- Add ability to build Trajectory from BSP - Include line of sight (eclipsing) computation in OD measurements
- RIC errors are still quite large due to a modeling error - Residuals are too large

To-do: investigate why the measurement noise values are so low when plotting the residuals. Also dive into the ODTK math spec again for the measurement ratios to see in which cases these get rejected. I think my logic matches that of odtk, but I should double check that. In my tests tonight it seems that the filter is overzealous in rejecting measurements. |
