SATSOFT is used for assessment of antenna coverage and gain, development of contoured beam and multi-beam antenna designs, and many other tasks required for payload design and regulatory filings.
Pattern visualisation and coverage polygons
SATSOFT is designed for communication satellite antenna design, analysis and coverage planning. Supplier-furnished antenna patterns can be imported and managed with the Pattern Data Manager and subsequently inspected and visualised on a world map, while coverage polygons can be defined and displayed on the map. The SATSOFT Professional version gives advanced features such as accounting for pointing error and edge of coverage contours.
Postprocessing with Performance Tables and Delta Pattern
Imported pattern data as well as patterns generated with the built-in antenna models can be inspected and post-processed in several ways in SATSOFT. Cities selected from the supplied city database can be added to the map, including pointing error (SATSOFT Professional), and a Performance Table can be generated to tabulate directivity, EIRP, min/max as a function of pointing, among others. Similarly, all antenna patterns can be compared directly by generating their difference in dB using the Delta Pattern feature (SATSOFT Professional).
Synthesise contoured beam and multi-feed antennas
Users can synthesise antenna beams and designs using different antenna models, depending on the optional add-on modules for SATSOFT. The fast mini-max optimiser in SATSOFT quickly converges from an initial starting point to an optimum solution allowing you to evaluate the performance in detail.
Exchange data and designs with other TICRA programs
SATSOFT seamlessly interfaces with other TICRA programs. Pattern grids computed from detailed antenna analyses in TICRA Tools (GRASP, POS, QUPES, ESTEAM and CHAMP 3D) can readily be imported into SATSOFT. Similarly, multi-feed and shaped reflector antenna designs and coverages set up in SATSOFT (Physical Optics Reflector add-on module) can be exported to complete and ready-to-run POS and GRASP projects. This considerably speeds up the design workflow..
Pattern contour and polygon export
Pattern contours and polygons can be exported from SATSOFT in numerous formats. Displayed pattern contours can be exported to ITU GXT format, while they can also be exported in KML format for display in Google Earth with its vast rendering capabilities. Similarly, coverage polygons can be exported for use in other SATSOFT projects, with POS and with STK, among others.
