Subject: IRKT: Reference frequency from another H-maser
Dear IGS Colleagues:
Please be informed that after a series of unexpected failures in the
operation of basic hydrogen maser providing activity of GPS and GLONASS
receivers of the Irkutsk IGS/IGEX-98 station, we was forced to change a
reference frequency source. Since of March 23rd, 1999 at 4:00 UT we
connected receivers to another H-maser.
As a sequence, some jumps are possible in the time scales behavior of
all three Irkutsk station receivers participating in IGS (IRKT
-TurboRogue-8000) and IGEX-98 (IRKZ - Z-18, IRKG -Trimble 4000SGL).
Sincerely, Vjacheslav ZALUTSKY
