　　car Thieves could Be Stopped Remotely

　　Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in a nasty surprise. The car is fitted with a remote immobilizer and a radio signal from a control center miles away will ensure that once the thief switches the engine 1 off , he will not be able to start it again.

　　For now, such devices 2 are only available for fleets of trucks and specialist vehicles used on construction sites. But remote immobilization technology could soon start to trickle down to ordinary cars, and 3 should be available to ordinary cars in the uK 4 in two months.

　　The idea goes like this. A control box fitted to the carincorporates 5 a miniature cellphone, a microprocessor and memory, and a gPS satellite positioning receiver. 6 If the car is stolen, a coded cellphone signal will tell the unit to block the vehicle’s engine management system and prevent the engine 7 being restarted.

　　There are even plans for immobilizers 8 that shut down vehicles on the move, though there are fears over the safety implications of such a system.

　　In the uK. an array of technical fixes is already making 9 life harder for car thieves. “The pattern of vehicles crime has changed,” says martyn Randall of Thatcham, a security research organization based in Berkshire that is funded in part 10 by the motor insurance industry.

　　He says it would only take him a few minutes to 11 teach a novice how to steal a car, using a bare minimum of tools. But only if the car is more than 10 years old.

　　modern cars are a far tougher proposition, as their engine managementputer will not 12 allow them to start unless they receive a unique ID code beamed out by the ignition key. In the uK, technologies like this 13 have helped achieve a 31 per cent drop in vehicle-related crime since 1997.

　　But determined criminals are still managing to find other ways to steal cars. often by getting hold of the owner’s keys in a burglary. In 2000, 12 per cent of vehicles stolen in the uK were taken using the owner’s keys double the previous year’s figure.

　　Remote-controlled immobilization system would 14 put a major new obstacle in the criminal’s way by making such thefts pointless. A group that includes Thatcham, the police, insurancepanies and security technology firms have developed standards for a system that could go on the market sooner than the 15 customer expects.

　　远程制止偷车贼 (c)

　　超速驾驶在偷来的汽车里，偷车贼以为自己大获全胜。但是他马上就会又惊又恼。车上已经被装了远程制动装置，一个几英里以外的控制中心发来的无线信号将确保盗贼一旦启动引擎，他就不能再次发动汽车了。

　　目前，这种装置只用于卡车队或者用于建筑工地的特殊车辆上。但是远程制动技术很快就会逐步应用到普通汽车上。并且应该在两个月之内用在英国的普通汽车上。

　　计划是这样的。把一个集合有微型无绳电话，微量处理器，存储器以及全球定位系统的卫星接收器的控制合子安装在汽车上。如果汽车被盗，一个被编码的无绳电话信号就会告诉这个装置停止车辆引擎控制系统来阻止引擎再次被启动。

　　甚至还有一些人主张计划将制动装置装在运行着的车辆上，可是这一来人们就会担心这个系统的安全性。

　　在英国，一系列的技术装置已经让盗车贼步履维艰了。玛丁兰多来自位于贝克郡的一个由汽车保险工业投资成立的名为撒策姆的安全研究机构。他说：“车辆盗窃的手法已经有所改变。”他还声称只要是10年以上的汽车，他就能用几样的简单的工具有几分钟之内教会一个新手怎样的偷车。

　　现代车却远没有这么简单，因为它们的引擎管理计算机装置只有接收到一个独一无二的由点火钥匙发送过来的身份密份才可以启动汽车。自1997年以来，在英国，技术人员已经利用此项技术帮助减少了31%的涉及车辆犯罪案。

　　但是不死心的盗贼们却还在一直想方设法偷车。例如很多时候，他们在夜里盗走主人的汽车钥匙进而偷车。在2000年，英国21%的车辆被盗案是由于主人的钥匙被盗，这个数字比前一年增长了1倍。

　　远程控制的制动系统给盗贼设置了一个全新的障碍。包括撒策姆，公安部门，保险公司以及安全技术公司的这样一个群体已经为体系开发出了一个标准，将比顾客所预期的更早地被很快推广到市场上。 www.gaofen123.com

　　china to help Europe Develop gPS Rival

　　china is to contribute to a new global satellite navigation system being developed by European nations. The galileo satellite system 1 will offer a more accurate civilian alternative to the global Positioning System(gPS). operated by the uS military. china will provided 230m Euros (uSD 259m) in 2 funding and will cooperate with technical, manufacturing and market development. “china will help galileo to 3 be the major world infrastructure for the growing market for location services,” said Loyola de Palacio, Eu transportmissioner.

　　A new center that will coordinate co-operation was also announced 4 by the Europeanmission, the European Space Agency (ESA) and the chinese ministry of Science and Technology not long 5 ago .The china-Europe global Navigation Satellite System Technical Training and cooperation center will be 6 located at Beijing university. china has a substantial satellite launch industry and could potentially help the galileo satellites.

　　The uS has claimed that galileo could interfere 7 with the uS ability to downgrade the gPS service during military conflicts. European officials say this is unfounded and counter that uS opposition 8 is due to themercial challenge galileo would present to gPS. galileo will be precise to within a meter, while civilian gPS service is accurate to around 10 meters.

　　The galileo satellite constellation will 9 consist of 27 operational and three reserve satellites orbiting the Earth at an altitude of 23, 600 km. The satellites will be strung along three medium-Earth orbits at 56 degrees inclination to the equator and will provide global coverage. The system should be operational by 2009 and the entire project is expected to 10 cost around 3.2 billion Euros(uSD 3.6 billion).

　　The Europeanmission has said galileo will primarily be used for transportation technology, scientific research, land management and disaster monitoring.

　　galileo will provide two signals; a standard civilian one and an encrypted, wide-band signal 11 called the Public Regulated Service (PRS). This second signal is designed to withstand localized jamming and will be used by police and military services in Europe. Europeanmission __12_officials_ have said china will not be given access to the PRS.

　　The first galileo satellite is scheduled to launch late in 2004, clocks on board the 13_satellite_ will be synchronized through 20 ground sensors stations, twomand centers and 15 uplink stations.

　　Receivers on the ground will use time signals from the satellites to precisely calculate their 14 location . A “search and rescue” function will also 15 let distress signals be relayed through the constellation of satellites.

　　中国帮助欧洲发展全球定位系统的竞争 (B)

　　中国要捐助欧洲国家正在开发的全新的全球卫星定位系统。伽利略人造卫星系统将提供了一个较美国军事机构使用的全球定位系统更为精确的民用系统。中国将提供两亿三千万欧元(两亿伍千九百万美元)的资金，并且协助技术、制造以及市场拓展的开发。欧洲交通委员罗瑶拉德帕若索说：“中国将帮助伽利略(人造卫星)成为成长中的定位服务市场的主要世界基础设施。”

　　不久前，欧洲贸易委员会、欧洲航天局和中国科技部还宣称将建立一个新的中心来协助合作。中国——欧洲全球定位卫星系统技术培训和合作中心将设在北京大学。中国具有一个非常有实力的卫星发射工业。有可能帮助发射伽利略卫星。

　　美国声称伽利略会在军事斗争中干扰美国的能力并消减全球定位系统的使用。欧洲官员称这种说法无事实根据，并对美国所谓的伽利略(人造卫星)会对全球定位系统的商业上构成挑战的说法持反对意见。伽利略(人造卫星)将精确到一米，而民用全球定位服务只精确到10米。

　　伽利略人造卫星群由27个运用卫星和3个储备卫星构成，并在地球表面23 600千米的高度运行。卫星将与三个中等地球轨道并排在与赤道56度的倾斜角度上运行，并且可以覆盖全球。这个系统将在2009年启动，整个项目将耗资32亿欧元(36亿美元)。

　　欧洲贸易委员会说伽利略(人造卫星)最初将被用于交通技术、科学研究、陆地管理和自然灾害监控两种信号：一种是标准民用信号，另一种是公共调控服务系统加密信号。第二种信号是为抵抗地方交通堵塞而设计的，将被用于欧洲公安和军事事业。欧洲贸易委员会官员说中国将无权使用公共调控服务系统。

　　第一个伽利略人造卫星将在2004年底发射。这架卫星上的钟表将与20个地面感应站、2个指挥中心和15个上行站时间同步。

　　地面的接收器将利用卫星上的时间信号准确地计算出它们的方位。“搜索救援”功能也会通过卫星群传递遇难信号。

　　crashed cars to Text message for Help

　　There is no good place to have a car crash—but some places are worse than others. In a foreign country, for instance, 1 trying to explain via cellphone that you are upside down in a ditch when you cannot speak the local language can fatally delay the arrival of the emergency services.
