EUROCONTROL - Provision of technical support for the RVSM Height Monitoring System TMU software


The European Regional Monitoring Agency (RMA) is responsible for the technical oversight of aircraft altimetry system performance in the European Reduced Vertical Separation Minima airspace (RVSM). The major activity in respect of this specification is monitoring aircraft height keeping performance, and taking appropriate action when altimetry system performance thresholds are exceeded.

To date, the technical height monitoring infrastructure consists of 3 EUROCONTROL Height Monitoring Units (HMU) in Europe (Equipment located in 5 countries). These provide the bulk of the data for height-keeping performance and technical risk analysis. The central data processing system within the HMU, the Total Vertical Error Monitoring Unit (TMU) processes input plot data to estimate the accuracy of the aircraft altimetry system by comparing the geometric height of the aircraft against the predicted geometric height of the pressure level equal to the assigned flight level of the aircraft. The output of the TMU system is a list of aircraft height-keeping performance results for all aircraft meeting minimum track criteria, and operating within the coverage of the HMU system. A critical parameter within these results is the estimation of the aircraft’s Altimetry System Error (ASE).

The TMU is a unique software system requiring a range of subject proficiencies to maintain and develop. These include geopotential altitude modeling, aircraft tracking algorithms, digital signal processing, data smoothing, and real-time data processing.

The EUR RMA has conducted feasibility studies to estimate aircraft ASE using aircraft ADS-B transmissions through a modified TMU.

The scope of this 5 years contract is to provide technical support for the TMU software. Principally this will be to further optimize the TMU software for enhanced processing of ADS-B data for height monitoring purposes and to integrate this software within the EUROCONTROL NM SIAAAM Data Collection, Management and Analysis platform (SDCMA). The SDCMA is a platform that will provide support to the EUROCONTROL NM function to comply with the Implementation Rule IR (EU) 2019/123.
