    Hi guys,

    I have analyzed some ADSB data and i have found some adsb message, where the latitude value is greater then 90 degrees (the rest of this data message seems to be ok). Is there anybody who made the same experience or knows, why this happens? Can i assume, that the receiver produces invalid values in this case or has swapped latitude and longitude? Or are there receivers with a non-standard latitude range, which do not match to [ -90 ... 90 ] ?

    Thanks

    Bad data coming from feeders, particularly feeders in the UK using VRS.

    Sometimes we also catch state sponsored signals interference blowing up GPS.
