Subject: JPL station update


This is an update of the current status of JPL's receiver installation
for the 15 NASA receivers in the LA network.  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.
