In January 2001, Global Imaging's Polar Tracker ground station was
installed at UZ-Gidromet (Tashkent) in the framework of the cooperation between the Main Administration of
the Hydrometeorologic Survey of Uzbekistan (GLAVGYDROMET) and the United States Agency for International
The Polar Tracker ground station is a fully integrated satellite tracking, acquisition,
and processing system for the reception of AVHRR-HRPT data of the NOAA polar orbiting meteorological
spacecrafts. The station includes B-2000 Hewlett Packard RISC-based UNIX computers, software for antenna
control and automatic operation, satellite data processing software, and a number of general image processing
and display functions. Polar Tracker data processing software includes functions for AVHRR processing and
TOVS sounder processing.
The Polar Tracker outdoor part includes a tracking antenna, pedestal, D-band feed,
fully sealed low noise amplifier (LNA) and synthesized down converter. Data are sent directly to the hard
disk of the HP workstation via an external multi-satellite bit/frame synchronizer card, which connects to
the SCSI interface of workstation. In the framework of Swiss-Uzbek activities, the receiving station was
integrated into the operational snowmelt runoff forecasting scheme.
