TK powers Chinese 425 GHz radiometer in geostationary orbit

TK is proud to have supplied a polarizing grid and an ultragaussian corrugated feed horn for an experimental 425 GHz radiometer now operating in geostationary orbit some 35,786 Km above Indonesia.

The radiometer was designed and built by the Shanghai Spaceflight Institute of TT&C and Telecommunication in Shanghai and launched in December 2016 as part of FY4A, a Chinese optical metrological satellite

The advanced ultragaussian horn provided very low sidelobe feed to the scanning optics: The designed antenna pattern can be seen below
