Suntsu松圖晶振公司發(fā)布了第一款GPS紀(jì)律振蕩器（GPS do）sgo 10s。現(xiàn)在，我們很高興地說，我們一直在開發(fā)一個(gè)新的GPSDO，以幫助您構(gòu)建更好的產(chǎn)品。GPSDO也稱為GPS時(shí)鐘，由高穩(wěn)定性石英晶體振蕩器和GPS接收器組成。這些設(shè)備的工作原理是根據(jù)GPS接收器或GNSS衛(wèi)星信號(hào)通過跟蹤環(huán)路控制或操縱振蕩器的輸出。

GPS接收器和振蕩器的結(jié)合使設(shè)備具有短期和長期穩(wěn)定性，使其成為最精確和最可靠的時(shí)間源之一。因此，GPS時(shí)鐘被用于各種網(wǎng)絡(luò)和衛(wèi)星系統(tǒng)。它們擅長的其他應(yīng)用包括作為協(xié)調(diào)世界時(shí)（UTC）的基礎(chǔ)、與無線基站同步、PNT（如無源雷達(dá)）、關(guān)鍵基礎(chǔ)設(shè)施以及Cube和LEO衛(wèi)星通信。在努力提升電氣性能并縮小封裝尺寸以滿足市場(chǎng)需求后，Suntsu自豪地宣布我們的產(chǎn)品線將推出下一代GPS標(biāo)準(zhǔn)OCXO系列SGO12S石英晶振。由于我們?cè)跊]有GPS鎖定的情況下改善了工作溫度范圍內(nèi)的相位噪聲性能和頻率穩(wěn)定性，因此升級(jí)后的GPSDO可用于軍事通信設(shè)備。
Suntsu晶振SGO12S包括一個(gè)內(nèi)部GNSS接收器，具有1PPS輸出，與GPS/QZSS L1 C/A、GLONASS L10F、北斗B1 SBAS L1、WAAS、EGNOS、MSAS、GAGAN和伽利略應(yīng)用程序兼容。該振蕩器還通過SMA連接器連接到外部天線，如果GNSS信號(hào)出現(xiàn)故障，該連接器可以在24小時(shí)內(nèi)保持1PPS信號(hào)，保持時(shí)間為1.5 s。值得注意的是，可靠的OCXO是必要的，以確保即使在信號(hào)丟失時(shí)也能保持準(zhǔn)確的時(shí)間。

Suntsu振蕩器SGO12S-10.000M系列保持精確計(jì)時(shí)
we 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.
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.
