Isishwankathelo:
Ukulandelela i-GPS kuye kwasetyenziswa kakhulu kwizifundo zezilwanyana zasendle kwiminyaka yakutshanje, kodwa ukusebenza kwayo akuvavanywanga ngokupheleleyo, ngakumbi kwiitransmitter ezikhaphukhaphu ezisandula ukuphuhliswa. Sivavanye ukusebenza kweetransmitter ze-GPS ezisibhozo eziphuhliswe eTshayina ngokuzincamathisela kwiCrested Ibises Nipponia nippon ezivalelwe kwiikheyiji ezimbini zokuqhelana ezilinganisa iindawo zokuhlala zokwenyani. Sibale umgama phakathi kweendawo ze-GPS kunye ne-centroid yeekheyiji njengempazamo yokuma, saza sasebenzisa iimpazamo zokuma ze-95% (95th percentile) ukuchaza ukuchaneka. Impumelelo yokuma ingumndilili we-92.0%, ephezulu kakhulu kuneyezifundo zangaphambili. Iindawo azizange zisasazwe ngokulinganayo yiLocation Class (LC), apho iindawo ze-LC A kunye ne-B zibalwa kwi-88.7%. Impazamo yokuma ye-95% ebonwe kwiindawo ze-LC A (9–39 m) kunye ne-B (11–41 m) yayichanekile, ngelixa ukuya kuthi ga kwi-6.9–8.8% yeendawo ezikumgangatho ophantsi zifunyenwe kwi-LC C kunye ne-D enempazamo yokuma ye-> 100 m okanye ngaphezulu kwe-1,000 m. Impumelelo yokubeka kunye nokuchaneka kwakwahlukile phakathi kweendawo zovavanyo, mhlawumbi ngenxa yomahluko kwisakhiwo sezityalo. Ngoko ke, sithi abathumeli abavavanyiweyo banokubonelela ngenani elikhulu ledatha esemgangathweni ophezulu kwizifundo ezicwangcisiweyo, kunye nenani leendawo ezikumgangatho ophantsi ezifuna ingqwalasela. Sicebisa ukuba kuxelwe i-HPOD (horizontal dilution of precision) okanye i-PDOP (positional dilution of precision) endaweni ye-LC njengomlinganiselo wokuchaneka kwendawo kwindawo nganye ukuqinisekisa ukuchongwa kunye nokuhluzwa kweendawo ezingenakwenzeka.
