Satellites
The 'Satellites' tab-page is where you can choose which satellites will be plotted on the 'Satellite Footprint' and 'Satellite Track' map layers, and set their parameters.
There are over 6800 Satellite Two-Line Elements listed on the Celestrak website, each of which are used to calculate the current position of a satellite. These are automatically downloaded as needed, and the list is shown on the 'Satellites' tab-page, divided into 50 groups. Select your chosen 'Group of Satellites' in the drop-down control, click a satellite name in the Satellite List to select it, then click the 'Add Satellite to the Display List' button to add that satellite to the list of 'Selected Satellites' that will be displayed on the map. Up to eight satellites can be shown on the map simultaneously. The program will update the Satellite Two-Line Elements when a new satellite is chosen, and then automatically, every two hours.
Adjacent to each satellite-name in the 'Selected Satellites' panel is an 'Active' checkbox. This controls whether that satellite's track and footprint will be plotted on the map. If the check in the checkbox is cleared, then the satellite will still be shown in the rotating list on the Info Bar (page 'IG'), but it will not plot on the map.
Clicking a Satellite Name in the 'Selected Satellites' panel will show an additional 'Satellite Params' panel. Here you can choose the Icon that is used on the map for that satellite, and the length of the tracks: a path of negative duration (0 to 90 minutes), showing where the satellite has been during that period; and a path of positive duration (0 to 90 minutes), showing where the satellite will be during that period. You can also remove a satellite from the 'Selected Satellites' panel by clicking the 'Remove Selected Satellite' button. Note that you can't remove all the satellites: there will always be one in the list.
After selecting your satellites, close the 'Settings Menu', and open the 'Layers Menu' to enable and configure the 'Satellite Footprint' and 'Satellite Track' map layers, setting their colors and widths.
There is more satellite information available in the Info Bar page 'Satellite Data'(shortcut: 'IG'), and in the 'Satellite Data' section of the Data Bar.
The 'Satellite Data' section of the Data Bar show a small amount of data for the currently selected satellite: its current Azimuth, Elevation, and Range from the User Position, and the satellite name.
The Satellite Data page in the Info Bar lets you choose to rotate between all the available satellites, by typing the shortcut 'SA', or lock on to one specific satellite by typing the shortcuts 'S1' - 'S8'. For the selected Satellite, you will see Latitude, Longitude, Azimuth, Elevation, Range, Altitude, Speed, Footprint Radius, and a list of details for the next 5 satellite passes over your home location.
There is also a Polar Plot, centered on your location, that shows the predicted path of a satellite from horizon to horizon, with details of Azimuth and Elevation plus current sun position for the next 5 passes, when the satellite will be visible at the User Location. When a single satellite is selected, the polar diagram will show a different image when the pass is active, with an orange arrow showing the current direction to the satellite. This image is not shown when rotating through 'All Satellites', as there may be more than one satellites currently over-flying the User-location. There is also a countdown timer to the next 'AOS' (Acquisition Of Satellite). When the satellite is in view, an arrow is added to the polar plot, showing the current direction to the satellite from the User Position, with a countdown timer to 'LOS' (Loss Of Satellite).
Extra details are added for the selected Satellite: Satellite Number, International Designator, Epoch, Local Sideral Time, Set Number, Inclination, Right Ascending Node, Eccentricity, Argument of Perigee, Drag Term, Mean Anomaly, and Mean Motion.
When available for the current satellite, we also show Uplink/Downlink/Beacon frequency information, plus Mode, Callsign, and Status, thanks to Mineo Wakita JE9PEL at https://www.ne.jp/asahi/hamradio/je9pel/.
You can also click any of the passes listed under 'Next Passes' to show a small window with an expanded color 3D view of the pass, in a format that is much easier to visualize. The view is centered on your User Location, and shows the arc of the pass in the sky, with a green dot for AOS (Acquisition of Satellite), a blue dot for the Mid Point, and a red dot for the LOS (Loss of Satellite). A yellow line connects the User Location to the Mid Point of the pass. There are two controls: 'Elv' that adjusts the elevation of the plot (2°-90°), and 'Rot' that rotates the plot clockwise (0°-90°)
