Antenna Pattern Synthesis Software

The antenna pattern synthesis software, specially developed in-house by TechCom engineers, is an efficient tool for the design and specification of spacecraft antenna patterns.

The software improves the capabilities of satellite operators in the following areas:

• Early optimization of spacecraft coverage based on commercial service requirements
• Early assessment of mission feasibility with demanding coverage requirements (EIRP, G/T, isolation)
• Focusing the set of spacecraft requirements towards the manufacturer, supporting sizing (mass, power, capacity, fairing constraints) for new programs
• Accurate recreation of steered beam patterns (for coverage prediction or spectrum coordination purposes)
• IOT preparation and analysis
  • Predict generation for payload IOT antenna mapping
  • Pointing bias estimation and sensitivity analysis
  • FMS-data evaluation and location optimization
  • Thermo-elastic effects analysis

Main features:

• Multiple configurations support:
  • Single or dual-shaped reflector geometries
  • Multi-feed arrays, including combinations with shaped reflectors (hybrid antennas)
  • Single or multiple beam configurations
• Optimization with various degrees of freedom:
  • Shaping of main and/or sub-reflectors
  • Feed excitation coefficients optimization (or selectable subset), feed coordinate system, individual feed positions (theta, phi, z-coordinate) for minimum scan-loss
  • Convergence tracing through interim viewing of results (between iterations of residuals and optimizing for number of feeds, reducing sidelobes)
