GT-350 GNSS衛星時鐘接收器
簡述
GT-350衛星時鐘接收器(GNSS Time Transfer Receiver)是為了提供高精度的時間基準而設置。經GPS接收器處理後時間信號以RS-232傳送至母鐘,子鐘或PC,其傳送資料含年、月、日、時、分及秒,每秒傳送一次。
特色
- 高靈敏度及多星系接收能力
- 支持SBAS,包括WAAS/EGNOS/MSAS
- 符合NMEA-0183協議
- IPX7等級防水結構
- 電纜長度和連接器可定制
Product description產品介紹
GT-350衛星時鐘接收器(GNSS Time Transfer Receiver)是為了提供高精度的時間基準而設置。全球衛星定位系統是由地面工作站以高於10-8的精度向衛星發送信號並傳送至全球各地衛星。經GPS接收器處理後時間信號以RS-232傳送至母鐘,子鐘或PC,其傳送資料含年、月、日、時、分及秒,每秒傳送一次。
GT-350具特殊造型及100%防水設計,使用Ublox M10晶片組加上內建的主動型陶瓷天線讓定位更為精準。
