Suggestion of enhancements for SP3Parser
To be more smart, the followings changes are suggested to fit sp3 files provided by ILRS ACs(ASI,BKG,DGFI,ESA,GFZ,JCET,NSGF, and ilrsa, ilrsb, https://ilrs.gsfc.nasa.gov/data_and_products/products/index.html#s2, ftp://edc.dgfi.tum.de/pub/slr/products/orbits/):
(1) DATA_EPOCH: use the rest as seconds.
final double second = Double.parseDouble(line.substring(20, 31).trim());
==>
final double second = Double.parseDouble(line.substring(20).trim());
(2) HEADER_COMMENTS: both “%/*” and “/*”
HEADER_COMMENTS("^/\\*.*")
==>
HEADER_COMMENTS("^[%]/\\*.*")
(3) clock record in DATA_POSITION and DATA_VELOCITY:
// clock (microsec)
pi.latestClock = line.length() <= 46 ?
DEFAULT_CLOCK_VALUE :
Double.parseDouble(line.substring(46, 60).trim()) * 1e-6;==>
// clock (microsec)
pi.latestClock = line.trim().length() <= 46 ?
DEFAULT_CLOCK_VALUE :
Double.parseDouble(line.substring(46, 60).trim()) * 1e-6;There is already a topic in forum details.
Additional, there maybe no EOF. I've no idea how to handle it.
