GPS TRACKER ID:	DAV1
DOMES No.:      	66010M001
CDP No.        		n/a
MONUMENT No.   	AUS99
LOCATION:      		DAVIS Base
				Australian Antarctic Territory
				ANTARCTICA

ADVISORY:

Problems with the data from DAV1 has forced us to discontinue with the sites
operation until the problem is rectified.
It is not certain but the problem may be caused through high oionospheric
activity at this location.
An upgraded AOA  ACT receiver has been rushed down to the base on the last
voyage for this season with the hope that this will solve the problem.
Data from this site started to deteriorate from around doy 300 (1999) and
should be used with caution from there on.
Data from this site has ceased from end of doy 047.

I opologise for the disruption to this service.

Regards
Bob
