This Android application process and transform the data recorded by the Multiplex Flight Recorder. This module records on a micro SD card the data circulating on the MSB telemetry bus.

This is recorded in CSV files (comma separated values), one line by sampling time, sensor values in columns separated by semi-colons (;). Such a file could be used with a spreadsheet program. But if a GPS sensor is placed on the MSB bus, the position data is inserted as lines with another format that is not sent by the return link. This application makes a separation between these two kinds of data.

Running on a tablet or smartphone, it produces files that could be viewed and analyzed with the included software modules and/or with applications available on theses devices. It could be used to browse the previously processed logs and launch the applications needed to analyze them. It acts as a bridge between the MSB format and the KML format used by Google Earth: thus the name "MSB to KML".

This is a standard Android/Java application that request only the permission to read and write files. You could have to check in the settings of the device that the installation of applications from other sources than Google Play is permitted.

It should work on Android versions from Jelly Bean (4.1) to Nougat (7.0).


The application could be compiled with AndroidStudio from the files downloaded from this repository.

Alternatively it could be obtained with the documentation from the "Releases" pages from the repository.

In each case the application package (such as Msb2Kml42.apk) should be transferred to the storage of the device (such as /sdcard/Downloads). Selecting it with a File Manager should offer the opportunity to install it.

Other applications should be installed for a better experience; all of them are free.

To look at GPS track in GPX files: GPS Track Browser and Viewer from Google Play.

To look a GPS track in GPX files and display them on off-line map overlays: OsmAnd from Google Play or OsmAnd from F-droid.

To look at GPS track in KML files: Google Earth.

To edit the configuration file: DroidEdit from Google Play.
