• Transponders with ADS-B In are useful for sense and avoid applications by providing the user with
surrounding traffic information with a nominal range of 120 nautical miles (NM).
3.2.3 ADS-B Out
• Verified to meet the applicable requirements of DO-260B for a Class A2 ADS-B Transmitter.
• Provides Flight computer-controlled Automatic Dependent Surveillance-Broadcast Out (ADS-B)
capability.
• Transmits Extended Squitter (ES) and Acquisition Squitter messages at regular intervals, providing
Position, Velocity, Identification and Category, Emergency/Priority Status, Target State and Status,
Aircraft Operational Status, and other aircraft data. There is no way to disable Acquisition squitter
independently of the Mode S functionality
• Altitude data for the ES can be based on the MXS’s integrated altitude encoder, or one provided
external to the MXS.
• GPS data, also included in the ES, is provided to the MXS from an external source.
3.2.4 Altitude Encoder
• Verified to meet the applicable requirements of AS8003 for a Pressure Altitude Encoder.
• Computes own-ship barometric altitude with an integral pressure sensor and encoder.
• Calibrated up to 55,000ft. Can be calibrated up to 85,000ft upon request.
3.2.5 Attributes of the MXS transponder include the following
• GPS input is accepted from the Host Interface command link, or from NMEA or Accord GPS sensors
over serial communication ports.
• Supports antenna diversity (dual antennas located on the top and bottom of the aircraft).
• Supports aircraft system installations of one or two Transponder/ADS-B L-Band antennas
• Integrated pressure altitude sensor and encoder that provides required altitude data when the
static pressure port is connected to a static air pressure line.
• The MXS measures approximately 3.50in (89.0mm) x 2.09in (53.0mm) x 1.00in (25.4mm). (see
Section 5.1)
• Operating temperature is -40°C to +70°C
• Storage temperature is -55°C to +85°C.
• Nominal input supply voltage range is 14-28 VDC.
• Aircraft Flight computer communication is either RS-422, RS-232 or Ethernet using the Host
Interface protocol defined ICD02373
3.2.6 Control Interface
The MXS has a control and configuration serial interface that is used to configure the equipment at
installation time as well as command and control the device during operation. Typically, the MXS is
