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.

The HT 100 Hall Effect Thruster (HET) is the smallest and lowest power HET ever developed in Europe, whose performance and characteristics represent the state-of-the-art of this technology. Based on permanent magnets, the HT 100 HET is designed to perform orbit control tasks on micro-satellites and AOCS tasks on mini-satellites. The HT 100 thruster unit and all the key sub-system components are fully based on European, ITAR-free technologies. The HT 100 thruster unit can be offered with its HC 1A S-type hollow cathode, 300 W max PPU and dedicated fluidics based on flight-proven valves.
