• Updated eclips routine with Galileo and Beidou models (2017)
  by J. Kouba

• Updated eclips routine with Galileo and Beidou models (May 2017)
  by J. Kouba , Simon Banville of NRCan has found two mistakes in the Feb 2017 eclips version. First, that for Beidou IGEO and MEO eclipsing a wrong beta angle limit of 2 deg , rather than the correct 4 deg, has been used. Secondly, an unused (dead code), pretending to GAL eclips times, has not been removed/cleaned up. Both mistakes are corrected in the May2017 version.

• Updated eclips routine with further refinements to the Beidou models (Dec 2017)
  by J. Kouba, The updates are related mostly to Beidou and the rest of GNSS are not affected, except for yaw rate and bias parameter inputs, which may be useful for GPS II/IIA/IIF. So one can now use different yaw rates and/or biases if better ones are available, instead of the hard coded ones.
