New Release - EO Orbit and Attitude Adapter v1.0

The EO Orbit and Attitude Adapter has been released and can be downloaded from this page.

The Adapter is part of the Earth Observation Mission Software Suite. It is a tool / library that generates Orbit and Attitude files compliant with EOCFI format using data extracted from one or more binary files, for example files containing Telemetry packets including Orbit and Attitude information such as NAVATT packets. Orbit and Attitude files can then be ingested by EOCFI functions within a user application. The Adapter can be used as a command line program or as a software library within a user application.

The Adapter uses the DFDL4S library to parse the data. The input data file format is defined by a Data Format Description File written according to the Mission Specification Schema format that is based on the standard Data Format Description Language (DFDL). 

New Release Announcement - EOCFI v4.12

Version 4.12 (C, C++, Java Libraries) of the Earth Observation Mission CFI Software (v4.X branch) has been released and can be downloaded here.

Release Notes are available here.

User registration is required. Please find detailed instructions here.

The following is a short list of new features and problems solved:

 New Features

• xl_time_ascii_to_ascii function: 9999-12-31T23:59:59 (and similar) is now accepted as End of Mission string
• Improvements in run-time of xp_target_list_inter function
• Improvements in run-time of DEM intersection algorithm
• Support for Earth Observation Ground Segment File Format Standard version 3.
• Improvements in Orbit State Vector Extrapolation
• Extrapolation enabled in Attitude / Quaternions computations
• New function for Orbit State Vector (OSV) sanity check
• New file type: Field of View configuration
• Update of Attitude Definition File format
• TLE designator updated for Sentinel-1B
• New function to set the time step used for S/C visibility computations

Major problems solved

• 647: targetReflected method: unexpected fail.
• 655: targetInter method: memory leak in Java API.
• 658: Error/Warnings reading Doris files for Sentinel-3. (this problem has been reported by the Sentinel-3 IPF Team).

New Release Announcement - EOCFI v4.11

Version 4.11 (C, C++, Java Libraries) of the Earth Observation Mission CFI Software (v4.X branch) has been released and can be downloaded here.

Release Notes are available here.

User registration is required. Please find detailed instructions here.

The following is a short list of new features and problems solved:

New Features:

• New platform: Windows 64-bit.
• Java API: upgrade to Java version 8.
• Upgrade to libxml2 version 2.9.2.
• New Missions supported: BIOMASS, SAOCOM-CS, Sentinel-5.
• Aeolus Mission: orbit parameters changed according to new orbit requirements.
• TLE designators updated for Sentinel-1A/2A/3A.
• New function to extract attitude data (quaternions or roll-pitch-yaw angles) from attitude_id.
• New function to generate attitude data (list of quaternions and roll-pitch-yaw angles).
• Support for new DEM type: ACE2 3 arcsec.

Major problems solved:

• 610: xo_orbit_id_init: crash in ANX computation (XL_Car_Kep: semi-major axis undefined).
• 630: xo_orbit_init_def: date is not set correctly.
• 631: GEO satellites: OsvComputeExtra gives wrong results.
• 633: xp_dem_init: wrong message string. (this problem has been reported by the S3 IPF Team).
• 645: xv_zonevistime_compute: wrong start/stop time with swath/zone covering pole.
• 646: Error in DEM intersection algorithm. (this problem has been reported by the S3 IPF Team). NOTE: the specific reported problem has been identified and corrected. The intersection algorithm robustness has been improved so that, in the unlikely event that the DEM intersection algorithm fails, an approximated result is provided and a warning is returned.
