Satellite | ATDI


Radio is essential in exploring the solar system. 

Earth-satellite communications facilitate everything from GPS to television broadcasts.

Satellites can provide broadband when no other signals exist.


ATDI is expert in assessing signals travelling to and from our planet. While ATDI has worked with satellites in Earth orbit, its scope goes far beyond this. ATDI was intimately involved in communications for the missions to Mars being mounted by the French space agency, Cnes.  ATDI’s HTZ warfare planning and modelling software was central in assessing communications between Earth and all Cnes space vehicles.

ICS telecom EV features advanced satellite network planning functions for GSO/non-GSO satellite operators, system integrators and service providers. Features include:

  • GSO/non-GSO satellite coverage planning and link budgets
    (EIRP, G/T, C/N)
  • Wide-beam and HTS beam planning across all satellite
    frequency bands
  • Automated site planning, frequency planning and site optimisation
  • GSO vs GSO and GSO vs non-GSO interference analysis
    (ΔT/T, C/I, PFD and EPFD masks)
  • Satellite vs terrestrial co-existence analysis
  • Earth station coordination (ITU APP 7)
  • DTH network planning
  • VSAT network planning and optimisation
  • Covers all satellite services: FSS, BSS, MSS, Earth-exploration, meteorological and more

HTZ warfare, ATDI’s military radio planning tool, features a host of additional features for military network operators facing challenges such as network planning on a dedicated government satellite or optimising military traffic on a commercially leased capacity. Features include:

  • COTM (Communications on The Move) network planning for tactical forces
  • In-band and out-of-band interference analysis
  • Supports high resolution digital cartographic maps
  • Planning of airborne government missions
  • Transponder gain settings.

Case: Effective VSAT network design


Whether the industry is banking, retail, energy or mining,  companies rely on a dependable corporate communications network which is critical to running a smooth operations. The dynamic changes in applications and the size of networks, as well as the use of numerous resources such as multiple satellites at different orbital locations and different Earth station equipment manufacturers, can present significant technical challenges. Using an efficient planning process is crucial to providing a high-quality user experience and ensuring reduced infrastructure costs.


Using the capacity planning functions in ICS telecom EV, a satellite engineer can design a compliant network ensuring each site’s specific technical parameters and usage patterns are applied and guaranteeing that every user is provided with the required quality of service. ICS telecom EV features advanced database management capabilities for both satellites and earth stations. These functions provide a reliable, up-to-date status of network resources in use and support on-going optimisation of the network’s application of spectrum and infrastructure at every stage of network development.


Case: Growth of spectrum usage in the satellite frequency bands


Over the past few years, there has been explosive growth in demand for spectrum in the frequency bands allocated to satellite services across the globe. This is due, in part, to the increasing range of uses and applications consuming satellite bandwidth. Added to that, recent decisions by the WRC (World Radiocommunication Conference) to allocate new services, such as terrestrial mobile, in the same bands has added to the burden on the satellite service providers who must ensure interference-free operations and guaranteed quality of service to the end user.


The analysis of neighbouring operating satellite networks is no longer sufficient to understand spectrum occupancy and the impact of potential interference levels across the operating frequency bands in the network. ICS telecom EV features dedicated planning functions across all radiocommunication technologies (mobile, broadcast, PMR, radar and more), and offers a wide range of terrestrial and satellite propagation models (ITU-R P.526, P.618, etc) and antenna pattern library (ITU-R S.580, S.465, etc).

ICS telecom EV users benefit from these multi-technology features which enable them to perform accurate analysis of aggregate interference stemming from various sources such as mobile 4G vs satellite ES, fixed MW stations vs FSS, BSS feeder links vs FSS receiving ES and more.
