WSS-420 HRPT/CHRPT Weather Satellite System

>>> Prices and availability on request!

The WiNRADiO WSS-420 Weather Satellite System is a complete and fully integrated hardware/software system for capturing and processing data streams from polar orbiting satellites in real time.

The system supports HRPT data streams with 5 multi-spectral channels from NOAA satellites and CHRPT data with 10 channels from the Feng Yun-1D satellite. Data is available immediately after a satellite pass and it can be exported to NOAA Level 1B (HRPT) file format.

The system hardware consists of high-quality components: The dual-axis rotator is a robust unit designed with steel gears for heavy-duty work and extended life, while offering considerable turning and breaking torque. The rotator is driven by a digital control unit, which interfaces with the application software via the computer USB port. The control unit can position the rotator to the desired target position with an accuracy of ±0.5°.

The tripod carrying the rotator and the dish antenna is made from high-quality steel, with telescopic legs independently adjustable for course levelling against inclined mounting surfaces, while the articulated levelling feet allow for fine levelling, even at uneven mounting points. A bull's eye bubble mounted on an upper bracket eases the installation process.

The antenna consists of a 120 cm diameter parabolic steel dish with a tightly integrated prime focussed patch feeder and an attached low-noise downconverter, which translates the 1.7 GHz L-Band frequencies down to 140 MHz.

The receiver is designed to have a compact form factor and fits onto a 2/3 length PCI plug-in card. The front-end employs digital synthesis for frequency control, while data decoding and frame synchronization are done in DSP firmware.

Installation and configuration is made easy by means of a user-friendly software setup wizard which will automatically detect installed and connected hardware. The setup software will also assist with rotator and receiver calibration during initial installation.
