Ua hoʻohana nui ʻia ka mākaʻikaʻi GPS no nā haʻawina holoholona hihiu i nā makahiki i hala iho nei, akā ʻaʻole i loiloi piha ʻia kāna hana, ʻoi aku hoʻi no nā mea hoʻouna māmā hou. Ua loiloi mākou i ka hana o nā mea hoʻolele GPS ʻewalu i hoʻomohala ʻia ma Kina ma o ka hoʻopili ʻana iā lākou i Crested Ibises Nipponia nippon i hoʻopaʻa ʻia i ʻelua mau hale hoʻokipa e hoʻohālike ana i nā wahi noho maoli. Ua helu mākou i ka mamao ma waena o nā wahi GPS a me ka centroid o nā hīnaʻi e like me ke kuhi kūlana, a ua hoʻohana i ka 95% (95th percentile) nā hewa kūlana e wehewehe i ka pololei. He 92.0% ka holomua o ke kūlana, ʻoi aku ka kiʻekiʻe ma mua o nā haʻawina mua. ʻAʻole i māhele like ʻia nā wahi e ka Papa Wahi (LC), me ka helu ʻana o nā wahi LC A a me B no 88.7%. ʻO ka 95% ka hewa o ka hoʻonohonoho ʻana i ʻike ʻia ma nā wahi o LC A (9–39 m) a me B (11–41 m) ua pololei loa, a hiki i ka 6.9–8.8% o nā wahi maikaʻi ʻole i ʻike ʻia ma LC C a me D me ka > 100 m a i ʻole > 1,000 m ka hewa kūlana. He ʻokoʻa ka holomua a me ka pololei o ka hoʻonohonoho ʻana ma waena o nā kahua hoʻāʻo, ma muli paha o ka ʻokoʻa o ke ʻano o nā mea kanu. No laila, ke hoʻopaʻapaʻa nei mākou e hiki i nā transmitters i hoʻāʻo ʻia ke hāʻawi i kahi hapa nui o ka ʻikepili kiʻekiʻe no nā haʻawina maikaʻi, a me kekahi mau wahi maikaʻi ʻole e pono ai ka nānā. Manaʻo mākou e hōʻike ʻia ka HPOD (horizontal dilution of precision) a i ʻole PDOP (positional dilution of precision) ma kahi o ka LC ma ke ʻano he ana o ka pololei wahi no kēlā me kēia wahi e hōʻoia i ka ʻike a me ke kānana ʻana i nā wahi implausible.
