The following is a summary of new features and problems solved in Version 4.21.
New Features & Improvements
- Optimisation of EOCFI library size
- EOCFI C reduced from ~1.5GB to ~210MB
- EOCFI C++/JAVA reduced from ~150MB to ~60MB - Optimisation of precise propagator runtime performance
- runtime improved by 100x - Enabled use of custom SP3 satellite identifiers
- Optimisation of memory used by DEM tile cache depending on height type
- only the strictly necessary memory is used for int16/32/64 and float32/64 pixel size - Enabled loading of overlapping Attitude data files
- Optimisation of loading orbit data with time/orbit number filtering in xd_read_orbit_file/xo_orbit_init_file
- Enabled Model parameters specification using both numerical and textual values in Attitude and Swath definition files
Bug Fixes
- Corrected calculation of Target-to-Sun visibility flag
- Corrected “maximum iterations reached” error in xo_position_on_orbit_to_time
- Corrected memory leaks when loading IERS bulletins in xl_time_ref_init_file
- Corrected failure to compute valid solution in xp_target_range
- Corrected memory leaks when using precise propagation in xo_osv_compute
- Corrected internal memory management that caused EOCFI Java examples to crash on Windows
- Corrected LoS intersection with DEM calculation that resulted in occasional positive/negative height spikes
- Corrected memory leaks related to copy constructors/destructors in EOCFI C++
- Corrected calculation of absolute orbit number when initializing orbit with EOM file
- Correct handling of Fixed Header in EOCFI Java (i.e. ensure all fields where properly set)
- Correct rotation matrix to quaternions calculation that returned NaN
- Correct critical failure when calling xv_timesegments_compute_* function with uninitialized Orbit Id
- Correct handling of -fit_mode and -tstep options in gen_tle tool
