Correct altitude (geoid correc

I-GPS isebenzisa umhlaba obushelelezi obulula obizwa ngokuthi yi-ellipsoid ekumeni, kufaka nokuphakama. Kodwa-ke, iplanethi ayibushelelezi futhi ngakho-ke umehluko phakathi kokuphakama komsebenzisi kanye ne-GPS urefu kungenza amashumi amaningi amamitha!

Sisebenzisa idatha ye-Earth Gravitational Model 2008 (EGM2008) ye-NGA ukubala ukuphambuka kwe-geoid kusuka endaweni eyi-ellipsoid yanoma iyiphi indawo esemhlabeni woMhlaba. Yonke imininingo egciniwe igcinwa ngqo kuhlelo futhi ngakho lonke uhlelo lusebenza ngaphandle kwesidingo soxhumo lwe-Intanethi.

Ungasetha amanye amanani anjengokuzwela nezinyathelo zokulinganisa ukuze uthole imiphumela elungile kakhulu oyibona kugrafu ebonakalayo ngesikhathi sangempela.

Ngokuqondile kunalolu hlelo lokusebenza ngaphansi kwezimo ezijwayelekile ngeke uthole indawo yakho ephathekayo!

Qoqa izimpumelelo, landela amabhodi wabaphambili! Njalo ukubalwa kwamamitha! :)
