Continued investment and development of solutions to support challenges in the satellite sector

Satellites provide vital communications to any part of the World. However, the technology is associated with problems that can be mitigated through network planning and modelling techniques.

Propagation delays from one VSAT to another can exceed 0.5 seconds, impairing voice communications and resulting in echo and talker overlap. These delays can be resolved by applying unique protocols. Satellites are also susceptible to rain and atmospheric disturbances, commonly known as noise. To support this, ATDI’s software features rain maps and other significant atmospheric data to support network planning.

HTZ is a comprehensive radio network planning tool that enables network operators to plan and model the satellite footprint. It also models and manages constellation interference and evaluates interference between the satellite and earth stations.  

HTZ features advanced satellite network planning functions for GSO/non-GSO satellite operators, including:

  • GSO/non-GSO satellite coverage planning and link budgets
  • Wide-beam and HTS-beam planning across all satellite frequency bands
  • Connection and import of ITU SRS database and TLE files
  • Automated site planning, optimisation and frequency planning
  • GSO vs GSO and GSO vs non-GSO interference analysis
  • Satellite vs terrestrial co-existence analysis
  • Earth station coordination
  • DTH network planning
  • VSAT network planning and optimization
  • Covers all satellite services: FSS, BSS, MSS, Earth-exploration and meteorological

This tutorial looks at satellite coordination between earth stations and fixed services.
