v0.8.0: Hifitime & signal processing

[gwbres]

Special thanks to @larsnaesbye, @ChristopherRabotin and my friend Julien for their support and contributions to this release.

• Introduced a Code of Conduct

• package

  • rinex::prelude introduced to import major structures easily
  • rinex::sampling dedicated pkg
  • rinex::processing dedicated pkg
  • rinex::gnss_time dedicated pkg

• parser

  • Navigation Orbits: SBAS identification issue fixed
  • fixed a faulty 1 byte offset when parsing NAV epochs
  • FNAV frames were not correctly parsed
  • INAV frames were not correctly parsed
  • add more thorough CRINEX1 and 3 decompression tests
  • improved CRINEX decompression: some compressed omitted observations were sometimes missed, due to lack of robustness

• Observation RINEX

  • phase alignment method
  • record analysis seriously improved
  • signal combination methods

• Processing & calculations

  • Geometry free signal combination
  • DCBs code biases analysis

• Epoch and Timescales

  • Library is now converted to use Hifitime Epoch.
  • subsecond precision barrier is crossed, theoretical limitation becomes 1 ns
  • Observation RINEX: 100ns precision
  • Navigation RINEX (V2): 0.1s precision
  • Time scales (TAI, GPS, GAL..) naturally supported
  • Leap seconds naturally supported
