OneControl MLAT


Get end-to-end approach and on-ground surveillance at airports.

OneControl MLAT - ADB SAFEGATE's latest addition to its Tower ATM portfolio - is the answer to airports' growing needs for secondary ground surveillance especially during low visibility conditions. It helps streamline operations, minimize costs and most importantly improve safety.

The OneControl MLAT is the most accurate and high precision multilateration product available in the market. It is a critical component of ADB SAFEGATE's OneControl solution for airports and guarantees a full and easy integration with the Advanced Surface Movement and Guidance Control System (A-SMGCS). 

The key elements of OneControl MLAT are:

  • Remote unit (RU) equipped with receiver and transmitter
    The receiver of the RU receives, decodes and estimates the time-of-arrival (ToA) of secondary surveillance radar (SSR) signals. The transmitter is able to interrogate transponders and to transmit SSR signals. The RU can also be installed without transmitter and/or in redundant configuration.
  • Reference Position Validation
    The unit performs continuous system validation and system integrity checks so that the required accuracy can be guaranteed.
  • Central processing and control unit (CPCU)
    The CPCU is the central node of the multilateration system. All RU data is received and processed at the CPCU to generate the system output.
  • Data links between RUs and CPCU
