Units for ephemeris don't match about ogrp

[iiskumari]

The issue was correctly recognized. The tests of ogre ephemeris output does shows radian units.
We observe at different systems and sources, units of some of the ephemeris parameters.

systems: Units:
ogre - radian
ogrp - semi-circles
GPS_ICD - semi-circles
Rinex - radian
Spirent - semi-circles
Groov's book - radian
http://gps.sref.info/course/2d3.html : example out of GPS ephemris from GPS standard receivers which uses radian. if we follow the ogrp schema as semi-circles unit, then we have to consider the similar change in rtk and in ogre. This is not that usefull and lof of effort to change the unit only to match the schema. Hence, we change the ogrp schema to radian. please confirm, if you also agree with it.

I agree. Most (if not all) calculation are done in radians anyway, so changing the description to radians is the best solution from my point of view.

[iiskumari]

yes, that's right. Hence, I proceed with the ogrp schema change.
