Dzhanibekov made five flights: Soyuz 27, Soyuz 39, Soyuz T-6, Soyuz T-12, and Soyuz T-13. In all, I have spent 145 days, 15 hours, and 56 minutes in space over these five missions.
Dzhanibekov got the idea for the design of the Cosmonavigator during a rescue mission to the Salyut-7 space station. The Cosmonavigator is interesting both as a watch / instrument and a piece of history. Not only does it look nice, it has fascinating stories behind it - from the first idea of the design that Dzhanibekov got on the dramatic Salyut-7 rescue mission, to the flights on-board Soyuz TMA-5 and TMA-8, the International Space Station, and finally the Space Shuttle Atlantis, always in the good hands of renowned Russian cosmonauts.
The principle of operation of the device is simple and original. The watch dial has a 24-hour scale divided into 16 sectors, in line with the number of orbits that the station makes per day around the Earth.Based on the map at the Mission Control Center showing the orbit grid, marked all the continents and oceans with different colors and transferred these markings to the dial. If you look at the projection of the trajectory of a spacecraft flying above the Earth, it looks like a sinusoid (a sine wave), and each subsequent revolution is somewhat offset from the previous one. The period of orbit for the spacecraft, that is, the time during which it makes a whole revolution around our planet, is approximately 90 minutes. Based on these data and knowing the initial time, it is possible to calculate over what part of the Earth the spacecraft is located at any given time. The idea of this watch is that, looking at the dial, you could immediately determine where the spaceship is now. To do this, I came up with a special bezel with sectors painted in different colors, representing continents: Europe and Russia - red, Asia - yellow, Africa - black, Oceania - green, North America - dark blue, South America - orange. A spacecraft in low Earth orbit (LEO) makes 16 circuits around the Earth at a 200 km height per day, assuming a circular orbit, with an orbital period of 90 minutes. During this time, the Earth turns, so the start of next circuit begins at new coordinates. The first circuit is defined by the geographic coordinates of the launch site for the spacecraft and mission. The next circuits repeat the first one with a change in the number over the equator 1-2-3 14-15-16 and 1-2-3 again, and so on, forming a beautiful pattern of the spacecraft trajectory on the flat surface of the map.
The Cosmonavigator watch is designed for orbits with planes inclined 51º to the Earth's equator, the working orbits of the Salyut space stations, as well as Mir and the operating International Space Station. They also match the planes of the Soyuz docked spaceships and soon the Falcon 9 missions.
Navigation accuracy depends on the orbital period. If the height increase, the time to complete an orbit will increase too. Therefore, the watch is provided with an option to simply (and regularly) correct the sector position hand relative to the hour hand. This watch was created and designed by and for cosmonauts and its history will forever be part of the annals of space conquest.Russian Space Wrist Watch Spetsnaz (SLAVA) " COSMONAVIGATOR " 9124153-617.
