New Release Announcement - EOCFI v4.21

Earth Observation Mission CFI Software v4.21 has been released!

The latest version can be downloaded here with the detailed release notes available here.

User registration is required. Please find detailed instructions here.

The following is a summary of new features and problems solved in Version 4.21.

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

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

The new EO Orbit and Attitude Adapter v1.2 (for the Mission CFI Software) has been released!

Earth Observation Mission CFI Software v4.20 has been released!

The latest version can be downloaded here with the detailed release notes available here.

User registration is required. Please find detailed instructions here.

The following is a summary of new features and problems solved in Version 4.20.

Added support for new ESA missions (Sentinel-6, CIMR, ROSE-L, CHIME, CRISTAL, CO2M, LSTM, FORUM)
Upgraded EOCFI dependencies
Modernized generation of Swath Control Files
Replaced static sized arrays (XF_MAX_ARRAY_SIZE) with dynamic arrays
Added support for CCSDS Attitude Ephemeris Message (AEM) TXT and XML
Updated computation of satellite altitude to improve support for MEO satellites
Updated maximum allowed time gap between OSVs for MEO satellites
Enabled the use of SP3 files for LEO satellites

Corrected generation of Mean Keplerian elements from TLE
Enabled to statically set throwWarn = true to allow warnings in object constructors
Enabled use of XO_SEL_TIME when initializing Orbit using Doris Navigator files without J2000 packets
Corrected const qualification of OrbitId::osvCompute
Optimized #includes in public headers
Corrected memory leaks when calling xp_target_extra_vector
Corrected segmentation fault/internal error when initialising orbit with specific MLST drift values
Correct EO_OPER_INT_DEMCGF_03*.XSD to avoid demanding presence of optional fields
Corrected memory leaks when assigning CfiId derived objects
Corrected the internal convention of DEM tiles
Corrected calculation of ANX_MLST when calling xo_orbit_info with ROF
Corrected segmentation fault/internal error when calling xv_stationvistime_compute
