2. ADS-B State Vector Report Message: Type 0x91
The ADS-B State Vector Report Message is one of several message types sent by the MXS to report data on a particular
ADS-B In participant. The ADS-B State Vector Report Message contains information about a specific ADS-B participant.
This message is sent for aircraft/vehicles that are transmitting ADS-B information, within range as specified in the
Target Request Message (type 0x0B).
It provides position, velocity, and other information about an ADS-B participant.
The length of the ADS-B State Vector Report Message depends on the amount of information the MXS has received
from an ADS-B participant.
Since each report can contain at most, 85 targets, multiple reports may be transmitted for a single request.
An overview of the ADS-B State Vector Report Message is shown in Table 0-45Table 6-49
