01 Increasing Demand for Large Constellations for Smaller Telecom Satellites in Low Earth Orbit (leo) The low Earth orbit (LEO) is now attracting constellation companies and becoming crowded. Constellation operators are attracting investors in the space industry, creating the demand for various satellite components needed to operate these satellites in LEO efficiently. There are many reasons for placing small satellite constellations in LEO, as they are lighter and have low launch costs.The satellite's electric propulsion systems provide the satellite with collision avoidance, station keeping, orbital maneuvering, and de-orbiting. The satellites are serially produced for the constellations and incorporate electric propulsion systems while reducing the mass and launch cost and increasing the mission duration. Satellite operators are slowly transitioning from chemical to electric propulsion, and satellite electric propulsion companies are advancing their technologies to be more efficient and reliable. The key participants in the satellite electric propulsion industry are SpaceX, OneWeb, Amazon, and Boeing. These industries are in the race to provide space-based internet services through the LEO satellites constellation boosting the satellite electric propulsion market growth which substantially incer
02 Rising Research and Development Activities for Building Low-Cost and Efficient Propulsion Systems for Satellites There is continuous research on electric propulsion (EP) system technology to make it more efficient and cost-saving while reducing the size of the thrusters. The expensive part of the satellite electric propulsion system is the fuel, and the most common propellant used is xenon gas because it has a high atomic mass and low ionization threshold. Xenon has plenty of benefits but is an expensive gas rare in the Earth’s environment. This has driven the need for research on alternative and more sustainable fuels for electric propulsion.For instance, in November 2021, ThrustMe, a France-based deep tech company, developed and successfully demonstrated an iodine ion thruster that uses a solid form of iodine as a propellant. It is almost 50 percent more efficient, cheaper, and abundant than xenon. Electric propulsion is increasingly being deployed in the commercial satellite market, and there are many flight heritages for this propulsion technology. This shift in the industry from chemical to electric propulsion escalates the demand for efficient thrusters and initiates more advancements in EP technology, driving market growth.
01 Integration of Electric Propulsion Results in A Growing Power Budget The power components are an essential part of satellite electric propulsion components. It comprises solar panels, batteries, and a power processing unit (PPU), and power electronics. The power components have many functions, such as stepping up and down the voltage to provide a wide voltage range and monitoring the power supply to the electric propulsion system.The satellite operators are now interested in integrating electric propulsion systems into their satellites which automatically increases the need for more powerful components to run the propulsion systems onboard effectively and efficiently. This requirement for more powerful components comes with a high-cost tag attached to them and increases the power budget of the satellite operator. Due to the increasing power budget, more batteries and broader solar panels are integrated, resulting in a heavier satellite. In addition, expensive equipment adds to the manufacturing cost, and heavier/bulky satellite adds to the launch cost. This constraint will keep some small satellite operators from deploying electric propulsion systems on their satellites.
01 Scalability Advantage in All-Electric Or Hybrid Propulsion Satellite electric propulsion suppliers can target diverse customer groups when providing an all-electric satellite platform. There are generally three types of satellite configurations: chemical propulsion, all-electric propulsion, and hybrid (both chemical and electric propulsion). These configurations change for the different types of missions. As a result, when a satellite maker provides a platform that can be wholly electric, entirely chemical, or hybrid, it can serve a variety of satellite operators with varying mission needs.The same satellite platform can do a lighter mission when reducing costs or a complex task when adding more payloads to the satellite. This creates an opportunity for the satellite manufacturers to achieve revenue by providing various satellite platform variants to the satellite operators' diverse mission requirements.
