M10AL is the latest generation ADS-B station designed and manufactured by NRPL under ISO 9001:2008 certified quality system.

The system complies with all ICAO requirements and it has been designed using the latest, best-known technological improvements. The system is highly modular and can be either fully redundant with automatic switch-over or single- channel for N-1 architecture.

M10AL can be used either separately or as a complement to existing PSR/MSSR radars while using only one data processing center. Several stations can be easily extended to MLAT network (airport or WAM).

Antenna System

  • Variable number of input antenna channels (1 – 4)
  • M10AL can be used with several antenna types depending on required coverage:
  • Three 120° degree 17 dBi gain sector antennas
  • One omni-directional 11.5 dBi antenna
  • One omni-directional 9 dBi antenna
  • One omni-directional 5 dBi antenna

Data Processing

  • Mode A/C, Mode S ES, Mode S ELS/EHS processing and 3D position calculation

  • Any number of local and remote CMS terminals
  • Highly adaptable to local communication lines such as serial, optic, LAN, radio link etc.
  • Non-radar equipment control can be easily imple- mented in CMS displaying all available data
  • Real-time performance calculation
  • Information archiving, replay and analysis
  • SNMP support
  • Factory remote support capability

Radar Data Display

  • Multiple data (plots and/or tracks) input display including PSR, MSSR, ADS-B and MLAT
  • Geographical maps and air navigation charts
  • Surveillance data archiving and replay

MLAT System Features

  • Consists of several M10AL stations and one or several interrogators
  • M10AL can be either redundant or single-channel providing extra degree of reliability
  • Using Mode A/C, Mode S ES, Mode S ELS/EHS for interrogation
  • Can be used either separately or as a complement to existing PSR/MSSR radars while using only one data processing system
  • Enhanced coverage calculation
  • Redundant central data processing system
