QT skyplot widget to visualize relative satellite positions

Introduction

The Skyplot widget is a small QT library to visualize satellite skyplots.

INSTALLATION:

If you have a command line by your hand, do

      qmake
      make
      make install

to build and install the widgets.

This not only installs the Skyplot widget, it also installs a designer plugin.

To build the skyplot-widget with QML support, run the following:

      qmake DEFINES+=SKYPLOT_QML_SUPPORT
      make
      make install

A QML/QtQuick example can be found in examples/main.qml and examples/main.cpp.

If you ware working with the Qt Creator:

Open the file SkyplotWidget.pro and adapt the Project settings: Add a custom build step with the make argument "install". After doing the build, the resulting files get installed. On windows, the installation path is set to c:/skyplotwidget-x.x.x. This path can be adapted in src/src.pro.

If you want to include the sources directly:

You only need to include SkyplotWidget.pri in your *.pro file and you have to define SKYPLOTWIDGET_STATIC. Have a look at example/example.pro. The SKYPLOTWIDGET_STATIC disables the Q_DECL_EXPORT / Q_DECL_IMPORT behaviour for the library (only relevant for windows).

Usage:

skyplotwidget's Issues

QSkyPlotWidget Possible Upgrades

The Widget looks perfect for plotting the positions of MEO and GEO satellites. A possibly good update could be the addition of showing LEO satellite passes such as plots given by Heaven's Above (see image below). Possible C++ package for pass predictions can be found in the SGP4 package (url = https://www.danrw.com/sgp4/ ). Another functionality that might be useful in addition to the LEO passes would be an indication of when the satellites are in shadow and when they are illuminated by the sun during their pass (example: the line depicting the pass is yellow when lit and blue when in shadow). This functionality would be extremely helpful for building a list of satellites to track.
