slewpy

slewpy is a Python package that allows the simulation of the science operations of an astrophysics space satellite mission. slewpy allows users to specify an astronomical target list with observing priorities and a satellite configuration (i.e., orbit and various satellite parameters). Taking these inputs, slewpy can be used to run a time-resolved simulation of an astrophysics mission and outputs simulated target observations given constraints such as satellite slewing rates between targets, observing time on a given target, and Sun-, Earth-, and Moon-limb observing constraints. slewpy provides the tools to test astrophysics space satellite mission designs against observing requirements for a given science case.

For more details on the project including the installation, contributing, and the getting started guide see the documentation.

Example visualization of a slewpy satellite simulation. The figure shows astrophysical transients appearing and disappearing on the celestial sphere (colored circles). Every time an unfilled circle appears around a transient, it indicates that the transient was observed by a satellite in a 600 km altitude sun-synchronous polar orbit. Shaded regions show various observing constraints: Moon, Sun, and Earth-limb constraints, as well as the high source density region of the Galactic plane. Transients are not observed when they are in one of the constrained regions.
