PURPOSE

MAS 2700 is the state-of-the-art scalable, modular solution for providing aeronautical surveillance using multilateration (MLAT) and automatic dependent surveillance - broadcast (ADS-B) technologies. MAS 2700 detects and tracks aircrafts (ACs) and other targets equipped with Mode A/C/S transponders, as well as with ADS-B 1090ES (extended squitter) transmitters. Due to modular architecture MAS 2700 could be adapted/extended to fulfill different surveillance applications, either separately or in conjunction

• Surveillance of ACs and vehicles on the aerodrome surface (A-MLAT);
• Surveillance of ACs in the final approach phase (PRM approach);
• Surveillance of ACs in the terminal area and/or en-route airspace (WAM);
• Providing information contained in the extended squitters transmitted by ACs and/or vehicles equipped with ADS-B 1090ES transmitters;
• Extraction of on-board aircraft systems parameters using the ground-initiated Comm-B (GICB) protocol;
• The passive surveillance feature;
• Monitoring of the information integrity transmitted in the extended squitters of ACs and/or vehicles equipped with ADS-B 1090ES transmitters;
• Height-monitoring unit (HMU).

MAS 2700 fully meets the requirements of EUROCAE documents ED-117A, ED-142, ED-129B. Ready to provide Composite surveillance functionality (ADS-B and WAM) in line with future ED-142A. The first product certified in the Russian Federation that provides the functions of the ADS-B system in accordance with the requirements of EUROCAE ED-129B.

COMPOSITION AND FEATURES

Ground receiving stations:

• High reliability (MTBF, MTTR);
• Receiver with three independent receiving channels and sector (120⁰) antennas provide high spatial selectivity of signals and the ability to detect spoofing;
• Unique proprietary algorithms for decoding RF signals provide high efficiency of detecting useful signals in the presence of synchronous and non-synchronous interference and high accuracy of signal timestamp.

Central processing unit:

• Best performance in the market (up to 400 ground stations can be connected and up to 1024 targets can be processed simultaneously);
• Hot redundancy concept;
• MLAT/ADS-B composite surveillance functionality in line with future ED-142A;
• ADS-B data validation using multilateration (2D/3D) and direction finding of signals;
• Standard ASTERIX output (any other protocol is appropriate at the customer request);
• Multiple data output (8 or more directions) with individually configurable parameters;
• Three data output modes to ensure compatibility with any type of surveillance data processing and display systems:
  • "Data driven mode": is appropriate for surveillance processing systems capable of handling high data rates and non-periodic update;
  • "Periodic mode": is for legacy surveillance processing systems that can process data with a constant update period ("quasi-radar" mode);
  • "Periodic predicted mode" ("tracker" mode): is intended to provide a suitable input for a direct controller plot display (system without an surveillance data processing tracking system of its own).

Control and monitoring terminal:

• real-time comprehensive monitoring of the status and parameters of system components;
• failure identification and isolation at the standard line replaceable units (LRU) level;
• user friendly interface;
• remote control and monitoring of operation of the system and its components;
• recording of all incoming and outputting information, data logging for a period of minimum 1 month, as well as extensive options of playback;
• convenient application for display of the current air situation and system performance (MLAT / ADS-B tracks/plots with extensive options for configuring display labels), the function of superimposing aeronautical and cartographic information, changing the display scale.
