Electric propulsion systems for satellites

Roundup

Electric propulsion (EP) is an in-orbit technology that can add a new dimension to the way that satellites operate in space. Unlike traditional chemical propulsion systems, which rely on the combustion of fuel to generate thrust, electric propulsion uses electrically charged particles, resulting in an efficient and precise form of propulsion.

Electric propulsion-based thrusters have a variety of potential advantages over traditional chemical propulsion, including greater fuel efficiency, longer mission lifetimes, and greater maneuverability.

One of the most common types of EP used in satellites is ion thrusters. These thrusters work by ionizing a gas, typically xenon, and accelerating the resulting charged particles out of a nozzle to create thrust.

Ion thrusters’ ensure efficiency due to high exhaust velocity, which is typically significantly higher than that of traditional chemical thrusters. This enables spacecraft to achieve greater speeds and travel further distances, making it a very suitable option for long-duration missions.

Another form of electric propulsion is Hall thrusters. These work similarly to ion thrusters but use a magnetic field to accelerate the charged particles instead of an electric field. Hall thrusters are known for their high thrust efficiency and ability to operate at a higher power level than ion thrusters. They are often used in applications that require high-thrust, such as orbit raising and station-keeping.

Electric propulsion systems can usually operate for extended periods without the need for refueling, allowing for longer mission lifetimes. In addition, EP systems are highly controllable, allowing for precise adjustments to satellite trajectories and orientation. This precise control is particularly useful for maintaining a satellite’s position and avoiding collisions with other objects in space – an increasingly important application as the volume of space traffic grows.

Despite the many advantages of EP, there are some drawbacks to consider. Electric propulsion systems typically have lower maximum thrust levels than traditional chemical thrusters, which can make them less suitable for certain applications such as initial orbit insertion. Electric propulsion systems also require a significant amount of power, which can be challenging to provide on smaller spacecraft.

Overall, EP thrusters provide an efficient and precise form of propulsion that is becoming increasingly popular in the satellite industry. As technology advances, it is likely that we will see even more advanced electric propulsion systems developed, allowing for even greater efficiency and versatility in satellite operations.
