Warning: I found an error if the DR position is on the southern hemisphere. The PUB249 pdf files did not show this error and are correct (as far as I checked). All Revisions 8+ and the Windows release have been fixed. This Python TK application calculates a good set of stars for a 3 star fix, makes all calculations similar to the FAAs Celestial Computation Sheet (see FAA doc FAA-H-8083-18).

This C++ library allows to compute the Minimal Orbital Intersection Distance (MOID) between two elliptic confocal orbits using the method by Kholshevnikov & Vassiliev (1999), Cel. Mech. Dyn. Astr., 75, 75. The implementation of the method is described in (Baluev & Mikryukov 2019), Astronomy & Computing, 27, 11. It employs numeric error control and deals carefully with nearly degenerate cases (like almost circular and almost coplanar orbits). Library also includes auxiliary functions. The code was developed and tested with GCC, though it should be usable with any other C++-compatible compiler. See README.

...These groups will be perturbed by varying their positions relative to the rest of the system (rigid-body-motions) and/or by adding Zernike shape deformations on their front surface. After a certain perturbation is applied, ZOS runs (sequential) raytracing to compute the optical performance such as centroid displacement or wavefront error.

SoundStepper is a "100% software" telescope controller, for Windows, using audio hardware to control step motors at real time. All it requires to operate are external step motor drives, which can be a commercial "pulse/direction" drive or analog current amplifiers. Documentation: http://soundstepper.sourceforge.net/

This is clone of the Celestron PECTool used to upload, download and manipulate PEC data. It is intended to work with Celestron Nexstar mounts like NexStar GPS, NexStar GPS-SA, NexStar iSeries, NexStar SE Series, NexStar GT, Advanced-VX, Advanced-GT and CGE mounts. Communication to the hand control is 9600 bits/sec, no parity and one stop bit via the RS-232 port on the base of the hand control. To build it libnexstar version 0.11 or newer is needed, which can be found here:...

QDeblend3D is a dedicated software tool for the deblending of QSO and host galaxy emission in 3D datacubes obtained with optical IFU spectrographs. The GUI allows to control the process and to visualize the results with an integrated cube viewer.

EQAlign born as a software that assists to align a German Equatorial Mount (GEM) exactly to the Earth polar axis. Today, in adition to polar align feature, EQAlign is a full featured astronomical software.
