Thanks @jdatalog if you can post an example file here and the initialization code you've used I'll try to reproduce the bug

jdatalog commented 6 years ago

Have not my code here but it's the same as in postprocessing wiki.

Something like : masterIn = new RinexObservationParser(new File("axpv241z.18o")); masterIn.init();

There is an exception because the code try to convert space caracter to integer (as number of type of number of observation) in the the second "TYPES OF OBSERV" line : S2 L5 C5 D5 S5 L7 C7 D7 S7# / TYPES OF OBSERV

thank you @jdatalog I'll have a look this weekend

mmm, yes, I can see the problem, multiple lines. Not sure it's an easy fix. the parser is designed just to handle one line at the time
