Ladies and Gentlemen,

We have replaced the ASHTECH Z-XII3 receiver
S/N LP03169 Firmware 1K00-1D04 with the
ASHTECH Z-XII3 receiver S/N LP00846 Firmware
CD00-1D02 (Z-12 CGRS) in the WTZA GPS
Permanent Tracking System (which is operationg in
addition to WTZR, WTZT and WTZZ), 04-SEP-2001,
11:30 UT.

The ASHTECH Z-XII3 used the internal oscillator
prior 04-SEP-2001.

After 04-SEP-2001 also the ASHTECH Z-XII3 use the
external oscillator frequency from the H-Masers here in
Wettzell, like the AOA SNR-8000 ACT (WTZR).

With best regards
Rudi
