I fed those into gpsd, and this is the result:

$GPRMC,120212.953,A,5126.1926,N,00758.5483,E,0.01,0.0,180800,,,A*5F
{"class":"TPV","mode":2,"time":"2020-04-03T12:02:12.953Z","ept":0.005,"lat":51.436543333,"lon":7.975805000,"track":0.0000,"magtrack":2.4295,"magvar":2.4,"speed":0.005}
$GPRMC,120213.953,A,15335.322,N,00758.5483,E,0.01,269.58,180800,,,A*60

So gpsd DID filter out the bad data.

You are looking at the unfiltered bad data IN to gpsd.  The data OUT
of gpsd is properly cleaned.
