i-accelerometer

Yingakho ama-accelerometers engabangane abakhulu be-gyroscopes: ngoba angakwazi ukubona izinkomba ezinhle kakhulu "eziphansi" (okungenani, lapho zisesimweni sokudonsela phansi komhlaba).

Hhayi-ke, ngokujwayelekile. Ukusuka kwesinye isikhathi kuye kwesinye, ithola amandla adonsela phansi, ukusheshisa okuqondile, amandla aphakathi nendawo akhiqizwe ukuzungezisa, ukudlidliza, umsindo kanye, vele, ukukhubazeka kwenzwa.

Ngakho-ke, naphezu kwezinga eliphezulu lokusampula nokunemba okuhle kwezinzwa ze-MEMS (ezivamise ukuba zinhle njenge-gyroscopes), idatha ye-accelerometer isengenye yedatha enomsindo nengathembekile. Ithole "amasignali" ambalwa okumele angacaciswanga. Kodwa ukuzwela kwazo zonke lezi zimpawu ezihlukene okwenza kube yindawo yonke-ikwazi ukuzwa yonke into.

Kunezinyathelo ezimbili zokuhlanganisa zokusheshisa ukusuka endaweni esifuna ukuyazi ngempela, ngakho-ke kufanele sifinyeze imigqa eminingi ye-deltas nephutha, ukusuka ekusheshiseni okulinganiselwe kuya kwisivinini esilinganisiwe, bese kufanele sikwenze futhi ukuze sithole isilinganiso esilinganiselwe. isikhundla. Amaphutha aqhubeka enqwabelana.

Yingakho i-GPS ingumngane we-accelerometer: ngoba "izosusa" iphutha lendawo ekhulayo ngezikhathi ezithile, njengoba i-accelerometer ivala kancane iphutha le-azimuth ye-gyroscope.

i-magnetometer

Ikhampasi enhle akufanele ishaywe indiva. Kodwa-ke, njenge-accelerometer, imvamisa isetshenziswa njengendlela yokulawula ye-gyro drift yesikhathi eside. Ukwazi ukuthi iyiphi indlela eya phezulu kubaluleke kakhulu kunokwazi ukuthi iyiphi indawo engasenyakatho kazibuthe-kodwa ngalezi ezimbili, singakwazi ukwazi indawo yethu enhle ngempela emhlabeni.

Zivame ukubhangqwa nezamukeli ze-GPS, ngoba ziphinde zilwe nobuthakathaka bomunye nomunye, kodwa zihambisana eduze kwezinye izici. Omunye unikeza indawo enhle kakhulu, kanti enye inikeza isiqondiso esihle kakhulu.
