Overview

The BXP641X is a functional combination of Mode A/C/S transponder, ADS-B subsystems with cost efficient SBAS GPS receiver and barometric altimeter integrated in one device.
The space-saving device is also designed for remote operation and can be controlled via a control panel or a glass cockpit.

Features

ModeS Transponder:

  • The BXP641X includes fully functional Class 1 (250 Watt), Level 2 Datalink ModeS, ELS transponder.
  • The ModeS functionality complies with the current worldwide requirements ETSO-C112e. Compliance with ELS and Extended Squitter is shown at the installation level per CS-STAN and EASA CS-ACNS.
  • The transponder operates with a single antenna.

ADS-B Out Compliant:

  • The BXP641X includes a 1090 Mhz airborne ADS-B system that provides transmission functionality of a Class B1S device.
  • The transmitting subsystem broadcasts aircraft identification, position, velocity and status data.
  • With a external certified GPS receiver, the BXP641X meets all European and US requirements for ADS-B mandate.

Barometric Altimeter:

  • A built-in temperature controlled barometric altimeter acts as the precision source for flight levels up to 35,000 ft.
  • Rigor certification according to ETSO-C10b allows using the BXP641X as a primary source for barometric altitude in aircraft which can be easily connected to the FMS, GPS, or Terrain Awareness System.
  • The barometric altimeter allows quick changes of reference pressure.

SBAS GPS Receiver:

  • The BXP641X includes a GNSS receiver that complies with the EASA ETSO-C199 spec. Such GPS receivers are the perfect compromise between price and accuracy for light helicopter and aircraft.
