AMU is Amplitude Measurement Unit; I think it's specific to
Trimble. I don't know the context or the conversion between
AMU and other units like dB/vHz or SNR or C/N.
Google for words like AMU Amplitude Measurement GPS SNR
and you'll get the idea. A couple references give formulas or
conversion tables. For example, see near page A-68 in one
of the Acutime2000.PDF files.
