Kutsata GPS kwakhala kukugwiritsidwa ntchito kwambiri pa kafukufuku wa zinyama zakuthengo m'zaka zaposachedwa, koma magwiridwe ake sanayesedwe mokwanira, makamaka pa ma transmitter opepuka omwe apangidwa kumene. Tinayesa magwiridwe antchito a ma transmitter asanu ndi atatu a GPS omwe adapangidwa ku China powalumikiza ku Crested Ibises Nipponia nippon omwe ali m'makhola awiri okhazikika omwe amatsanzira malo enieni okhala. Tinawerengera mtunda pakati pa malo a GPS ndi centroid ya makhola ngati cholakwika choyimilira, ndipo tinagwiritsa ntchito zolakwika za 95% (95th percentile) kuti tifotokoze kulondola. Kupambana kwa malo kunali pafupifupi 92.0%, komwe ndi kwakukulu kwambiri kuposa kwa kafukufuku wakale. Malo sanagawidwe mofanana ndi Location Class (LC), pomwe malo a LC A ndi B anali 88.7%. Cholakwika cha 95% choyimilira m'malo a LC A (9–39 m) ndi B (11–41 m) chinali cholondola kwambiri, pomwe mpaka 6.9–8.8% ya malo osalimba adapezeka mu LC C ndi D ndi cholakwika cha 100 m kapena ngakhale cha 1,000 m. Kupambana ndi kulondola kwa malo kunali kosiyana pakati pa malo oyesera, mwina chifukwa cha kusiyana kwa kapangidwe ka zomera. Chifukwa chake, tikunena kuti ma transmitter oyesedwawo angapereke chiwerengero chachikulu cha deta yapamwamba kwambiri yophunzirira bwino, ndi malo angapo osabwino omwe amafunika kusamalidwa. Tikupangira kuti HPOD (horizontal dilution of precision) kapena PDOP (positional dilution of precision) inenedwe m'malo mwa LC ngati muyeso wa kulondola kwa malo pa malo aliwonse kuti zitsimikizire kuzindikira ndi kusefa malo osayembekezereka.
