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.
