“…Their approach, shared with all the stakeholders of the space sector, is articulated along three complementary axes. The first axis aims at avoiding collisions by improving the surveillance systems (for instance, USSPACECOM operates a network of 29 observation means 8 ) and by carrying out avoidance maneuvers (on average, there is one maneuver per year and per satellite, and the international space station carries out about two maneuvers per month) (Bonnal et al (2020)). The second axis seeks to reduce the production of debris, by (i) protecting the satellites from the effects of collisions (in particular by shielding 9 and a reflection on the architecture and materials used in the satellites), and (ii) designing space operations so that they do not produce new debris (e.g., prohibition of explosions in space, controlled atmospheric re-entry of the satellite at the end of its life, or placing it in a graveyard orbit).…”

“…Electric propulsion (EP) has higher fuel efficiency so less fuel and propellant storage is required, hence EP is more suitable for smallsats [4][5][6]. Propulsion provides smallsats with; collision avoidance [7,8], orbital manoeuvring, station keeping, orbit transfers, formation flights [9] and interplanetary trajectories as demonstrated by ESA's SMART-1 mission [10] and the Mars Cube One mission which was successfully completed this year [11]. Traditional smallsats orbit in low Earth orbit (LEO) and rely on reaction wheels and magnetorquers to provide attitude control and stability [12] for instruments.…”

Electric Propulsion Methods for Small Satellites: A Review

Over 2500 active satellites are in orbit as of October 2020, with an increase of ~1000 smallsats in the past two years. Since 2012, over 1700 smallsats have been launched into orbit. It is projected that by 2025, there will be 1000 smallsats launched per year. Currently, these satellites do not have sufficient delta v capabilities for missions beyond Earth orbit. They are confined to their pre-selected orbit and in most cases, they cannot avoid collisions. Propulsion systems on smallsats provide orbital manoeuvring, station keeping, collision avoidance and safer de-orbit strategies. In return, this enables longer duration, higher functionality missions beyond Earth orbit. This article has reviewed electrostatic, electrothermal and electromagnetic propulsion methods based on state of the art research and the current knowledge base. Performance metrics by which these space propulsion systems can be evaluated are presented. The article outlines some of the existing limitations and shortcomings of current electric propulsion thruster systems and technologies. Moreover, the discussion contributes to the discourse by identifying potential research avenues to improve and advance electric propulsion systems for smallsats. The article has placed emphasis on space propulsion systems that are electric and enable interplanetary missions, while alternative approaches to propulsion have also received attention in the text, including light sails and nuclear electric propulsion amongst others.

“…Kim et al [27] used genetic algorithms to tackle the case where several debris approach the satellite in a short period of time, identifying limitations in the use of tangential maneuvers to deal with this scenario. Furthermore, several authors are investigating the possibility to perform so-called just-in-time CAMs between two debris, using external actions such as lasers or clouds of gas [28,29].…”

An analytical formulation for collision avoidance maneuvers involving a spacecraft and a space debris is presented, including solutions for the maximum deviation and minimum collision probability cases. Gauss's planetary equations and relative motion equations are used to map maneuvers at a given time to displacements at the predicted close approach. The model is then extended to map changes in state between two times, allowing one to propagate covariance matrices. The analytical formulation reduces the optimization problem to an eigenproblem, for both maximum deviation and minimum collision probability. Two maximum deviation cases, total deviation and impact parameter, are compared for a large set of spacecraft-debris conjunction geometries derived from European Space Agency's Meteoroid and Space Debris Terrestrial Environment Reference (MASTER-2009) model. Moreover, the maximum impact parameter and minimum collision probability maneuvers are compared assuming covariances known at the maneuver time, to evaluate the net effect of lead time in collision probability. In all cases, solutions are analyzed in the b-plane to leverage its natural separation of phasing and geometry change effects. Both uncertainties and maximum deviation grow along the time axis for long lead times, limiting the reduction in collision probability.
