Dear Colleagues,

	We have recently (11/07/03, DOY 192) upgraded the firmware on
our AshTech Z12T GPS Receiver from version 1L08 to 1L01. Please note
that the header files will denote this change. The change has meant that
the automated process of downloading the data to a PC fails, and so we
are doing this manually. The new version of the firmware seems to be
giving corrupted data, so please ignore NPLD data from DOY192 onwards.
We are currently looking into solving this problem, and will notify you
when our data is valid again.

		Thanks,

			Peter Stacey
