Currently, 6 of the stations are operating, or are being tested, plus 1 additional site (AOA1). Installed are: 1. Mt. Wilson - ID and Lat Lon Ht. : WLSN 34.226112 -118.055906 1696.9778 Type : Solar Telescope Foundation circa 1965 Operating since: 7-15-94 Comments: Possible RFI and Multipath problems. May be moved to another location at Mt Wilson. New site selected; permitting in progress. 2. Pasadena at Caltech - ID and Lat Lon Ht. : CIT1 34.1367 -118.1273 216.8770 Type : Building Operating since: 9-02-94 Comments: No problems. 3. San Fernando Valley at Oat Mtn - ID and Lat Lon Ht. : OATT 34.330102 -118.6014 1016.1 Type : Underground Bunker/Massive concrete structure Operating since: 6-07-94 Comments: RFI and somewhat poor horizon mask. Have obtained permission to move station to a location about 20 meters from the current mark. The new site is characterized by lower RFI, a much better horizon mask, and is likely to be more stable over the long run. The existing monument will be preserved. New monument is being fabbed. 4.
