Release Notes are available here.
User registration is required. Please find detailed instructions here.

New Features
- Consolidation of Esov scenario file, segments file exports and timeline files (SCF) regarding types of orbit configuration
- Decoupling of orbit/time range calculation conversion in orbit panel

Corrections
- ANR-428: Error message if SZA active and set to 90 deg. and ORBIT or instrument without SZA flag is ON
- ANR-431: If UTC time before Start UTC in orbit parameters panel an error message is raised and the application exits
- ANR-433: Title of Style Manager not updated when selecting certain elements in the Layer Manger (e.g POI, Borders)
- ANR-443: Rounding issue when transforming between (Start Orbit, # orbits) and UTC Start/Stop
- ANR-446: In orbit parameters panel, a change to the Abs. Reference Orbit is not persistent the first time
- ANR-448: Esov crashes if swapping from orbit parameters panel to Orbit Scenario file and Start Orbit < AbsRefOrbit in OSF
- ANR-449: Predicted Orbit File validity calculated in orbit panel doe not cover the complete file
- ANR-450: Segments not correctly placed when opening Esov scenario file
- ANR-451: Segments not correctly placed when loading Swath Timeline file (SCF) generated using predicted/restituted/TLE orbit files
- ANR-465: Start/stop UTC Dates not correctly checked under certain circumstances
- ANR-484: Mission file update mechanism not working

Version 1.6.1 of the DFDL4S Java and C++ Libraries has been released and can be downloaded here.
DFDL4S is a generic binary data binding library written in Java and based on the Data Format Description Language (DFDL). DFDL++ provides the same functionality exposing a native C++ API. See more details here.
The following is a summary of the changes in version 1.6.1.
New Functionality and Improvements
- Enabled support for repeating records based on occursCountKind=”expression”
- Added uniqueName()/absoluteUniqueName() that include record number in element name
- Enabled setting integer value in element with xs:hexBinary type
- Improved serialization of large packets built from scratch
- Reduce the dependency from 3rd party libraries
Bug Fixes
- Corrected the packet number passed to progress monitor

Version 2.6.4 of ESOVNG (Swath and Orbit Visualisation tool) has been released and can be downloaded here.
Release Notes are available here.
User registration is required. Please find detailed instructions here.

New Features
- Consolidation of instrument panel (remove ‘Apply’ button)
- Reviewed behaviour of ‘Apply’ button in Orbit and Map panels (‘Apply’ button disabled until a parameter in the panels has been edited)
- Support for Orbit Files compliant with version 3 of File Format Standard (FFS)
- Added at start-up a pop-up window to check for for availability of updated missions files
- Extended mechanism to check for updated mission files to detect new missions
- Allow multiple selection in Zones / Stations panels to remove zones/stations from list added to scenario
Corrections
- ANR-459: Logical operations: Return a message when the resulting number of segments is zero to inform the user that no time segments have been found as result of the logical operation
- ANR-467: Inconsistencies in Map Legend Settings
- ANR-469: Command Line Interface sometimes raises exception while the execution of the same Esov scenario file is successful from desktop application
- ANR-487: Internal Improvements regarding POF/ROF file type detection (use xo_orbit_get_mode) and retrieval of file validity for POF/ROF with GEO_MEAN_2000 frame (e.g Aeolus)
- ANR-491: Station copy mechanism does not work as expected
- ANR-494: Sort list with mission names when creating new scenario
Updated Mission Files
- Up-to-date orbit and instrument swath files
Version 1.4.0.6 of SAMIEdit (SAtellite MIssions 3D visualisation application) has been released and can be downloaded here.
Release Notes are available here.
User registration is required. Please find detailed instructions here.
New Features
- It is possible to import ESOV NG mission timelines file (.SCF) to generate time blocks, e.g to display dynamically instrument swath planning segments
- The display of Nadir direction can be enabled / disabled through the camera menu
- AzEl2LonLat plugin’s code that computes the ground stations mask radius has been updated to support MEO satellites (e.g. GPS, Galileo)
- Implementation of version checking with automatic update mechanism (Application —> Check for updates) for application , satellite models and mission files
- Up-to-date mission configuration files and example projects
Bug Fixes
- Cannot select Earth texture when adding time blocks to the timeline
- Cannot select orbit/attitude files if only one file in folder
- Orbit or attitude files that cannot be found during project load prevent the satellites and scenario to be created
