azvuzi

Lokhu yingakho i-accelemerometer ingabangane abahle be-gyroscopes: ngoba bangabona izikhombo ezinhle kakhulu "ezansi" (okungenani, lapho zisesimweni sokudonsela phansi komhlaba).

Kahle, ngokuvamile ukukhuluma. Ukusuka ngomzuzwana kuya kwesinye, kuthola amandla adonsela phansi, ukusheshisa okuqondile, ama-centrifugal, amabutho akhiqizwa ukujikeleza, ukudlidliza, umsindo futhi, iziphambeko zenzwa.

Ngakho-ke, naphezu kwesilinganiso esiphezulu sesampula nokunemba okuhle kwezinzwa ze-MEMS (imvamisa njenge-gyroscopes), idatha ye-accelerometer isenye yedatha enomsindo nengathembekile. Ithole "izibonakaliso" eziningana okumele zivunyelwe. Kepha kungukuzwela kwazo zonke lezi zimpawu ezahlukahlukene ezenza kube ngumhlaba wonke kangaka - zingezwa konke.

Kunezinyathelo ezimbili zokuhlanganiswa zokusheshisa kusuka esimweni esifuna ngempela ukwazi, ngakho-ke kufanele sifingqe ama-Deltas kanye nemigqa yephutha, kusukela lapho kulinganiselwa khona ngejubane elilinganisiwe, bese kufanele senze futhi ukuthola isikhundla esilinganiselwe. Amaphutha ayaqhubeka nokuqongelela.

Kungaleso sizathu-GPS ungumngane we-accelerometer: ngoba izokwenziwa "zero" Iphutha elikhulayo lephutha, njengoba nje i-accelerometer ngobumnene i-Ackerometer inezimpawu ze-Azimuth ze-gyroscope.

amagathane

Ikhampasi enhle akufanele kunganakwa. Kodwa-ke, njenge-accelerometer, imvamisa isetshenziswa njengendlela yokulawula ye-Gyro Drift ende. Ukwazi ukuthi yiluphi uhlangothi oluwusizo luwusizo ngokwengeziwe kunokwazi ukuthi yiluphi uhlangothi oluyi-magnetic asenyakatho - kodwa nale mibili, singazi isikhundla sethu esihle ngempela emhlabeni.

Zivame ukubhabhangqwa nabamukelayo ze-GPS, ngoba baphinde balwa nobuthakathaka obukhulu bomunye nomunye, kepha bahambisana kahle kwezinye izici. Umuntu unikeza isikhundla esihle kakhulu, kanti omunye unikeza ukuqondisa okuhle kakhulu.
