OSNMAlib - Input: Galmon

The purpose of this website is to provide an easy way of looking at the OSNMA related data transmitted by the Galileo satellites. It runs OSNMAlib in the background.

The last 12 OSNMA subframes processed by OSNMAlib are available in format at this [endpoint]. To understand the file, we also provide a [html|json].
The raw navigation data bits for the last 12 sub-frames are available at this [endpoint].

For more information about what is displayed in each field, take a look at the legend.

This board uses the galmon network as input for the navigation data. Galmon is a very cool project where navigation data from multiple receivers around the world is aggregated and distributed. However, there are some synchronization problems with having such a heterogeneous input source.

Legend

Colour Codes

In general, green means available, grey inactive and red missing. The difference between inactive and missing is if we were expecting that item or not.

Additionaly, each ADKD type is encoded using a different colour. The ADKD type is relevant both for the tag type and the authenticated data.
The 4 ADKD types are: ADKD0, ADKD2, ADKD4, and ADKD12.

A dummy tag (indicated by a COP value of 0) is represented using a stripped pattern on top of the ADKD colour. Dummy tags do not authenticate data.

Tag Verification Inputs

A satellite card is created for each satellite seen in the last 30 seconds subframe.

Global Authenticated Data

This section is static: it always shows all satellites defined in the European GNSS Service Centre, regardless if they are currently in view of the receiver or not.
However, note that some satellites may be not operational or may not authenticate their own navigation message (e.g. SVID 14 and 18).
For precise information, check the gsc-europa website.
