Variation

Navigational Algorithms

Mayelana nalolu hlelo lokusebenza

I-VARIATION yosuku lwamanje.
Isetshenziswa ekuzulazuleni ngekhampasi kazibuthe.
-
Ukwehluka i-engeli ephakathi kwe-meridians kazibuthe neyezwe kunoma iyiphi indawo, evezwa ngamadigri empumalanga noma entshonalanga ukukhombisa isiqondiso senyakatho kazibuthe ukusuka enyakatho yangempela. Kubizwa ngokuthi I-MAGNETIC VARIATION lapho kudingeka umehluko ukuvimbela ukungaqondakali okungaba khona. Ibizwa nangokuthi MAGNETIC DECLINATION. (Bowditch)

Uhlelo lokusebenza lusebenzisa i-World Magnetic Model: WMM2025.
Imodeli entsha isebenza kusukela ngomhlaka-13/11/2024 kuya ku-31/12/2029.

Indawo yakho yokugcina igcinwa ngokuzenzakalelayo.
- Imvume yokugcina iyadingeka ukuze ulondoloze isikhundla sakho.

ISIBALA SE-COURSE
Ikhampasi nenkambo yeqiniso.
UKUCHEZUKUKA AMA-COEFFICIENTS
I-Dev = A + B SIN(Ra) + C COS(Ra) + D SIN(2Ra) + E COS(2Ra)
Bala ama-coefficients A,B,C,D,E nge-Windows "Compass Magnetic" Windows, (itholakala kuwebhusayithi ye-Navigational Algorithms).
Wafake bese uwagcina. Uhlelo lokusebenza luzofunda idatha futhi isibali sesifundo sizokwazi ukubala ukuchezuka.


UKUHLANGANYELA KOMSEBENZISI
- Izinkinobho zokusondeza +/-
- Izinhlobo zamamephu: ezejwayelekile, indawo kanye nesathelayithi
- Indawo ye-GPS. ("Indawo" Imvume yohlelo lokusebenza kufanele ivunyelwe. Vula i-GPS yakho, bese ukutholwa kwendawo okuzenzakalelayo kungenzeka)

Imicimbi kumephu:
• Ukuchofoza Okude: kwengeza umaki ngokuhluka endaweni yosuku lwamanje.
• Thinta uphawu ukuze ubone ulwazi.
• Ukuthinta kwemephu: https://developers.google.com/maps/documentation/android-sdk/controls
