45 years ago, the navigation and connected system “Parus” was adopted, created by the company “Information satellite systems” named after academician M. F. Reshetnyova “(part of the state corporation” Roskosmos “).
Satellite navigation and connected system “Parus” worked on the basis of spacecraft “Cyclone-B” developing a solven company. The launches of these satellites were carried out since 1974.
The orbital grouping of the Sail system consisted of six spacecraft worked in an orbit with a height of 1000 km. They provided an automated solution to the tasks of navigation and radio communications. In this case, the accuracy of navigation definitions, compared with the previous system “Cyclone”, was increased twice and amounted to 250-300 meters.
Satellite navigation and connected system “Parus” played a significant role in improving the effectiveness of managing the courts of the domestic navy in any area of the World Ocean. The developer team was awarded Lenin and state awards.
