Abstract:
Ukulandelela i-GPS sekusetshenziswe kakhulu ezifundweni zezilwane zasendle emashumini eminyaka amuva nje, kodwa ukusebenza kwakho akuzange kuhlolwe ngokugcwele, ikakhulukazi kuma-transmitters asanda kwakhiwa. Sihlole ukusebenza kwezithutha ze-GPS eziyisishiyagalombili ezithuthukiswe e-China ngokuzinamathisela ku-Crested Ibises Nipponia nippon evalelwe kumakheji okujwayelana alingisa izindawo zokuhlala zangempela. Sibale ibanga phakathi kwezindawo ze-GPS kanye ne-centroid yamakheji njengephutha lokuma, futhi sasebenzisa amaphutha okubeka angu-95% (95th percentile) ukuze sichaze ukunemba. Impumelelo yokubeka ifinyelele ku-92.0%, ephakeme kakhulu kunaleyo yezifundo zangaphambilini. Izindawo azizange zisatshalaliswe ngokulinganayo Ikilasi Lendawo (LC), kanti izindawo ze-LC A no-B zibalelwa ku-88.7%. Iphutha lokuma elingu-95% eliphawuliwe ezindaweni ze-LC A (9–39 m) kanye no-B (11–41 m) lalinembile impela, kuyilapho kufikela ku-6.9–8.8% wezindawo zekhwalithi ephansi zitholwe ku-LC C no-D ngephutha lokuma>> 100 m noma ngisho>> 1,000 m. Ukubeka impumelelo nokunemba bekuhlukile phakathi kwezindawo zokuhlola, mhlawumbe ngenxa yomehluko wesakhiwo sezitshalo. Ngakho-ke, siphikisa ngokuthi ama-transmitters ahloliwe angahlinzeka ngenani elikhulu ledatha yekhwalithi ephezulu yezifundo ezisezingeni eliphezulu, kanye nenani lezindawo ezisezingeni eliphansi ezidinga ukunakwa. Siphakamisa ukuthi i-HPOD (ukuhlanjululwa okuvundlile kokunemba) noma i-PDOP (i-positional dilution of precision) kubikwe esikhundleni se-LC njengesilinganiso sokunemba kwendawo yendawo ngayinye ukuze kuqinisekiswe ukuhlonzwa nokuhlunga izindawo ezingenakwenzeka.
