GNSS yolondola kwambiri

Gawo la nthawi yolondola kwambiri ya GNSS lonse lomwe lili ndi ma frequency ambiri

UT986 ndi mbadwo watsopano wa GNSS system multi-frequency, high-precision timing module yopangidwa payokha ndi Hexinxingtong. Module iyi imagwirizanitsa zosefera ndi ma linear amplifier, ndipo ili ndi mawonekedwe abwino a ma radio frequency ndi mphamvu zoletsa kusokoneza. Imagwirizanitsa ukadaulo wosinthika wotsutsana ndi kusokoneza ndi ukadaulo woletsa njira zambiri mkati, imathandizira kuzindikira kusokoneza ndi kuzindikira chinyengo, ndikuwonetsetsa kuti module iyi ikhoza kugwirabe ntchito m'malo ovuta amagetsi. Itha kupereka magwiridwe antchito abwino. Module iyi ikhoza kupereka kulondola kwa PPS ya nanosecond, kuthandizira nthawi yokhazikika, nthawi yodziyimira payokha, komanso nthawi yoyika, ndipo ikhoza kutsimikizirabe kulondola kwa nthawi m'malo ovuta a chizindikiro.

Zinthu Zofunika Kwambiri

2018-07-16

Kutengera m'badwo waposachedwa wa NebulasIV radio frequency baseband ndi high-precision integrated GNSS SoC chip

2018-07-16

Gawo latsopano la GNSS lomwe limagwiritsa ntchito ma frequency ambiri komanso nthawi yolondola kwambiri, lothandizira ma satellite a Beidou-3

2018-07-16

Kulondola kwa PPS pamlingo wa Nanosecond, komwe kumathandizira kuwonetsa kulondola kwa nthawi

2018-07-16

Mphamvu yabwino kwambiri yoletsa kusokonezedwa, njira yodziyimira payokha ya ma radio frequency, mphamvu yamphamvu yoletsa kusokonezedwa pakati pa ma frequency point

2018-07-16

Imathandizira kuzindikira kusokoneza ndi kuzindikira zachinyengo

2018-07-16

Thandizani nthawi ya nyenyezi imodzi ndi kutsegulidwa kwa siteshoni ya nyenyezi imodzi
