Nakong ea mehato e matla ea theknoloji, litsamaiso tsa ho tsamaisa likepe li ile tsa hlaha e le litšiea tsa motheo, tse tsamaisang tsoelo-pele e ngata, haholo-holo makaleng a bohlokoa haholo. Leeto la ho tloha tseleng e sa tloaelehang ea leholimo ho ea ho Inertial Navigation Systems (INS) e tsoetseng pele e bonts'a boiteko bo sa fetoheng ba batho ba ho batlisisa le ho supa ho nepahala. Tlhahlobo ena e kenella ka botebo ka har'a mechini e rarahaneng ea INS, e hlahlobang theknoloji ea morao-rao ea Fiber Optic Gyroscopes (FOGs) le karolo ea bohlokoa ea Polarization ho Boloka Fiber Loops.
Karolo ea 1: Ho Hlahlobisisa Mekhoa ea ho Tsamaisa ea Inertial (INS):
Inertial Navigation Systems (INS) e hlahella e le lithuso tsa ho sesa tse ikemetseng, tse khomphuthang boemo ba koloi ka nepo, sebaka sa eona, le lebelo la eona, ntle le matšoao a kantle. Litsamaiso tsena li lumellana le li-sensor tsa motsamao le tse potolohang, li hokahana ka mokhoa o sa reroang le mefuta ea likhomphutha bakeng sa lebelo la pele, boemo le chebahalo.
Archetypal INS e akaretsa likarolo tse tharo tsa mak'hadinale:
* Accelerometers: Lintlha tsena tsa bohlokoa li ngolisa lebelo la koloi, li fetolelang motsamao hore e be data e ka lekanyetsoang.
· Li-Gyroscopes: Kakaretso ea ho khetholla lebelo la angular, likarolo tsena ke tsa bohlokoa bakeng sa ho shebana le tsamaiso.
· Mojule oa Khomphutha: Setsi sa methapo ea INS, se sebetsana le lintlha tse ngata ho fana ka litlhahlobo tsa nako ea nnete.
Ho itšireletsa ha INS ho litšitiso tsa kantle ho etsa hore e be ea bohlokoa haholo makaleng a ts'ireletso. Leha ho le joalo, e loantšana le 'ho hoholeha' - ho bola ho nepahetseng butle-butle, ho hlokang litharollo tse tsoetseng pele joalo ka fusion ea sensor bakeng sa phokotso ea liphoso (Chatfield, 1997).
Karolo ea 2. Matla a Tšebetso a Fiber Optic Gyroscope:
Fiber Optic Gyroscopes (FOGs) e phatlalatsa nako ea phetoho ea kutlo e potolohang, e matlafatsang tšitiso ea leseli. Ka ho nepahala ha mantlha, li-FOG li bohlokoa bakeng sa ho tsitsisa le ho tsamaisa likoloi tsa sefofane.
Li-FOG li sebetsa ho phello ea Sagnac, moo khanya, e haolang ka makhaola-khang ka har'a khoele ea faeba e potolohang, e bonts'ang phetoho ea mohato e amanang le liphetoho tsa sekhahla sa ho potoloha. Mochini ona o fetotsoeng o fetolela ho metrics e nepahetseng ea lebelo la angular.
Likarolo tsa bohlokoa li kenyelletsa:
· Mohloli oa Leseli: Sebaka sa ho qala, hangata ke laser, se qalang leeto le tsamaeang le leseli.
· Coil ea fiber: Conduit ea optical e kopantsoeng, e lelefatsa tsela ea leseli, ka hona e holisa phello ea Sagnac.
· Photodetector: Karolo ena e lemoha mekhoa e rarahaneng ea tšitiso ea leseli.
Karolo ea 3: Bohlokoa ba Polarization Ho Boloka Loops tsa Fiber:
Polarization Maintaining (PM) Fiber Loops, quintessential bakeng sa FOGs, e netefatsa boemo bo tšoanang ba polarization ea leseli, e leng eona ntho e ka sehloohong e khethollang ho nepahala ha mokhoa oa tšitiso. Likhoele tsena tse khethehileng, tse loantšang ho hasana ha mokhoa oa polarization, ho matlafatsa kutloisiso ea FOG le bonnete ba data (Kersey, 1996).
Khetho ea likhoele tsa PM, tse laetsoeng ke maemo a tšohanyetso a ts'ebetso, litšoaneleho tsa 'mele, le kutloano ea tsamaiso, li susumetsa metrics e kholo ea ts'ebetso.
Karolo ea 4: Likopo le Bopaki ba Bopaki:
FOGs le INS li fumana menahano ho lits'ebetso tse fapaneng, ho tloha ho hlophisa lifofane tse sa sebetsoeng ho ea ho netefatsa botsitso ba cinema har'a ho se lebelle tikoloho. Bopaki ba ho ts'epahala ha bona ke ho romelloa ha bona ho Mars Rovers ea NASA, ho nolofaletsa ho sesa ka mokhoa o sireletsehileng oa kantle ho lefatše (Maimone, Cheng, le Matthies, 2007).
Mekhoa ea 'maraka e bolela esale pele sebaka se ntseng se hola sa mahlale ana, ka li-vector tsa lipatlisiso tse reretsoeng ho matlafatsa botsitso ba sistimi, matrices a nepahetseng, le pono e ikamahanyang le maemo (MarketsandMarkets, 2020).
