Date: 29 March 1994

A new site, Chatsworth, has been installed in the Southern California PGGA
by the U.S. Geological Survey.  This is the first site in a planned
densification of the Los Angeles Basin, in response to the Northridge
Earthquake of January, 17 1994.  

The site is operational since March 5, 1994. Data are downloaded
and stored at the SIO archive in the same manner as the other PGGA
stations.  Data from the site are incorporated in the daily PGGA/IGS 
analysis at SIO since GPS Week 741.

The site information form mailed to the IGS is given below.
