雷声公司演示陆基版联合精密进近着陆系统(JPALS)******

原标题:雷声公司演示陆基版联合精密进近着陆系统(JPALS)

  [据GPS World网站2019年4月9日报道]雷声公司在亚利桑那州尤马海军陆战队航空站首次向美国空军、海军和海军陆战队演示了陆基远征版联合精密进近和着陆系统(JPALS)。这次概念验证活动表明,目前在各种气候条件下引导F-35B着舰的JPALS系统可以重新配置为机动版本,实现在各种机场条件下着陆。

JPALS是一种应用GPS的差分精密着舰系统,能够在各种气候,以及5级海况条件下引导飞机在航母和两栖攻击舰上着舰。JPALS采用加密抗干扰数据链与机载任务计算机软件、接收机硬件、一组GPS传感器、桅杆天线和舰载航空电子设备相连。

演示期间,F-35B飞行员使用机载JPALS系统与200海里外的远征版地面系统连接,之后,由系统引导飞行员在跑道指定的着陆点着陆。雷声公司情报、信息和服务业务副总裁说:“JPALS可以帮助任何固定翼或旋转翼飞机在全球崎岖、能见度低等恶劣环境的基地着陆。”

与传统的应用雷达引导着陆的系统不同,JPALS不发射雷达信号,从而大大提高了位置安全性。在多山地域和沙漠尘暴等雷达难以工作的条件下确保飞行员的安全。JPALS甚至可以帮助空军飞行员在零可见度和零云底高度条件下着陆。远征陆基版JPALS可以同时控制半径为20海里的多达50架飞机,可应用于应急行动,比如对抗新的威胁或帮助飞机提供人道主义救援,满足美空军在更为简朴、恶劣的基地实施飞行行动的需求。

陆基远征版JPALS系统可分装成五个运输箱,装载于小型运输车辆,由C-130运输,或者悬挂在重型运输直升机下。但系统最终配置可以根据各军种的需求决定。这种机动式陆基JPALS占地面积小,90分钟内即可完成安装投入运行。(中国电科20所 魏艳艳)

West Ham brush past Villa to make it closer at top, Leeds claim three vital points******

LONDON, Oct. 31 (Xinhua) -- West Ham United highlighted their excellent moment of form with a 4-1 win away to Aston Villa in the English Premier League on Sunday.。

The victory keeps them fourth in the table but draws them level on points with third place Manchester City and puts them just two behind Liverpool and five behind league leaders Chelsea.。

Defender Ben Johnson put West Ham ahead after just seven minutes when he cut inside and scored with a low shot and although Ollie Watkins drew Aston Villa level in the 34th minute, it was a false hope for the home side.。

Declan Rice deservedly put West Ham back ahead just four minutes later and Villa's task was made much harder when Ezil Konsa was sent off five minutes into the break.。

Playing with 10 men, the home side tired in the closing minutes allowing Pablo Fornals and Jarrod Bowen to add two more goals in the closing minutes.。

Leeds United claimed their second win of the season as Rodrigo's 60th minute shot, with the aid of an error from Norwich coach Tim Krul gave them a 2-1 win in Carrow Road.。

All of the goals came in a frantic four-minute spell with Raphinha putting Leeds in front on 56 minutes, before Andrew Omobamidele's header two minutes later gave Norwich hopes of their first triumph of the campaign.。

On Saturday, Chelsea won 3-0 away to Newcastle United, while Manchester City lost 2-0 at home to Crystal Palace and Liverpool were also held to a surprise 2-2 draw at home to Brighton. Enditem。

Sweden's Andersson elected as nation's first woman PM******

Sweden's parliament yesterday elected Social Democratic party leader and current Finance Minister Magdalena Andersson as the country's first woman prime minister, after she clinched a last-minute deal securing key support.。

Andersson will succeed outgoing Prime Minister Stefan Lofven after a total of 117 members of parliament voted for her, while 57 abstained, 174 voted against and one was absent.。

Under Sweden's system, a prime ministerial candidate does not need the support of a majority in parliament, they just need to not have a majority – or 175 votes – against them.。

The 54-year-old, who took over as leader of the Social Democrats earlier this month, reached a deal with the Left Party late on Tuesday to raise pensions in exchange for its backing in yesterday's vote.。

She had previously received the support of the Social Democrats' coalition partner the Greens, and the Centre Party.。

However, Andersson faced her first setback even before her election yesterday.。

The Centre Party announced that while it would not oppose Andersson in the vote for prime minister, it would withdraw its support for the government's budget to be voted on later yesterday, due to the concessions made to the Left.。

That means Andersson will in all likelihood have to govern with a budget presented by the opposition conservative Moderates, Christian Democrats and far-right Sweden Democrats.。

Andersson will formally take over her functions and present her government tomorrow.。

Stefan Lofven resigned on November 10 after seven years as prime minister in a widely expected move aimed at giving his successor time to prepare for the country's September 2022 general election.。
