Kwilizwe leTekhnoloji yeGeolicatial, i-Gnss ye-Gns (i-SAGT yeSoter Nagallite), i-RTK (ixesha lokwenyani), kwaye i-GPS (i-GPS (i-GPS (i-GPS (imele ukuqondisa ukuchaneka kwendawo iinkqubo. Njengoko imfuno yendawo yendawo echanekileyo iyaqhubeka nokukhula kwamashishini, abathengi kufuneka baqonde ubunzima be-RTK kunye nendlela echaphazela ngayo ukusebenza kwabo.
Ukuqonda i-gnss, i-GPS kunye ne-RTK
Ngaphambi kokuba uhlale kwi-RTK ukuchaneka kwe-RTK, iikhonsepthi ezisisiseko ze-GNS, i-GPS, kunye ne-RTK kufuneka icaciswe.
Ii-GNSs zibhekisa kwiqela lesatellite ezibonelela ngendawo kunye nexesha lolwazi kwindawo afumana kuyo i-Gnss Amkeli naphi na emhlabeni. Oku kubandakanya iinkqubo ezahlukeneyo ezinjenge-GPS, glodass yaseRussia, eYurophu yeGalileo, kunye ne-chinese beidou. Elinye lala nkqubo linegalelo ekuchanekeni ngokubanzi kunye nokuthembeka kwedatha yokubeka idatha.
I-GPS yiseti ye-GNS kunye nenkqubo eyaziwayo eyaziwayo, ephuhliswe yi-US iqulathe inethiwekhi yesatellite edlulisela imiqondiso eyahlukeneyo, ichonge idigri yabo yokuchaneka kwamanqanaba ahlukeneyo okuchaneka.
I-RTK, okanye indawo yokwenyani ye-kinematic, yitekhnoloji ephucula ukuchaneka kwendawo ye-gnss. Ngokusebenzisa isikhululo esisiseko esisigxina kunye neSoftware, i-RTK inokufezekisa ukuchaneka kwinqanaba lesenti. Oku kuyingenelo ikakhulu kwizicelo ezifuna ukuchaneka okuphezulu, ezinjengokuphononongwa, ezolimo, kunye nolwakhiwo.
Ukubaluleka kokuchaneka kwe-RTK
Ukuchaneka kwe-RTK yinto ephambili kubathengi abajonga izisombululo ze-Gnss. Inqanaba lokuchaneka imfuneko ihlala ixhomekeke kwisicelo esithile. Umzekelo, ekuphoxekeni, impazamo yeesentimitha ezimbalwa inokukhokelela kumanyathelo abonakalayo kwimilinganiselo yomhlaba, ngelixa kwezolimo, isikhundla esichanekileyo sinokwandisa ukutyala kunye nokuvuna.
Izinto ezichaphazela ukuchaneka kwe-RTK
- Umgangatho weSiseko seSiseko: Ukuchaneka kwendawo ye-RTK kuxhomekeke kakhulu kumgangatho wesikhululo seSiseko. Isikhululo esihleweyo nesibekwe kakuhle sinokuphucula kakhulu ukuchaneka kwedatha edluliselwe kumhlamo omiselweyo.
- Ukuphazamiseka kwesiginali: Izinto zokusingqongileyo ezifana nezakhiwo, imithi kunye neemeko ze-qumossic zinokuphazamisa imiqondiso ye-gns. Olu phazamiso lunokubangela ukungachaneki. Iinkqubo ze-RTK zenzelwe ukunciphisa ezinye zezi ziphumo, kodwa abathengi kufuneka balwazi amandla okupheliswa kwesiginali kwiindawo ezinzima.
- Umgama ukusuka kwisitayile esisesikweni: Ukuqhubeka nomsebenzi ophantsi kweselula kuvela kwisikhululo seziseko, amathuba amakhulu eempazamo. Iinkqubo ze-RTK zihlala zisebenza kakuhle ngaphakathi kwe-10 ukuya kwi-20 yeekhilomitha zesikhululo esisesikweni. Ngaphandle kolu luhlu, ukuchaneka kwe-verade kakhulu.
- Ijometri ye-satellite: Ulungelelwaniso lwesathelayithi esibhakabhakeni nako kuchaphazela ukulungisa ngokuchanekileyo. I-geomellite elungileyo ye-satellite (i-satellites isasazeka esibhakabhakeni) inokubonelela ngedatha engcono kwi-jometri ye-gatellite embi (i-satellites idityaniswe kunye).
- Umgangatho wamamkeli: Umgangatho we-GnsS Umamkeli we-Gns ngokwawo udlala indima ebalulekileyo ekufezekiseni ukuchaneka kwe-RTK. Abahlali abakumgangatho ophezulu baxhotywe nge-algorithms ekhethekileyo kunye nezakhono zokulungisa ukuphucula ukuchaneka kwedatha.
Izibonelelo zokuchaneka kwe-RTK
Ukutyala imali kwitekhnoloji ye-RTK kunokubonelela ngezibonelelo ezininzi kumashishini kunye neengcali ezixhomekeke kwidatha yendawo echanekileyo. Ezinye zezi zibonelelo zibandakanya:
- Ukunyusa ukusebenza kakuhle: Ukuchaneka kwenqanaba lesentimeter, iinkqubo ze-RTK zinokutshintsha imisebenzi, kwaye zinciphise intlawulo, kwaye ziphucule imveliso efana nezokwakha nezolimo.
- Ukugcina iindleko: ngokunciphisa iimpazamo kunye nokuchaneka kwemilinganiselo yokulinganisa, itekhnoloji ye-RTK inokubonelela ngemali eninzi kakhulu ngokuhamba kwexesha. Oku kubaluleke kakhulu kumashishini apho ukuchaneka kubalulekile.
- Ukwenziwa kwezigqibo eziphuculweyo:
Yintoni ekufuneka ithathelwe ingqalelo
Xa ujonga ukuthenga inkqubo ye-RTK, abathengi kufuneka bavavanye izinto ezininzi eziphambili:
- Iimfuneko zesicelo: Chonga inqanaba lokuchaneka okufunekayo kwisicelo sakho esithile. Oku kuyakukhokela ukhetho lwakho lweenkqubo ze-RTK kunye nezixhobo.
