Umzekelo: GLH130-40

I-Nautical sextant ngasemva kwesakhelo esimise okwefeni enesiphatho sokubamba ukusetyenziswa, enengalo eshukumayo kwisakhelo, Umfanekiso wengalo luphawu olubonisa ukuba isipili esiphezulu; semi- ebonisa isipili esinyuswe kwi-sextant horizon ukuya ekhohlo ( embindini , n teleskopu 's ) , ecaleni kwesipili kuza isihluzo se-horizon ukuze sisetyenziswe xa kusenziwa umlinganiselo welanga eliqaqambileyo kunye nezinye izidalwa zasesibhakabhakeni . Xa ulinganisa ukuphakama kwemizimba yasezulwini, ukubonwa kwe-sextant ngesandla, vumela ityhubhu ye-telescope ukuba igcine inqanaba kwaye ilinganiswe ngumbono wesibuko se-horizon yasezulwini njengoko ibonwa kwi-telescope; kwangelo xesha linye ukulawula imisebenzi yezixhobo , ukwenza iteleskopu yeenkwenkwezi ekwindla ibone elundini . Esi sisizathu semfuno yokwenziwa kwesipili seglasi ebonisa isiqingatha seglasi.
