摘要

The considerations involved in selecting a propulsion system for the current remote sensing mission is faced with an increased number of available technologies on the horizon. rnTo respond to an increasing number of mission specific requirements, system engineers are looking at a variety of propulsive systems, ranging from monopropellant to the various families of electric devices developed and tested in space. Typically, mission design analysis suggest that there is no all time winning technology whereas, a case-bv-case analysis indicates that different technologies successfully adapt to the different mission scenarios rnThe best solutions often require that combinations of different technologies must be installed on board, thus permitting the use of the most advantageous function of each system rnTypically, technology combination increases the complexity and subsystem mass and must be analyzed more attentively before being adopted. Generally, in order to reduce the mission costs and risks and to maintain a platform recurring design, the propulsion selection is driven towards wide missions ranges utilization, possibh including a modular concept rnAdoption of an advanced propulsion system is receiving more attention due to the possible enabling factor it can offer, and in the particular case where its higher specific impulse can offer significant advantages in terms of general "cost" in comparison to chemical propulsion systems installed on the satellite The proper selection of suitable combination of mission and propulsion technology, is the key to a successful design (accounting, of course, other important factors such as recurring design constraints) There are particular scenarios where a combination of constraints in mission (as orbit, maneuvers, etc)in the Payload (with power and mass) and with the launch vehicle selection, permit the successful adoption of one system over another. These kinds of trade studies are being conducted to adapt current satellite design to the future requirements of tomorrow's missions
