9. ADS-B In Report Message Overview
Extended Squitters messages received by the MXS report Position, Velocity, Identification and Category, Target State and
Status, and Aircraft Operational Status. From this data, MXS generates ADS-B, TIS-B and ADS-R reports for delivery to
the flight computer which communicates the data to the user.
ADS-B In Reports are sent when target position data becomes available and thereafter as participant data changes. If the
data for a given ADS-B In participant
12
has not been updated for a specified amount of time ADS-B In reports are no
longer sent for that participant.
If enabled in the Target Request Message, the MXS sends out ADS-B In Report Messages for the host aircraft’s position.
The Host controls the number of targets reported on and the types of reports sent for those targets and requests a report for
a particular target using the Target Request Message.
