新华社北京８月２０日电（记者 林晖）中国气象局局长郑国光２０日宣布，我国第四颗业务型静止气象卫星风云二号Ｆ星正式交付。

    Beijing, aug. 20（Reporter LinHui）The China meteorological administration director zheng 20 announced，The fourth planet in our country YeWuXing static meteorological satellite of 2 F formally deliver the star。

    风云二号气象卫星是我国第一代静止气象卫星，其中Ｆ星是风云二号０３批工程的首发星，也是我国第四颗业务型静止气象卫星，于２０１２年１月１３日上午８时５６分在西昌卫星发射中心成功发射。

    The number two meteorological satellite is China's first generation of static meteorological satellite，The F star is the number two 03 batch of project starting star，China is the fourth planet YeWuXing static meteorological satellite，On January 13, 2012 at 8 in the morning 56 points in the xichang satellite launch center successful launch。

    风云二号Ｆ星设计寿命为４年。在０２批卫星成功经验的基础上，风云二号Ｆ星进一步提高了探测精度，同时具备对特定区域更加灵活的高频次观测能力。以台风预报为例，这一区域加密观测能力将使台风定位定强预报时间提前１０分钟，可为灾害预警和防灾减灾工作节省宝贵时间。

    The 2 F star design life for 4 years。In 02 batch of satellite based on the successful experience，The 2 F star further improve the detection precision，At the same time have a particular area of more flexible high frequency observation ability。To the typhoon forecast as an example，This area encryption observation ability will make the typhoon location fixed strong forecast time 10 minutes earlier，For disaster warning and disaster prevention and alleviation save valuable time。

    据了解，风云二号Ｆ星交付后，将接续风云二号０２批卫星业务，与目前在轨运行的Ｄ星和Ｅ星共同组网，进一步强化我国静止气象卫星“双星观测、在轨备份”的业务格局。

    It is understood，The 2 F star after delivery，We will continue the number two 02 batch of satellite business，And now orbiting the star of D and E star common network，Further strengthen our country still meteorological satellite“Binary observation、On-orbit backup”Business pattern。
