GPS L1 L5 & Beidou B1 Ib Leeg Pub stacked thaj kav hlau txais xov
Khoom Taw Qhia
Cov kav hlau txais xov sib dhos yog ib hom kav hlau txais xov uas nquag siv hauv kev siv GPS.Nws yog tsim los ua haujlwm ntawm L1 thiab L5 zaus bands, uas yog cov zaus siv los ntawm GPS satellites rau qhov chaw thiab kev taw qhia.Tsis tas li ntawd, nws yog sib xws nrog IRNSS (Indian Regional Navigation Satellite System) zaus bands.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov kav hlau txais xov sib txuas yog nws qhov loj me, ntsuas tsuas yog 25 * 25 * 8.16 hli.Qhov no ua rau nws tsim nyog rau kev koom ua ke rau hauv cov khoom siv me me thiab cov cuab yeej siv tau yooj yim uas qhov chaw feem ntau txwv.Lwm qhov tseem ceeb ntawm lub kav hlau txais xov no yog nws qhov qis axial piv.
Cov ntawv thov raug suav nrog:
- RTK
- Hnav tau
- Kev thauj mus los
- Kev ua liaj ua teb
- Kev taw qhia
- Kev ruaj ntseg
- Autonomous Tsheb
