Inkcazelo ye-GNSS RTK: Indlela Ukuchana kwe-Centimeter kusebenza ngayo
I-GPS eqhelekileyo yeselula ichana kwiimitha ezimbalwa, elungele ukukhangela indlela kodwa engasebenziyo kuhlolo lwemihlaba. I-RTK, okanye intshukumo ye-Real-Time Kinematic, yehlisela kakhulu ukuchana kwiisentimitha ngokusebenzisa umamkeli wesibini omileyo ukulungisa iziphoso ngoko nangoko.
Iyimfihlo kukuthethanisa amaza. Isitishi sasezantsi (base station) esibekwe kwindawo eyaziwa ngqo sifumana amaza omfanekiso-ngqondweni afana nawomamkeli ohambahambayo (rover), sibala isiphoso kumanani afunyenweyo, kwaye sasaza uluvo lokulungisa umamkeli alusebenzise ngoko nangoko.

Indlela eisebenza ngayo intshukumo ye-RTK
Ukwakhiwa kwesitishi sasezantsi
Umamkeli ubekwa kwixabiso elichanekileyo leqondo, mhlawumbi elihlolwe okanye elibhekiselwe kwiphawu eliyaziwayo.
Ukwamkelwa kwamaza e-satellite
Zombini isitishi sasezantsi ne-rover bamkela amaza kwiseti enye yesasathelayithi ye-GNSS ngexesha elinye.
Ukubalwa kokulungiswa
Isitishi sasezantsi sithethanisa indawo eyaziwayo ngokuchasene nendawo ebalwe kumaza esasathelayithi ukufumana isiphoso sangoku.
Umsasazo kokulungiswa
Isitishi sasezantsi sithumela le datha yokulungisa kwi-rover ngomathotholo okanye nge-intanethi ngoko nangoko.
Kufunyenwe isisombululo esileyo (Fixed)
I-rover isebenzisa ukulungiswa, isombulula ukungaqiniseki ukufumana indawo emileyo echaneke kwiisentimitha.
Isisombululo esileyo se-RTK sinikezela ukuchana kweisentimitha, kodwa isisombululo se-float, esenzeka xa isixokelelwano singakwazi ukusombulula ngokupheleleyo ukungaqiniseki kwamaza, singanikeza ukuchana kwenqanaba le-decimeter kuphela. Hlala uqinisekisa ubume obumileyo (fixed) ngaphambi kokubhala amaphuzu uhlolo.
I-GPS ikuxelela ngokulinganisa ukuba uphi. I-RTK ikuxelela ngqo ukuba uphi, kuye kwiisentimitha ezimbalwa.
Kutheni le nto i-RTK ibalulekile kuhlolo lwemihlaba
Loo nqaku lithile lentshukumo echanekileyo, ukusuka kwiikona zemida ukuya kumikhombo yokwakha, litsalela kule ngxaki yobudlelwane bokulungiswa kwe-base ne-rover ukuba isebenze kakuhle. Iqela lethu le- DGPS survey neequmrhu ze-drone zisebenzisa intshukumo ye-RTK njengesiseko esingundoqo sokuqokelela idatha ye- GIS mapping kuyo yonke iprojekthi.
Ingaba udinga idatha yomeleleyo ye-survey echaneke kwiisentimitha?
Sichazele ngeprojekthi yakho kwaye sizakucacisa indlela yethu yentshukumo ye-RTK.
Imibuzo Ebuzwa Enkulu
I-RTK imele i-Real-Time Kinematic, indlela yentshukumo ye-GNSS esebenzisa ukulungiswa kwesitishi sasezantsi ukufezekisa ukuchana kweisentimitha.
I-GPS eqhelekileyo ichana kwiimitha ezimbalwa, ngelixa i-RTK isebenzisa ukulungiswa kwesitishi sasezantsi ukuzisa loo nqanaba kwiisentimitha ngoko nangoko.
Isitishi sasezantsi ngumamkeli obekwe kwindawo eyaziwa ngqo obala iziphoso kwamaza esasathelayithi kwaye asasaze izilungiso kubamamkeli be-rover.
Isisombululo se-fixed sifezekisa ukuchana kweisentimitha ngokupheleleyo, ngelixa isisombululo se-float senzeka xa ukungaqiniseki kungakwazanga ukusombululwa, okuzisa ukuchana kwenqanaba le-decimeter.
Ewe, imigama emide inganciphisa ukuthenjwa kokulungiswa kunye nokuchana, yiyo loo nto izitishi zasezantsi zigcinwa kwindawo eamkelekileyo kufuphi nommandla wohlolo.
Idatha yokulungisa isingiswa ngomathotholo kwizilungiselelo zalapha gqolo okanye nge-intanethi kwimimandla ebanzi.
Inethiwekhi ye-CORS yisixokelelwano sezitishi zereferensi ezimileyo ezilungiselela izilungiso ze-RTK kwimimandla ebanzi ngaphandle kwemfuneko yesitishi sasezantsi sahluko.
Ewe, intshukumo ye-RTK ne-PPK zidityaniswa kwinkqubo yokusebenza yee-drone ukufumana ukuchana okuphezulu ngaphandle kwamaphuzu amaninzi olawulo omhlaba.
Imo yewonga engalunganga ingachaphazela umgangatho wamaza ngamanye amathuba, nangona izixokelelwano ze-RTK zamanje zinamandla phantsi kwemozulu eqhelekileyo.
Intshukumo ye-RTK enesisombululo esileyo (fixed) inika ukuchana okufunekayo kwimisebenzi yemida yasemthethweni, nangona imigangatho yobuchwepheshe zalapha neendlela zokuqinisekisa zisasebenza.
Le layini igcinelwe iinkokheli zeeprojekthi kuphela. Nceda ungatsaleli simfundo, uqeqesho okanye imibuzo yemisebenzi.
