Dabagalka GPS-ka ayaa si sii kordheysa loogu isticmaalay daraasadaha duurjoogta sannadihii la soo dhaafay, laakiin waxqabadkeeda si buuxda looma qiimeyn, gaar ahaan kuwa cusub ee la horumariyay gudbiyaasha miisaanka yar. Waxaan qiimeynay waxqabadka sideed gudbiye GPS ah oo lagu sameeyay Shiinaha anagoo ku dhejinay Crested Ibises Nipponia nippon oo ku xaddidan laba qafis oo isbarbardhig ah oo ku ekaanaya degaannada dhabta ah. Waxaanu xisaabinay masaafada u dhaxaysa goobaha GPS-ka iyo xarunta dhexe ee qafisku sidii khaladka meelaynta, waxaanan isticmaalnay 95% (95th boqolkiiba) khaladaadka meelaynta si loo qeexo saxnaanta. Guusha meelaynta ayaa celcelis ahaan noqotay 92.0%, taas oo aad uga badan tii daraasadihii hore. Goobaha si siman looma qaybin goobta Class (LC), iyadoo goobaha LC A iyo B ay ka yihiin 88.7%. Khaladka meelaynta 95% ee lagu arkay meelaha LC A (9-39 m) iyo B (11-41 m) aad bay sax u ahayd, halka ilaa 6.9–8.8% ee meelaha tayadoodu liidato lagu arkay LC C iyo D oo leh> 100 m ama xataa> 1,000 m khalad meelaynta. Meelaynta guusha iyo saxnaanta way ka duwanaayeen inta u dhaxaysa goobaha tijaabada, malaha waxaa sabab u ah kala duwanaanshaha qaab dhismeedka dhirta. Markaa, waxaanu ku doodaynaa in gudbiyaasha la tijaabiyay ay bixin karaan tiro badan oo xog tayo sare leh oo loogu talagalay daraasado heersare ah, iyo tiro goobo tayadoodu liidato oo u baahan feejignaan. Waxaan soo jeedineynaa in HPOD (dilution horizontal of precision) ama PDOP (masifeynta booska saxda ah) lagu soo warramo bedelkii LC si loo cabbiro saxnaanta goobta goob kasta si loo hubiyo aqoonsiga iyo shaandhaynta meelaha aan macquul ahayn.
