Altimetro Professionale

Nicola Imperati

Mayelana nalolu hlelo lokusebenza

Le-altimeter ngokuxhuma nge-GPS yakho; Ivumela ukwazi ngesikhathi sangempela:

- Ububanzi
- Isilinganiso
- Ukuphakama kumamitha ayi-8000
- Isikhundla samanje, esihlobene: Nombuso, Idolobha, Izwe, Ikhodi Yeposi.

Eqinisweni, i-GPS yisihumusho se-Global Positioning System, ngakho-ke uhlelo lokuma komhlaba jikelele. Ngenxa ye-GPS kuyenzeka ukuthi uthole indawo nobude bezinto nabantu. Konke kwenzeka ngama-satellite abekwe ekuzungezeni komhlaba futhi akuvumela ukuba wazi indawo ngqo yendawo nganoma yisiphi isikhathi. Ama-satellites aqukethe iwashi le-athomu elibala inkulungwane yomzuzwana isikhathi esedlula esicelweni esenziwe ngumamukeli we-GPS kuya ngezimpendulo ezitholwe ama-satellites uqobo.

Emhlabeni jikelele kunezinhlelo ezihlukile zokuma komhlaba jikelele. Okudume kakhulu yi-NAVSTAR isichazamazwi se-Navigation System ene-Timing And Ranging Global Positioning System futhi yilokho sonke esikubiza nge-GPS. Idalwe uMnyango Wezokuvikela eMelika kwezempi, idume ngokusetshenziswa kwezenhlalo. Uhlelo lwe-NAVSTAR lusebenzisa isiphuphutheki sama-31. Ngaphezu kohlelo olwenziwe yi-United States, kukhona nabanye: I-GLONASS isichazamazwi se-GLObal NAvigation Satellite System futhi uhlelo lokuma olusetshenziswa amaRussia. Kwenziwe isiphuphutheki sama-31, lapho kungama-24 kuphela asebenza khona. I-Europe nayo inohlelo lwayo lokuma (i-GALILEO), elisebenza kusukela ngo-2016 futhi liqukethe iziphuphutheki ezingama-30. I-BEIDOU, ngakolunye uhlangothi, uhlelo olwakhiwa iChina ne-IRNSS oluseNdiya.
