Description
The continuous growth of the population of objects in Low Earth Orbit (LEO) has caused an increase of the conjunctions between active satellites and other objects, either space debris or other satellites. It is mandatory to evaluate the risk these conjunctions pose, and to design the corresponding collision avoidance maneuvers if necessary. Since several maneuvers are to be performed in the satellite lifetime, the maneuvers should consume as low fuel as possible.
OCCAM (Optimal Computation of Collision Avoidance Maneuvers) is a novel software tool aimed at computing minimum-fuel collision avoidance maneuvers in the short-term encounter scenario, which is generally applicable in LEO. Developed by the Space Dynamics Group of the Technical University of Madrid, it employs advanced modeling and optimization techniques, which make it an extremely fast and robust design tool. OCCAM features an extensive set of input parameters, different optimization strategies and output options to provide a high design flexibility for the user. Several methods of collision probability computation are also supported. Its user-friendly graphical interface and intuitive design logic make it really straightforward to master even for non-experts, and it can be employed either as a standalone tool or in conjunction with other satellite operation planning frameworks.
In an increasingly complex operational scenario, OCCAM does what other collision avoidance planning tools do but in a fraction of their computation time, making it a fast and reliable design and planning tool for the space operators seeking to minimize the cost of their collision avoidance maneuvers.
A trial version of this tool called OCCAM lite is available on-line for the interested potential user at the web page of the Space Dynamics Group: http://sdg.aero.upm.es/index.php/online-apps/occam-lite. The fact that this tool is capable of running in a web-browser (either on workstations or mobile devices such as tablets or smartphones) is a proof of the outstanding velocity of this software.
