Avinor AS Oslo Airport Gardermoen opened in 1998 with one weather radar. This is an S-band radar and was delivered by Alenia/Selex together with a primary and secondary radar. This radar will be replaced with a new primary and secondary radar in 2020. Without a weather channel. Avinor will separate these two systems. We have now a mobile weather radar from Selex- Gematronik hired in from Met Norway in operational use. The intention of this contract is to replace the mobile weather radar.
