The PRISMA product family offers a full range of air traffic management (ATM) modules designed to support the most varied use-case scenarios, ranging from standalone solutions to integrated surveillance and flight plan data processing systems.

PRISMA’s fully expandable and modular architecture enables the continuous addition of functionality, supporting a buy-as-you-grow approach. Based on our extensive experience in advanced air traffic automation systems, PRISMA can be easily integrated with 3rd-party components.

PRISMA can vertically integrate information along the complete surveillance data chain, from multiple sensor sources to leading European trackers such as ARTAS or multi-sensor data fusion systems. By presenting different views of all this data, PRISMA supports seamless situational awareness during all phases of flight.

PRISMA’s ATM automation modules are designed by air traffic controllers, for air traffic controllers - and their ongoing development is driven by senior ATC operational experts. The system design is based on industry best practices and is compliant with ICAO, Eurocontrol and EUROCAE standards. Ongoing development is aligned with the ICAO’s global air navigation plan (ASBU roadmap) and the SESAR deployment programme. 

Ensuring uninterrupted operations is vital within the ATM sector. Air Navigation Service Providers must be equipped to handle a wide range of potential disruptions, including cyber attacks, natural calamities, and system malfunctions. Frequentis' PRISMA offers a reliable and independently developed solution, providing an easily implementable backup for primary automation systems from companies such as Thales and INDRA.

The PRISMA flight data processing system (PRISMA-FDPS) module supports the automated processing of flight plan data and surveillance data for air traffic services. FDPS offers the option to forecast traffic levels, calculate estimated times of operations, and validate distances between targets. It also supports free route operations thanks to its very accurate 4D predictions of flight trajectories.

PRISMA-FDPS promotes easy collaboration through the notion of flight objects: after the creation of an SFPL, all metadata resulting from system or user interactions with that SFPL is added to a database accessible to all client systems, ensuring the availability of the most up-to-date and comprehensive information. The system provides an intuitive graphical user interface for accessing and managing SFPLs, and its silent coordination feature via ground-ground data link enables a smart handover process.

PRISMA-SNET is a SWAL-3, fully redundant backend module for calculating alerts related to flight safety. The module receives ATS surveillance reports in ASTERIX format and flight plan information from the corresponding FDPS service. Calculated alerts are based not only on surveillance and flight plan information but also on meteorological parameters such as atmospheric pressure and temperature. This improves alert filtering and avoids the nuisance of false alerts.

Generated alerts are transmitted to the systems using EUROCONTROL ASTERIX CAT004. PRISMA-SNET supports multi-hypothesis trajectory prediction to improve warning times. PRISMA-SNET can be configured and tuned to support multiple horizontal separation applications within the domain of interest. In addition, the system makes use of the downloaded aircraft parameters to exploit every piece of information that can be obtained from modern surveillance systems.

Optimised situational awareness through seamless integration

In their everyday work, air traffic controllers must often simultaneously use multiple systems from different vendors to access the information and controls they need. This can be extremely frustrating and time-consuming, especially at times of high traffic load when operator stress levels are already considerably higher.

To address this inefficiency, PRISMA features a workflow-oriented controller working position that combines all essential information into one interface for enhanced situational awareness and faster reaction times. PRISMA’s controller working position (CWP) is a SWAL-3, high-performance, flexible and fully configurable HMI offering the integrated presentation of all surveillance data (radar, ADS-B and multilateration), for seamless air-ground situational awareness on a single screen. PRISMA CWP, in combination with other Frequentis ATM modules, creates a fully integrated surveillance data processing system.

Air situation display

The air situation display (PRISMA-ASD) is a cost-efficient and service-oriented awareness display system featuring one main traffic window including weather information, enabling controllers to stay focused on the traffic in the assigned area. Additional support windows provide workflow-oriented information, to significantly reduce controller workload.
