La fourniture de services de données à haut débit nécessite l’utilisation de dizaines ou de centaines de stations sol. La mise en œuvre efficiente d’un si grand nombre de stations sol soulève de multiples questions de conception, notamment : –

  • Combien de stations sol sont nécessaires ?
  • Combien de stations sol de diversité ?
  • Où implanter les stations sol pour la meilleure disponibilité ?
  • Quel est le gain optimal pour chaque antenne ?
  • Quel est le bilan de liaison/marge de sensibilité optimal ?
  • Comment gérons-nous et exploitons-nous les stations sol ?
  • Puis-je prendre en charge plusieurs services ?

The Design Tool applies the Atheras proprietary Outage Prediction Algorithm (OPA) to historic rainfall measurements for specific gateway locations to determine the historic satellite link availability for those locations.  Applying the OPA to multiple gateway locations across a region permits a satellite operator to (i) analyse each candidate gateway site for historic link availability,  (ii) determine weather correlations between individual candidate sites and (iii) determine overall network availability for specific groups of gateway locations.

Applying this process in an iterative manner to different groupings of gateway locations enables a satellite operator to optimise the design of a network for maximum overall network availability based on selecting  (i) gateways with the “best” historic link availability and (ii) groupings of gateways with the maximum weather independence between gateway locations to minimise the number of sites affected by the same weather system at the same time.

The Design Tool will hence enable satellite operators to optimise the selection of gateways for their next-generation, multi-gateway satellite networks to provide the most cost-effective network configuration
