Suntsu品牌SGO12S系列GPS振荡器保持精确计时
Preserve Accurate Timing with Suntsu’s Upgraded GPS Disciplined Oscillator SGO12S Series
Suntsu released the first version of our GPS Disciplined Oscillator (GPSDO), the SGO10S. Now, we’re happy to say we’ve been working on a new GPSDO to help you build better products. A GPSDO, also called a GPS clock, is made up of a high-stability oscillator and a GPS receiver. These devices work by having the output of the oscillator controlled, or steered, through a tracking loop according to the GPS receiver or GNSS satellite signal.GPS Disciplined Oscillator (GPSDO), the SGO10S
The combination of a GPS receiver and the oscillator allows both short- and long-term stability for the device, making them one of the most accurate and trusted sources of timing. Because of this, GPS clocks are used in various network and satellite systems. Other applications they are good for include functioning as the basis for Coordinated Universal Time (UTC), synchronization to wireless base stations, PNT such as passive radar, critical infrastructure, and Cube and LEO Satellite Communications. After working to upgrade electrical performance and reduce the package size to meet market demands, Suntsu is proud to announce the next GPS Disciplined OCXO series, SGO12S, to our product line. Because we have improved phase noise performance and frequency stability over operating temperature without GPS lock, our upgraded GPSDO can be used for military communication equipment.
Suntsu’s SGO12S includes an internal GNSS receiver with 1PPS output compatible with GPS/QZSS L1 C/A, GLONASS L10F, BeiDou B1 SBAS L1, WAAS, EGNOS, MSAS, GAGAN, and Galileo applications. This oscillator is also connected to an external antenna via a SMA connector which can maintain a 1PPS signal with a holdover of 1.5µs for a 24-hour period if GNSS signals fail. It’s important to note that a reliable OCXO is necessary to ensure that even when signals are lost, accurate timing is preserved.
Suntsu品牌SGO12S系列GPS振荡器保持精确计时
使用Suntsu升级的GPS专业振荡器SGO12S系列保持精确计时
Suntsu松图晶振发布了第一个版本的GPS纪律振荡器(GPSDO),SGO10S。现在,我们很高兴地说,我们正在开发一个新的GPSDO来帮助您构建更好的产品。GPSDO也称为GPS时钟,由高稳定性振荡器和GPS接收器组成。这些设备的工作原理是根据GPS接收器或GNSS卫星信号,通过跟踪环路控制或操纵振荡器的输出。
GPS接收器和振荡器的结合使设备具有短期和长期稳定性,使其成为最精确和最可靠的时间源之一。因此,GPS时钟被用于各种网络和卫星系统。它们擅长的其他应用包括用作协调世界时(UTC)的基础、与无线基站同步、PNT(如无源雷达)、关键基础设施以及Cube和LEO卫星通信。在努力提升电气性能和缩小封装尺寸以满足市场需求后,Suntsu自豪地宣布我们产品线的下一代GPS规范OCXO晶振系列SGO12S。由于我们在没有GPS锁定的情况下改善了工作温度范围内的相位噪声性能和频率稳定性,因此升级后的GPSDO可用于军事通信设备。
Suntsu的SGO12S有源晶体包括一个内置GNSS接收器,1PPS输出,兼容GPS/QZSS L1 C/A、GLONASS L10F、北斗B1 SBAS L1、WAAS、EGNOS、MSAS、GAGAN和伽利略应用。该振荡器还通过SMA连接器连接到外部天线,如果GNSS信号失败,该连接器可以在24小时内保持1PPS信号,保持时间为1.5 s。需要注意的是,可靠的OCXO是必要的,以确保即使信号丢失,也能保持准确的时序。
