Various modifications of the precision solar sensor TDS<\/strong> were installed on the rocket astrophysical observatories K-2 <\/strong>\u2013 K-4<\/strong> and ROS-5<\/strong>, and were also included in the solar stabilization system of the space astrophysical observatory ORION-2<\/strong>. In November 1994, the TDS<\/strong> precision solar sensor was launched into orbit and successfully operated as part of the service equipment of the geostationary meteorological satellite ELECTRO<\/strong> (VNIIEM<\/strong>).<\/span><\/p>\n\n\n\n\n
