Uphando lwe-DGPS vs GPS Eqhelekileyo: Ukuchaneka, Iindleko Nokukhetha Okuchanekileyo
I-GPS yefowuni inokukubeka kumgama omalunga neemitha ezili-10 ukusuka kwindawo okuyo ngenene, nto leyo eyoneleyo ekufumaneni indawo yokutyela kodwa engenamsebenzi kwaphela ekumakisheni imida esemthethweni yomhlaba. Lo msantsa ulingana nobubanzi begumbi elincinci okanye isakhiwo sesona sizathu sokuba uphando lwe-DGPS lube lukhula njengomsebenzi wobunjineli owahlukileyo kwi-GPS eqhelekileyo.
Zombini i-GPS eqhelekileyo kunye ne-DGPS zisebenzisa iimpawu zesathelayithi, kodwa zisisombulula iimfuno zobunjineli ezahluke ngokupheleleyo. I-GPS eqhelekileyo ibonelela ngendawo eqikelelweyo ngokukhawuleza kwaye simahla. Ngelixa i-DGPS yongeza umaleko wokulungisa ngexesha lokwenyani oguqula olo qikelelo lube kukungqinelana komgangatho wobunjineli.
Isebenza Kanjani I-GPS Eqhelekileyo
Isamkeli se-GPS esiqhelekileyo sibala indawo ngeempawu zesathelayithi kuphela. Ukulibaziseka komoya kubangela impazamo yeemitha ezi-3 ukuya kwezi-10, kwaye ngaphandle kokulungiswa inokudlula iimitha ezili-15. Oku kulungele ukufumana indlela kodwa akwamkelekanga ekumakisheni imida yomhlaba okanye iziseko zokwakha.
Indlela I-DGPS Ephucula Ngayo Ukuchaneka
Uphando lwe-DGPS lusebenzisa izamkeli ezibini: isikhululo esisisiseko (Base Station) esimiselwe kwindawo eyaziwayo ngokuthe ngqo, kunye nesixhobo esihambahambayo (Rover) ebaleni. Isikhululo esisisiseko sibala impazamo yesathelayithi ngexesha kwaye sithumela izilungiso kwi-rover. Isiphumo lulungelelwano olusukela kwisentimitha e-1 ukuya kwisiqingatha semitha.
I-GPS Eqhelekileyo
- Ukuchaneka: Iimitha ezi-3 ukuya kwezi-15
- Isamkeli esinye ngaphandle kwenkqubo yokulungisa
- Simahla okanye ixabiso eliphantsi kakhulu
- Ilungele ukukhangela indlela nendawo ngokubanzi
Uphando lwe-DGPS
- Ukuchaneka: Isentimitha e-1 ukuya kwi-0.5 yemitha
- Inkqubo ephindwe kabini ye-Base Station ne-Rover
- Izixhobo zobunjineli eziphezulu kunye neendleko zobungcali
- Ilungele imida esemthethweni yomhlaba kunye nezakhiwo
Uthelekiso Lweendleko Neendlela
| Inkalo Yothelekiso | I-GPS Eqhelekileyo | Uphando lwe-DGPS |
|---|---|---|
| Ukuchaneka okuqhelekileyo | Iimitha 3 ukuya kwezi-15 | Isentimitha 1 ukuya kwi-0.5 yemitha |
| Izixhobo ezifunekayo | Ifowuni / Isamkeli esiqhelekileyo | Base station + Rover yomgangatho wophando |
| Iindleko | Phantsi kakhulu (ikwifowuni) | ₹8,000 ukuya kwi-₹25,000 ngosuku okanye nge-km |
| Ukusetyenziswa okona kulungileyo | Ukukhangela indlela, ukurekhoda jikelele | Uphando lomhlaba, ukumakisha imida, izakhiwo |
Kwiiprojekthi zomhlaba nezoburhulumente e-India nakwamanye amazwe, i-DGPS sisinyanzelo kuba impazamo ye-GPS eqhelekileyo inkulu kakhulu ukuba ingasetyenziselwa izigqibo zomthetho okanye zobunjineli.
Ixesha Olufuna Ngalo Ngokwenene I-DGPS Endaweni ye-GPS Eqhelekileyo
Ukuba iziphumo zophando zichaphazela imida esemthethweni yomhlaba okanye uyilo lokwakha, i-DGPS iyimfuneko. I-GPS eqhelekileyo ilungele kuphela apho impazamo yeemitha ezimbalwa ingenabungozi. Inkonzo yethu ye-DGPS and RTK survey yenzelwe ukuhlangabezana nemigangatho engqongqo yokuchaneka.
Umahluko phakathi kwe-GPS ne-DGPS ngumahluko phakathi kokwazi ngokuthelekelela apho ukhoyo kunye nokwazi ngokuchanekileyo apho umda womhlaba wakho uphela khona.
Amanqaku okulawula umhlaba (GCPs) amiselwe nge-DGPS akwangalawo enza idatha yeedrone ifikelele kumgangatho wobunjineli kwiimephu ze-topographic.
Ungaze usebenzise idatha ye-GPS yefowuni njengobungqina kwiingxabano zomhlaba okanye ekucwangciseni ukwakha. Impazamo yayo ayivumelekanga ngokwasemthethweni okanye kubugcisa.
Ingaba ufuna ukuchaneka komgangatho wophando kwiprojekthi yakho?
Sixelele ngendawo kunye nenjongo yakho, kwaye siya kuqinisekisa ukuba i-DGPS, i-RTK okanye indlela edityanisiweyo yeyona ifanelekileyo.
Imibuzo Ebuzwa Rhogo (FAQ)
I-GPS eqhelekileyo inempazamo yeemitha ezi-3 ukuya kwezi-15, ngelixa i-DGPS ifikelela kwi-1 cm ukuya kwi-0.5 m ngoncedo lwe-Base Station.
Kuba i-DGPS isebenzisa i-Base Station kwindawo eyaziwayo ukulungisa iimpazamo zesathelayithi ngoko nangoko.
Hayi. Impazamo yeemitha ezininzi yefowuni ayifanelekanga kwimida esemthethweni yomhlaba.
Ngokuqhelekileyo isusela kwi-₹8,000 ukuya kwi-₹25,000 ngosuku, okanye i-₹1,500 ukuya kwi-₹4,000 ngekhilomitha kwiiprojekthi zeendlela.
Kufuneka izamkeli ezibini zomgangatho wophando: i-Base Station kunye ne-Rover.
Zisondelene kakhulu. I-RTK inika izilungelelanisi ezilungisiweyo kwangoko ebaleni, ngelixa ezinye iinkqubo ze-DGPS zilungisa idatha emva kokusebenza.
Ewe, iiprojekthi zikarhulumente zifuna ukuchaneka kwe-DGPS ukukhusela ezomthetho nezobunjineli.
Ewe, i-DGPS ixhomekeke kwisathelayithi nakunxibelelwano lwerediyo ngaphandle kwe-intanethi yefowuni.
Ukuqinisekisa imida esemthethweni ewe, kuba impazamo yeemitha ezimbalwa inokubangela iingxabano ezinkulu.
Zombini zinika ukuchaneka okuphezulu. I-DGPS ikhawuleza kakhulu kwiindawo ezivulekileyo, ngelixa i-Total Station ilungele iidolophu ezinemiqobo.
Le nombolo ibekelwe imibuzo yeeprojekthi kuphela. Nceda ungaqhagamshelani ngezicelo zomsebenzi okanye uqeqesho.
