Gukurikirana GPS byakoreshejwe cyane mubushakashatsi bwibinyabuzima mu myaka ya vuba aha, ariko imikorere yabyo ntabwo yasuzumwe neza, cyane cyane kubohereza amashanyarazi yoroheje. Twasuzumye imikorere ya transmitteri umunani za GPS zatejwe imbere mubushinwa tubahuza na Crested Ibises Nipponia nippon igarukira mu kasho abiri yo kumenyekanisha yigana ahantu nyaburanga. Twabaze intera iri hagati ya GPS na centroid ya cage nkikosa ryumwanya, kandi twakoresheje amakosa ya 95% (95th centile) kugirango tumenye neza. Intsinzi yimyanya yagereranije 92,0%, iri hejuru cyane yubushakashatsi bwabanje. Ibibanza ntibyatanzwe neza na Class Class (LC), hamwe na LC A na B bingana na 88.7%. Ikosa ryagaragaye 95% mu mwanya wa LC A (m 9-39 m) na B (11-41 m) byari ukuri rwose, mugihe abagera kuri 6.9-8.8% by’ahantu habi hatagaragara byagaragaye muri LC C na D hamwe na> 100 m cyangwa ndetse na> 1.000 m. Gutsindira intsinzi nukuri byari bitandukanye hagati yikizamini, birashoboka bitewe nuburyo butandukanye mumiterere yibimera. Rero, twemeza ko imiyoboro yapimwe ishobora gutanga igice kinini cyamakuru yujuje ubuziranenge kubushakashatsi bunini, hamwe n’ahantu hatari hake hakenewe kwitabwaho. Turasaba ko HPOD (horizontal dilution of precision) cyangwa PDOP (dilution de positif de positif de precision) yatangazwa aho kuba LC nkigipimo cyerekana neza aho buri hantu hagamijwe kumenya no gushungura ahantu bidashoboka.
