMA serial interface.
