AccuBeat晶振用于空間解決方案的原子鐘，太空任務(wù)和深空探索計(jì)劃依賴于高精度原子鐘，AccuBeat很自豪能夠被選中為歐洲航天局(ESA) 的JUICE（木星冰月探測(cè)器）任務(wù)開(kāi)發(fā)和生產(chǎn)超穩(wěn)定振蕩器(USO) 。
AccuBeat用于深空的空間合格超穩(wěn)定振蕩器 (USO) 解決方案將作為任務(wù)中計(jì)時(shí)的中心來(lái)源，并將成為由以色列魏茨曼研究所的Yohai Kaspi教授和Eli Galanti博士領(lǐng)導(dǎo)的無(wú)線電科學(xué)掩星實(shí)驗(yàn)的一部分與羅馬La-Sapienza大學(xué)的Luciano Iess教授合作。正如Kaspi教授在附信中提到的那樣贊賞 “基于AccuBeat開(kāi)發(fā)的USO的出色穩(wěn)定性，我們期望獲得前所未有的科學(xué)回報(bào)，這使我們能夠首次以極高的準(zhǔn)確度表征木星大氣的垂直結(jié)構(gòu)，降至2 bar的水平。” 計(jì)劃中的實(shí)驗(yàn)將通過(guò)跟蹤穿過(guò)大氣層的無(wú)線電波的相位變化來(lái)探測(cè)木星的大氣層，同時(shí)航天器使用AccuBeat的超高穩(wěn)定性頻率源傳輸?shù)降亍?br /> AccuBeat的USO是一種高穩(wěn)定性石英晶體振蕩器，采用高Q晶體諧振器和100µ開(kāi)爾文范圍內(nèi)的高溫穩(wěn)定性。由AccuBeat設(shè)計(jì)的USO在1到1000秒的積分常數(shù)下，其艾倫偏差明顯優(yōu)于5E-13的要求規(guī)格，使其成為同類(lèi)中最穩(wěn)定的振蕩器，專(zhuān)為深空探索而設(shè)計(jì)。AccuBeat的USO旨在滿足此規(guī)范，同時(shí)經(jīng)受苛刻的EMC影響和木星周?chē)膼毫迎h(huán)境，某些內(nèi)部組件的輻射水平高達(dá)100kRad。

JUICE是歐洲航天局(ESA) 的旗艦項(xiàng)目，2022年5月，該航天器將啟程前往木星，行程近6億公里，預(yù)計(jì)2030年到達(dá)木星。三年半的時(shí)間里，JUICE將在 AccuBeat為深空探索設(shè)計(jì)的USO的幫助下環(huán)繞這顆巨大的行星，探索其動(dòng)蕩的大氣層、巨大的磁層和一組脆弱的暗環(huán)，并研究其三個(gè)最大的冰衛(wèi)星——木衛(wèi)二、木衛(wèi)三和卡利斯托。JUICE項(xiàng)目經(jīng)理 Vincent Poinsignon 說(shuō)：“我們的目標(biāo)是調(diào)查這些冰殼下是否存在液態(tài)海洋，這些海洋可能含有有機(jī)成分甚至生命。”
