Signal strength.

LORAN transmitters put out multi-hundred KW to MegaWatt class pulses. Wiki
has a list. I would think a GPS bird puts out less than 100 Watts CW.
Also, GPS birds are a LOT farther away, especially measured in wavelengths
(much higher path loss)

Those factors combine to make a huge difference in received power. It
could well be over 100 dB.
