NMEASIM sends NMEA 0183 sentences to a navigation SW such as OpenCpn via a serial com port or a UDP channel. These NMEA sentences simulate data coming from a GPS(sentence $GPRMC...) and an AIS receiver(sentence !AIVDM...) All the parameters : name, mmsi, initial position (lat/long), COG, SOG for my boat as well as for AIS targets, and I/O configuration (com port...) can be edited in the 'datasimul.json' (file created by the app with default values in V1.0) Just Download the nmeasim.exe file (green button above) and launch it. Be patient for a few seconds if you have a slow PC! Go to the 'Files' tab to look at the readme file and download any additional file if needed.

This C++ demo allows users to interactively explore a quadtree's behavior. For this purpose the demo uses a quadtree data structure based on axis-aligned bounding boxes to speed up the search for triangles in a mesh. Depending on a search point all triangles of a quadtree's region are retrieved and relevant information about the search is shown. Quadtree creation can be parametrized by three parameters: - Maximum tree depth. - Maximum number of triangles per region. - Percentage...

...This software is grounded on the works lead by Sibertin-Blanc and Roggero on the formalization of the Sociology of Organised Action [Crozier and Freidberg]. Visit the homepage of the project on soclabproject.wordpress.com for tutorials, examples and further theoretical position.

...It computes ship motions for monohulls including sailing boats. PDSTRIP has been abandoned by its initiators, who do not wish to be contacted with use questions. The position of maintainer is vacant.

GRAVITY ALPHA is developed for visualization of gravitational force effects between (two) objects. In order to predict/calculate object properties in future time (of course, within the limits of calculation) one need initial position and speed at some initial moment of time . For calculating positions and velocities, numerical method for solving differential equations is used. There is no limitation in parameters - object will behave just like they behave in the real world. The only thing which is not ‘real’ is an option to increase the object sphere beyond physical meaning (unrealistic small density). ...

...It is particularly useful for users that generate ns-2 trace files with other tools such as VanetMobiSim or SUMO (Simulation of Urban Mobility). With ns-2 Trace Toolkit, users can debug their trace files by generating histograms for: (1) node speed, (2) node x-position, and (3) node y-position. These histograms can give hits about concentration of nodes. Additionally, the tool allows users to simulate the movement of the nodes, in different modes: step-by-step and continue motion. During the simulation, the information of each node (speed and position) is shown. Finally, basic manipulation of trace files are also available in the tool. ...

3D vehicle simulator in which vechicle's configuration as a whole (articulated body) , is represented by a 'vector' of generalised coordinates. so concepts like usual position and orientation of main body and wheels is all defined by the generalised coordinates.Using Lagrangian dynamics, theese coordinates are evolving in time in a realistic manner according to F=ma but as if there were also all constraint forces concretasing the presence of joints: hinge, prismatic, rigid connection, etc. all derivatives are done with finite differences, so it's all simple. in 3 videos I explain all the mechanics and its simulation up to this simple but pow method.Pure Lagrangian mechanics until now has not been used much or at all,in simulation videogames,but i decided to try it because it was promising, very simple compared to the fnal results, and there was not much docu on its use in simulation games: this lack was completed now. ...

JSatTrak is a Satellite tracking program written in Java. It allows you to predict the position of any satellite in real time or in the past or future. It uses advanced SGP4/SDP4 algorithms developed by NASA/NORAD to propagate the satellite orbits.

Desktop gadget (Windows only). The simulation of a real horizontal sundial, dependent on a geographic position (latitude). Size can be chosen between big and small. It can use current (computer) time, or user-specified date&time.

This package allows you to create virtual rubik cubes and move their faces. Moreover you can see at every time the current position of the cube and find its solution. Visit http://www.hcroboting.com for more information

This project aims to provide libraries in a few languages which allow for NORAD general perturbation element sets to be used in calculating the position and velocity of space objects.

Pysolar is a Python library for calculating the position of the sun relative to the earth as a function of latitude, longitude, and time. There is also code included for other problems related to the development of photovoltaic systems. Still in alpha.

...c) a rendez-vous and docking module that uses Clohessy-Wiltshire equations to optimize rendez-vous and docking maneuvers, assess the effect of the target's gravity field and analyze the effect of position and velocity uncertanties. d) a Simulink ADCS simulator with a focus on control law design.
