ORBITM stands for the Orbit Maintenance and Propulsion Sizing Tool, and it is an open-source, easy-to-use, free-ware orbit maintenance simulator and propulsion sizing tool, for anyone with a Python 3 installation. The software comes with its own built-in orbit decay model and maintenance simulator, a life-time estimator, and it is also interface-able with AGI’s Systems Tool Kit (STK) as an alternative mode of simulation.

The objective of ORBITM is to allow for a quick sizing of low Earth orbit (LEO) mission lifetime, while sizing the mission against propulsion units of the user’s choosing. The user may input into the UI their orbital parameters, spacecraft properties (mass, area, drag parameters etc), and the software will compute your desired ΔV necessary for the mission, track the altitude profile over time, and plot the thruster-fuel profile that satisfies the orbit maintenance needs of your mission.

Document tree for ORBITM is listed out below.
