Hall Effect Thrusters (HET) are the technology of choice for large GEO telecoms and other medium/high ΔV missions, quickly gaining acceptance for LEO applications as well. Thanks to their high specific impulse and proven reliability, HETs are also employed for space exploration (ESA SMART-1). These thrusters can work with satisfactory efficiencies over a power range from around 100 W up to tens of kW.

HT 5k Hall Effect Thruster (HET) has been designed to meet the requirements of modern communication and navigation satellites, performing propellant-saving LEO-GEO/LEO-MEO transfers as well as station keeping tasks on large geostationary platforms. Relying on Sitael’s heritage in HET technology, HT 5k is a high – efficient thruster with a magnetic system based on coils. Designed to be fed with Xenon, it can be effectively operated also with alternative propellants such as Kr maintaining excellent performance.
