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 400 Hall Effect Thruster (HET) has been designed to perform orbit and attitude control tasks on micro and mini satellites. Its design, based on permanent magnets, is conceived to be installed onboard of Telecommunication and Earth observation platforms. In particular, it is in the forefront of Low Power Hall Effect Thrusters (LP-HET), thruster class especially suitable for small satellites where power and mass budgets are strongly limited.
