OSNMAlib - Input: Septentrio Receiver @KULeuven

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 input from a Septentrio receiver located at the ESAT department of KU Leuven. You can expect to have a very clear open sky view, with satellites lower than 10 degrees of elevation.
Special thanks to Septentrio for the receiver and to Franco for the help setting the antenna up in the tower.

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 3 ADKD types are: ADKD0, ADKD4, and ADKD12.

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 (e.g. SVID 14 and 18). For precise information, check the gsc-europa website.
