During this operation the existing Ku-band radar and its antenna were replace with a modern X-band radar, after 18 years of loyal service. Setting the new radar to work is expected to take another two or three weeks. Air traffic continues without interruption because it is monitored by a different system monitors.

With this operation, LVNL clearly shows that they are investing in the continuity of efficient and, above all, safe handling of the busy air traffic.

The original plan was to replace the radar on September 13. However, the weather did not allow this. In order to work safely, no rain was allowed and the wind force had to stay below 4 Beaufort. A week later the weather was much more favourable, and the final go ahead was given the day before.

Once the operation started, progress was closely monitored. Everything was planned to 15 minute intervals. Just setting up the crane – which had to be absolutely level – took five hours. Also, the busy car traffic in the neighbourhood had to be rerouted because of the necessary closures.

HITT paid much attention to the preparations. "It is a challenging job, especially since we are upgrading a system in full operation." says project manager Huib Harwig, "In particular the co-ordination between Air traffic Control, airport Schiphol, suppliers of radar and radome, the concrete drilling company and the crane company were important to ensure a smooth operation".

With the replacement of the radar, LVNL has taken an important next step in the continuous modernisation of air traffic control at Schiphol airport.
