Dear Colleagues,
Due to malfunction of the GPS receiver with the External Frequency
Standard (Cs), I would like to inform you that from DOY 332 (28 Nov. 2001)
12:10 UT, BOR1 (Poland) Station is switched to the Internal Clock.

The data collected between 00:00 UT of DOY 327 and 12:10 of DOY 332 may be
useless (not reliable). Please treat it with caution.

I will send a notification as soon as possible when the problem with
External Frequency Standard will be resolved.

I apologize for the inconvenience.
Best regards
Marek
