Description
The Design Engineering Suite for Earth Observation (DESEO) is a software toolkit to support mission analysis and preliminary system/subsystem design activities for all phases of Earth observation missions.
DESEO has been designed to be used by mission and system engineers throughout all phases of an Earth Observation mission (from Phase 0 to Phase E), whenever they need accurate and fast quantitative results to support design trade-offs and assessment analyses.
DESEO is a modular, flexible and self-standing application, designed so as to provide the user with a comprehensive set of mission-related and system-related computation modules and with post-processing utilities to yield meaningful numerical and graphical results.
For the DESEO development, reliable and proven algorithms and routines have been used. Moreover, the need of flexibility and modularity drove the design toward an Object-Oriented (OO) architecture design. The OO architecture also reduces maintenance and upgrade costs.
The DESEO toolkit, besides the DEIMOS native algorithms, also integrates ESA EO CFIs libraries, providing additional means for performing embedded analyses.
DESEO has been designed in order to support system studies based on first-order estimation of spacecraft system/subsystems performance and mission analysis assessments, with powerful visualisation capabilities.
The tool is able to generate outputs for a specific set of inputs, and in certain cases it can also provide parametric results as a function of given variables (e.g. orbit altitude). The tool main objective is firstly to be an analysis tool (i.e. used to evaluate a given design). Nevertheless, some of its components have been developed for identifying an optimal design.
DESEO is currently composed of 38 modules (Analysis Processes) that can be used as stand-alone tools (command line) or operated via a Graphical User Interface (GUI). The Analysis Processes encompass orbit selection, orbit propagation, attitude computation, coverage analyses, timeliness analysis, ground station contact analyses, orbit maintenance, EOL analysis, OBDH analysis, delta-V budget assessment, power budget analysis and basic astrodynamics computations (geometric calculations, transformations, analytical formulas).
The GUI provides functionalities to manage the input insertion process (e.g. importing data from a database or from other input files), the analysis executions and monitoring (by means of log messages and progress bars) and the output visualisation. The GUI visualisation module is capable of producing 3D interactive visualisations, Gantt charts, Cartesian plots, cartographic map representations and tables.
The Analysis Processes are the core of DESEO, in charge of performing the Mission and System Analyses. The DESEO Analysis Processes have been developed in C++, while the GUI is implemented in Java based on the Eclipse RCP.
DESEO has been developed to run on Windows and Mac OS X Operating Systems.
