Receiving uplinked radio alerts from earth satellite tv for pc transmission stations (antennas). The attitude and orbit control subsystem consists of sensors to measure vehicle orientation, management laws embedded in the flight software program, and actuators (reaction wheels, thrusters). These apply the torques and forces needed to re-orient the automobile to a desired attitude, hold the satellite in the appropriate orbital position, and maintain antennas pointed in the right directions. Nuclear power sources (Radioisotope thermoelectric generator) have additionally been used in a number of profitable satellite programs including the Nimbus program (1964–1978). The satellite’s practical versatility is embedded within its technical elements and its operations traits.

The commonly used altitude classifications of geocentric orbit are Low Earth orbit (LEO), Medium Earth orbit (MEO) and High Earth orbit (HEO). Medium Earth orbit is any orbit between 2,000 and 35,786 km. High Earth orbit is any orbit larger than 35,786 km. Tether satellites are satellites which are connected to another satellite tv for pc by a skinny cable referred to as a tether. Space stations are artificial orbital structures that are designed for human beings to live on in outer house.
