Thank you to Kazuya for submitting an aircraft tracking app that he's created for use with RTL-SDR dongles and dump1090. The program currently exists only as Visual C++ code and is documented in Japanese, so it may be somewhat niche and intended for advanced users to try out. Kazuya writes:

I live near Tokyo Bay, so I enjoy watching the takeoffs and landings at Haneda Airport.

The unique feature of this app is that it visualizes the descent angle, which is difficult to see on a flat map.

This app has not been available for distribution. If you are an intermediate Visual C++ user, you may be able to rebuild or modify the app.

Topographical and landmark information is in text files, allowing you to customize area information in more detail for your airport.

(3) Glide_Path
Can be built independently.

Execution Environment
Copy the folder (ADS_GLIDE_PATH) to C:.

・When using an ADS antenna
Install the ADSB antenna and driver software on your PC.
(As a mid-way test, you will be able to listen to radio broadcasts on your PC.)
Launch dump1090_with_StdinAPL1.bat to ensure that tmp_ADS_B-0000****.txt is continually generated in C:\ADS_GLIDE_PATH\tmpDataFolder.

- Without an ADSB antenna
You can use the data in DemoData (approximately 30 minutes, 6,000 entries) to check the software's operation.
(Procedure) Launch Glide_Path.exe and, on the parameter change screen, set [S001] Demo Mode to 1.
Exit Glide_Path.exe and restart it. The Start Demo button will appear; press it.

(4) Stdin_Apl1
Can be built independently.
This is an auxiliary program when using the ADS antenna described above in (3). Stdin_Apl1.exe
This program parses the standard output of dump1090.exe, provided by the ADS antenna manufacturer, into a text file and processes the data so that it can be read by Glide_Path.exe.
