In cooperation with the University of Padua, Lika Electronic has developed a special model of incremental encoder, mounted on the mechanism of the WAC and NAC telescopes forming the Osiris platform in the Rosetta-ESA mission.
These types of encoders are lighter and have more accuracy; they absorb less power and are able to work within a wide range of temperature. In this mission particularly, they allow the shutter open correctly when taking pictures of the outer space.
Rosetta will orbit around the Churyumov-Gerasimenko comet, inspecting it thoroughly and dropping a Lander onto the comet’s nucleus.
Rosetta will watch dust and vapor gushing from the small nucleus, to form the large head and tail of the comet.
The mission takes its name from the Rosetta stone, which allowed deciphering the script of ancient Egypt.
