Subject: LA Basin Station Update
Date: May 27, 1995
Please note:
USGS permanent sites in the Los Angeles Basin have been upgraded to
low-power Ashtech Z-12 receivers and (Ashtech) Dorne Margolin with
choke ring antennas. Site logs are being prepared and revised.
The basic information for these systems:
CODE Name DOY DHPAB (m)
---- ------------- --- -----
BRAN Brand Basin 139 0.248
CLAR Claremont 139 0.137
HOLC Pearblossom 146 0.085
HOLP Hollydale 139 0.131
LEEP Mt. Lee 139 0.163
LONG Longdon Yard 139 0.148
ROCK Rocketdyne 142 0.142
Please note:
(1) The DOY is the day of year that the antenna was switched. Add one day
to get first full day of data with the new antenna.
(2) There are some discrepancies in the earlier antenna heights. These
will be detailed in the log sheets.
(3) Antenna dimensions and specifications will be circulated later as soon
as they are confirmed.
(4) CHIL (Chilao) is scheduled for upgrade on day 150.
Data are downloaded and stored on the SOPAC GARNER archive.
Data from these sites are incorporated into the daily analysis at SOPAC
which includes IGS, SCIGN (PGGA/DGGA), and BARD stations.
