TIS-B, kapena Mauthenga a Zamtundu wa Zamtunda-Broadcast, ndi ntchito yofalitsa deta yomwe imalola operekera ndege kuti adzalandire chidziwitso cha magalimoto pafupi-nthawi yeniyeni. Pakati pa FIS-B, TIS-B ikuperekedwa popanda ogwira ntchito kwa abasebenzisi a ADS-B monga gawo la FAA's Next Generation Air Transportation System (NextGen) .
TIS-B ndi njira yofotokozera zamagalimoto yomwe imagwiritsa ntchito malo osungirako zinthu ADS-B ndi dera la radar kuti lidziwe deta ya ndege pa mawonedwe a ndege.
Kwenikweni, TIS-B idzawathandiza oyendetsa ndege kubwalo kuti aone zomwe woyendetsa galimotoyo akuwona - ndege zina, pamodzi ndi maulendo a ndege, maulendo, ndi zothamanga zowonetsera pazenera zawo.
Momwe TIS-B imagwirira ntchito
Dongosolo la TIS-B limaperekedwa kuchokera ku malo osungirako ndege mpaka ndege zonse za ADS-B , kaya ndege ikugwiritsa ntchito chiyanjano cha 1090 MHz ES kapena chiyanjano cha data cha 978 MHz UAT. Mauthenga apamtunda amatengedwa kuchokera ku radar sensors pa malo osungirako malo ndi mauthenga kudzera ku ADS-B maulumikizidwe a ndege.
Wopereka ADS-B wa ndegeyo adzamasulira deta ndi kuwonetsera izo pazenera pa chipinda. Maonekedwe enieni omwe TIS-B adzawonetsedwe adzasintha ndi mitundu yosiyanasiyana ya avionics pamsika lero, koma mosakayikira adzaphatikizidwa mu kayendedwe ka ndege kapena fulampu yothamanga (EFB) ku dipatimenti ina. Kawirikawiri, magalimoto amawonetsedwa ngati katatu kakang'ono ndi mzere wowonetsa kayendetsedwe ka ndege ndi liwiro, ndi kuwerenga kwapamwamba kwinakwake pafupi ndi chizindikiro cha katatu cha ndege.
Zida
Ophunzira oyendetsa ndege omwe akufuna kulandira mauthenga a TIS-B pa ndege awo ayenera kukhala ndi ojambula ADS-B ovomerezeka ( ADS-B Out ) ndi ovomereza (ADS-B In), kapena transceiver (onse). ADS-B imafuna WAAS -wolandira GPS wolandila ndi transponder pamene wina alibe kale ndi gawo la ASD-B.
Kuwonetsera kanyumba kovomerezeka (CDIT) kumafunikanso kusonyeza magalimoto mu mawonekedwe ojambula.
Zolepheretsa
Pali zochepa zochepa zomwe zilipo ndi TIS-B kuti oyendetsa ndege ayenera kudziwa pamene akuuluka:
- TIS-B ndi chidziwitso mwachilengedwe
- TIS-B imapezeka pokhapokha m'madera omwe amathandizidwa ndi TIS-B komanso pamene pali gawo limodzi la ATC radar unit.
- Radar imatsalira pambuyo pa ADS-B pokhudzana ndi zosintha. Kuyambira pamene ADS-B ikuwongolera pafupi kamodzi pamphindi ndi radar ikukonzanso masentimita atatu kapena 13, ndizotheka kuti oyendetsa ndege angayang'ane cholinga cha ndege yawo pamene akuyenda patsogolo pa ATC akudziŵa zolinga zomwezo.
- TIS-B imagwiritsira ntchito data ADS-B ndi data radar. Nthawi zina, mauthenga omwe adalandira kuchokera ku ADS-B ndi radar akhoza kukhala osiyana kwambiri ndi wina ndi mzake ndipo amatanthauziridwa molakwika. Izi zingabweretse ziwerengero zowerengera zamagalimoto pamasewero.
- Ndege iyenera kukhala yokhala ndi transponder yogwira ntchito kuti iwoneke ngati cholinga pawonetsera.
FAA imachenjeza oyendetsa ndege kuti TIS-B sichimalowetsanso njira yolekanitsa magalimoto ndi njira zopewera. Mosiyana ndi TCAS, TIS-B samapereka malangizo othandizana ndi magalimoto komanso kuyendetsa magalimoto sikuvomerezedwa. Oyendetsa galimoto ayenera kukumbukira kuti kuyendetsa pamsewu sikuvomerezedwa poyang'ana mawonetsero a TIS-B, ndipo kuphulika kwa ATC kungakhalepo ngati woyendetsa ndege achoka pamalangizo ake.
