A Lambert-orbital boundary value problem can be stated as"Find the orbit/trajectory of a spacecraft that flies from position [r1] to [r2], taking a time [tf] and making [m] complete orbits before arriving at [r2]. "The solution to each Lambert-problem is NOT unique; one can travel to [r2] via the...

PyxisControl is an astronomy utility which can control Optec's Pyxis 2" and 3" Field Rotators. Additionally it can link to Software Bisque's TheSkyX Pro to control the orientation (Position Angle) of a selected Field of View Indicator (FOVI). These will be synchronized when both are connected to...

The Ejs Celestial Globe model simulates the Two Sphere Universe theory of the Ancient Greeks. This theory supposes the stars to be fixed on the surface of a Celestial Sphere, with the spherical Earth at the center of this sphere. The simulation shows the motion of Sun and stars in this model, as...

The Astronomical Parallax 2D Model illustrates the phenomenon of parallax in astronomy. Parallax is the apparent displacement of an object relative to the background that is caused by the motion of the observer (rather than the motion of the object itself, or of the background). This simulation...
