White Paper on E2E mission performance simulation chains
White Paper on E2E mission performance simulation chains (v1.2) has been updated and can be downloaded here.
This white paper captures lessons learned in the procurement and technical development of End-to-End mission performance simulation chains for Earth Observation. These tool chains includes simulation of both the target scene and the space segment, as well as the Level 1 and Level 2 processing.
The document provides recommendations, templates and reference to tools implementing common practices addressing the lessons learned.
New Release Announcement - SNEAK v1.5.0
Version 1.5.0 of SNEAK has been released and can be downloaded here.
The inStrumeNt sourcE pAcket toolKit (SNEAK) is composed of a set of command line utilities to extract/manipulate the values of specific ISP fields in L0 RAW file.
Documentation for can be found here.
The following is a summary of the changes in version 1.5.0.
New Functionality and Improvements
- Added isp_annotate to prepend an annotation to all ISPs in a given file
- Update isp_transform to allow applying the transformation only to ISPs where some field has value in a given range
- Added isp_crcfix to correct the CRC of the ISP (this was already included in 1.4.0)
- Enabled isp_sequencer to consider a single counter shared by multiple ISPs (this was already included in 1.4.0)
- updated the FLEX schema example to include the latest schema (v1.0.3)
- Built using DFDL4S v2.0.0, so it requires Java 11 (also compatible with the latest Java 17 LTS release)
E2E Performance Simulator Generic Requirements Template v2.0 issued
Version 2.0 of the "Generic E2E Performance Simulator and L1PP/L2PP Requirement Document " has been published and can be downloaded from here.
