Becker Avionics Receives Order from FAA

Becker Avionics has announced that it has received an order from the Federal Aviation Administration (FAA) for three ICAO Ground Based Augmentation Systems (GBAS). The systems will be delivered to the FAA within the next 2 months.

The FAA GBAS systems are intended to support:
• All types of aircraft approaches (precision, non-precision, and missed)
• Landing function that offers an alternative precision approach system to ILS (Instrument Landing System) or MLS (Microwave Landing System)
• Departures
• Surface operations
Additionally, with the same performance, the GBAS systems may also support additional operations:
• En-route operations
• Terminal operations

About Becker Avionics GBAS System

The RS4909A/RE9009A is a VHF Data Broadcast (VDB) receiver designed for GBAS/LAAS CAT I data reception requirements for ground stations. The system is comprised of the integrity receiver of the VDB unit for the GBAS Ground Subsystem, included in the Global Navigation Satellite System (GNSS). The VHF Data Broadcast receiver TS4909A/RE9009A has been developed for VDB monitoring in the range of 108.025-117.950 MHz. Due toits modular design concept, unit maintenance is easy and quick with a simple replacement system for a defective sub-assembly.

The VHF Data Broadcast GBAS/LAAS (VDB) Receiver characteristics are:
• Frequency range:  VHF NAV band (108.025 – 117.950 MHz)
• Channel spacing: 25 kHz.
• Operating mode: VDB for GBAS Cat 1
• Modulation: D8PSK (Differential 8 States Phase Shift Keying).
• Frequency stability: ≤ 1ppm (-20°C to +55°C).
• Remote and local operation

• Integrated remote control and remote processing (RS485, protocol J-BUS)
• Digital processing of the signal (DSP)
• Configurable in local from ASCII/PC, or by remote with a PC
• Built-in-test feature
• Automatic switchover from AC to DC in case of main voltage shutdown
