STAVOR stands for Spacecraft Three-dimensional Attitude Visualization using Orekit library.
It is an application for smart-phones and tablets used to visualize the attitude and orbit information of a simulated spacecraft in three-dimensional and cartographic environments.
STAVOR allows you to learn and teach about space mechanics in new-generation devices, mobile and tactile. But STAVOR can also enhance your space mission simulations with visualizations focusing on some not-so-intuitive properties of trajectories and attitude.
The 2D cartographic vizualization shows the sub-satellite trajectory as well as day/nigh separation. It includes ground stations visibility circles but dynamically grow and shrink them depending on spacecraft altitude. This helps understand operational constraints in highly elliptical orbits.
The 3D vizualization is spacecraft-centric. It was designed to visualize attitude problems. Users see the bodies and their directions around the spacecraft, from its own perspective. It is different from regular 3D space simulations that show the spacecraft flying around a central body. In this mode, it is possible to display the evolution of many geometrical properties like angles between vectors or between planes.
There is a list of available missions where you can create and modify your space missions.
The visualization module can be connected to an external simulator through a network using sockets. The information expected to be received is the serialized Orekit object SpacecraftState, which includes all the information of the simulated spacecraft.
The simulator included in the application is powered by the open-source library Orekit.
