Add support for QZSS and IRNSS time scale #210
Comments
QZSS seems pretty straightforward: it seems like a new variant could be added and every operation on that time system would just use the same path as GPST. Is that correct? IRNSS time is definitely a bit more complicated, especially for the week calculations. I'll note that this change will require adding |
Yeah QZSS should have some operations as GPST. Good idea on |
The two time scales from RINEX 4.0 used in https://github.com/gwbres/rinex/ that is not supported by
TimeScale
is the QZSS and IRNSS System Time. I would like to make a feature request to add it.The QZSS System Time has the same offset from TAI as the GPS Time Scale, however technically it is its own time scale as they have their own set of master clocks. Per the QZSS ICD https://qzss.go.jp/en/technical/download/pdf/ps-is-qzss/is-qzss-pnt-004.pdf
The IRNSS System Time has a 13 second offset from UTC. Per the IRNSS ICD https://www.isro.gov.in/media_isro/pdf/Publications/Vispdf/Pdf2017/irnss_sps_icd_version1.1-2017.pdf
