Kutsata kwa GPS kwakhala kukugwiritsidwa ntchito kwambiri pamaphunziro a nyama zakuthengo m'zaka makumi angapo zapitazi, koma magwiridwe ake sanayesedwe mokwanira, makamaka pama transmitter omwe angopangidwa kumene. Tidawunika magwiridwe antchito a ma transmitters asanu ndi atatu a GPS opangidwa ku China powalumikiza ku Crested Ibises Nipponia nippon yotsekeredwa m'makola awiri otengera malo enieni. Tidawerengera mtunda wapakati pa malo a GPS ndi centroid ya makola ngati vuto la malo, ndikugwiritsa ntchito zolakwika za 95% (95th percentile) kuti tifotokoze zolondola. Kupambana kwamakhalidwe kunali 92.0%, komwe ndikwambiri kuposa maphunziro am'mbuyomu. Malo sanagawidwe mofanana ndi Malo Class (LC), ndi malo a LC A ndi B omwe amawerengera 88.7%. Zolakwika zowoneka 95% za malo a LC A (9-39 m) ndi B (11-41 m) zinali zolondola, pomwe mpaka 6.9-8.8% ya malo osawoneka bwino adapezeka mu LC C ndi D ndi> 100 m kapena> 1,000 m cholakwika choyika. Kuyika bwino ndi kulondola kunali kosiyana pakati pa malo oyesera, mwina chifukwa cha kusiyana kwa zomera. Chifukwa chake, tikutsutsa kuti ma transmitters oyesedwa atha kupereka gawo lalikulu lazinthu zapamwamba kwambiri zamaphunziro apamwamba, komanso malo angapo opanda pake omwe amafunikira chisamaliro. Tikulangiza kuti HPOD (dilution yopingasa yolondola) kapena PDOP (positional dilution of precision) inenedwe m'malo mwa LC monga muyeso wa malo olondola a malo aliwonse kuti atsimikizire kuzindikiridwa ndi kusefa kwa malo osatheka.
