The Tashkent
Astronomical Observatory (Ulugh Beg Astronomical Institute of the
Uzbek Academy of Sciences since 1966) was involved to the International
Latitude Service (ILS) in Sept.1899, when the regular latitude measurements
were started at Tschardjui (j = +39°08¢11², l= -63°29¢). Because of
the Civil War in Central Asian area, the latitude observations were
ended at Tschardjui in May, 1919. A new latitude station was established
at Kitab (Uzbekistan) on the latitude j = +39°08¢40² and the longitude
l = -66°53¢, in Nov.1930. The Kitab Latitude Station was equipped
with two visual zenith telescopes (1929, 1957) and the photographic
zenith tube removed from the Pulkovo observatory in 1978. The Kitab
station provided the ILS with more than 250000 instantaneous latitude
measurements. Since the early 90s Kitab hosted the ground based beacons
of GPS, PRARE and DORIS satellite tracking systems, providing IERS
data center with precise coordinates at subdaily frequency. In 1998
Kitab Latitude Station was renamed on Department of geodinamics of
Astronomical Institute of the Uzbek Academy of Sciences.
