8.4.9 TIS‐BReportMessageOverview

LikeADS‐BInReports,TIS‐BInReportsaresentwhenpositiondatabecomesavailableforaTIS‐Bparticipant

andthereafterasparticipantdatachanges.IfthepositiondataforaTIS‐Bparticipanthasnotbeenupdatedin

120seconds,TIS‐BInReportsarenolongersent

forthatparticipant.

TwotypesoftargetsaredefinedforTIS‐B:FineTargetsandCoarseTargets.

ThedataavailableforFinetargetsissimilartothedataforADS‐BtargetsandisreportedinTIS‐BStateVector,

ModeStatusandAir ReferencedVelocity(ARV)Reports.Thesemessages

arebasedontheirADS‐Bequivalents

butwithafewmodificationstosupportTIS‐B‐specificdata.

ThedataforcoarsetargetsiscombinedintoasingleCoarsePositionReport,containingallthedataavailable

fortheCoarseTIS‐Bparticipant.
