We present a constellation of three satellites capable of remote sensing operation at an orbital altitude as low as 297 km thanks to the use of an electric propulsion system for orbit maintenance. The mission architecture and the spacecraft configuration are such as to fit a multiple launch on a Vega small launcher. Orbit simulation is carried out using a proprietary code for low-thrust trajectory dynamics. Propellant mass and maneuver durations are computed for the main orbit control tasks and the system mass budget is evaluated for the payload, propulsion and power subsystems. We conclude that low-altitude remote sensing can be effectively and carried out with a constellation of three small spacecraft equipped with electric thruster, using present-day technology.

Abstract
We present a constellation of three satellites capable of remote sensing operation at an orbital altitude as low as 297 km thanks to the use of an electric propulsion system for orbit maintenance. The mission architecture and the spacecraft configuration are such as to fit a multiple launch on a Vega small launcher. Orbit simulation is carried out using a proprietary code for low-thrust trajectory dynamics. Propellant mass and maneuver durations are computed for the main orbit control tasks and the system mass budget is evaluated for the payload, propulsion and power subsystems. We conclude that low-altitude remote sensing can be effectively and carried out with a constellation of three small spacecraft equipped with electric thruster, using present-day technology.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
