What does FPSSE mean or stand for ?

A FPSSE is a component to ascertain and measure the sun’s position relative to an orbiting spacecraft or satellite.Just like 1000 years ago,sailors would learn the maps of stars in the night sky to navigate their ships,Sun sensing instruments are used to determine altitudes,distances and orbital flight paths.

The FPSSE works by allowing a small amount of sunlight to fall up on the instrument. By using trigonometry and calculus,the zenith and other parameters can be measured by a team of flight dynamic engineers back on Earth.
