Subject: Continued problems with PETR

PS TRACKER ID: PETR
DOMES No.:      12355M001
LOCATION:       Petropavlovsk-Kamchatka, Kamchatka Peninsula, Russia
                NEDA: Northern Eurasia Deformation Array created and run by
                RUSEG: Russia/US Experiment on Geodynamics by GPS Technology. 
                NEDA operational control is provided by RDAAC: 
                Regional GPS Data Acquistion/Analysis Center, Moscow, Russia 
                (contact Grigory Steblov: [email-masked])

We recommend TO DISREGARD ANY DATA collected at PETR since 27-JUL-98 (DOY 208)
until further notice.

REASON: Continued problem with locking enough satellites at local (Kamchatka)
        daily hours (See our IGSMail of: 
        Mon Jul 27 9:01:03 PDT 1998 / Message Number 1964).

The antenna has been replaced but no improvement.
Intense radio noise is suspected.
An experiment with the older (Ashtech Geodetic L1/L2 P) antenna will be
performed today.
