AntexReader fails at Multi-Epoch listings
Posted on 28 Aug, 2014 by StefanJunker
Dear all,

I am trying to retrieve APC information from an Antex file (igs08.atx) using the gpstk::AntexReader class the following way:

AntexReader ant;
ant.open(antFile);

SatAnt = ant.getAntenna(id, time );

ant.close();

In the AntexReader.cpp (line1350) the epoch comparison always leads to an unknown error.

I have debugged this part and the times (epochs, antenna.getAntennaValidFrom(), antenna.getAntennaValidFrom()) show right results, but the logical operation failes in line 1350 using GPS Satellite G11 on L1 frequency for JD 2454697.5.

Thanks for the help. Stefan

novaRinex converter needs updating
Posted on 14 May, 2014 by RobertSchaefer
HI,

I have a novAtel receiver version OEM6, but the novaRinex Converter only supports versions for OEM2 and OEM4.

Who administers maintenance of gpstk?

How long will it take for version OEM6 to be supported?

thanks, bob schaefer rps@haystack.mit.edu

Rinex cut-off angle
Posted on 25 Feb, 2014 by DanielMoreira
Hello

I´ m just started to use GPSTK!

I would like to know if it's possible to I generate from a RINEX and ephemerides file one new RINEX file with satellite cut-off angles of X degrees.

I tried to use two commands without success:

PRSolve --obs temp3320.09o --BCEpast temp3320.09n --forceElev --elev 30 --out test.13o

Exception: text 0:CommonTime objects not in same time system, cannot be compared: UNK = UTC location 0:/home/bparsons/git/gpstk/dev/lib/TimeHandling/CommonTime.cpp:362 location 1:/home/bparsons/git/gpstk/dev/apps/positioning/PRSolve.cpp:1185

and

ResCor? -IFtemp3321.09o --nav temp3320.09n --RAIM --MinElev 15 -OFteste

It's ok , but no cut-off was been applied,

Can anyone help me?

Thanks in advance
