I don’t think the first one is a bug in the tutorials. The values in the Sinex file for station velocity are given in m/y, so the conversion is needed. The bug is in the Orekit documentation. Two options are possible:
- Update the documentation to say that the return value is in m/y
- Don’t change the documentation and perform the conversion when parsing the Sinex file in Orekit.
Since 11.0, utility classes where developed to perform unit conversions. Therefore, I prefer the second option. In addition, we usually return SI-based values in Orekit.
Also, the analysis centers producing Lageos2’s orbit products generally not estimate the reflection coefficient. The value for Lageos2 is well known and equal to 1.13. The reason why we don’t active the solar radiation pressure for the Lageos2 tutorial is because it increases the computation a lot (i.e., ~16sec without SRP, ~69sec with SRP, and ~98sec with estimated SRP) without big improvements in the orbit solution.
For the second issue, do you have a reference?
