Khoom Taw Qhia

Lub kav hlau txais xov no muaj cov yam ntxwv hauv qab no:
Txhawb kev pab them nqi ntawm GPS L1 zaus band thiab GLONASS L1 zaus band, thiab yog tsim nyog rau tau txais satellite signals nyob rau hauv ob zaus bands.
Lub tsev kav hlau txais xov muaj qhov nce siab thiab muaj peev xwm tau txais cov cim tsis muaj zog.Cov qauv beam yog dav thiab tuaj yeem tau txais ntau yam ntawm cov teeb liab.Nws muaj peev xwm txais tau lub teeb liab zoo ntawm qhov siab qis thiab tuaj yeem tau txais satellite teeb liab ntawm qhov siab qis.
Kev sib koom ua ke pub tsim tau txais los xyuas kom meej tias theem nruab nrab ntawm lub kav hlau txais xov coincides nrog lub chaw geometric los txhim kho qhov chaw raug.
Nws tuaj yeem siv nrog ntau yam khoom siv satellite navigation davhlau ya nyob twg los muab cov neeg siv nrog cov kev pabcuam siab ua haujlwm.
