Yes, that is true.
However, what you want to consider is that a window in an office
has metalized glass. This is done to keep out (and in) the heat, and
allow the light
to pass. This can best be recognized when opening a window. The glass
considerably darker than the open window (brownish, greenish).
Such a window will not pass radio signals very well, and the GPS
be very poor when the antenna is mounted behind it.
So, at least mount the antenna outside. When you use the typical
meant to be stuck to a car roof, you can stick it to a strip of metal
that you attach to
the window frame, which holds the antenna out maybe 30cm (1 foot).
Of course a location with all-around coverage is always best, but for
it matters less than for positioning.
