外国专家:北斗已超越欧盟、俄罗斯卫星导航系统

2017-09-20 10:33:54   中国青年网

2015年3月,我国北斗全球系统首颗试验卫星成功发射。在轨测试表明,该团队研制的卫星载荷,其抗干扰能力在原基础上又提高了100倍,采用数字光纤技术的试验注入站系统,信号时延稳定性比第一代系统提高两倍,时频信号远距离传输能力提高了60多倍。

如今,这个团队已成为北斗卫星导航定位系统总体设计、关键技术攻关和工程建设的主要依托单位之一,也是国内唯一同时承担系统核心体制、卫星关键载荷、运控主体、测试设备研制任务的单位。

把成果实时转化为战斗力

在边防巡逻、抢险救灾、海上搜救的镜头中,经常能看到执勤和救援人员手持北斗用户机,报告自己的准确位置。

这款具有定位、短报文通信功能的便携式北斗用户机,就是该校卫星导航技术创新团队将科研成果转化战斗力的成功案例。

用自主创新成果服务战斗力建设,始终是该团队的不懈追求。他们一边着力突破核心关键技术,一边瞄准应用需求,不断推动科研成果向战斗力转化。

导弹要提高打击精度,需要卫星导航提供帮助。那么炮弹呢?由于炮弹体积小,难以容纳导航设备,曾被人认为是异想天开,不可能实现。

要给火炮装上“眼睛”,就必须研制极小的导航接收机。这个团队经过刻苦攻关,创造性地研制出一种只有硬币大小的“炮弹专用北斗导航接收机”。这项成果一经应用,随即创造出我军火炮射击命中率的新纪录。

2016年5月,工程车辆精准导航测向系统由团队研制成功。这套由手机大小的主机和两个光盘大小的天线组成的系统,能有效提高车辆、船舶和无人机平台的精准定位与测向,并可帮助无人机完成自主起降、固定高度自主巡航和空中悬停自主转向等高难度动作,极大提高了装备战斗力。

“部队有什么需求,我们就研制什么装备。”团队教授孙广富介绍,目前,用于各类飞机、舰船、车辆、导弹等武器装备的某型核心导航芯片,70%由团队研制生产,并全部实现了自主可控。

努力实现世界第一

2015年,王飞雪等专家受邀赴俄罗斯参加莫斯科导航论坛。国际卫星导航界有专家感叹:中国北斗已超越欧盟的“伽利略”和俄罗斯的“格洛纳斯”了!

在王飞雪心中,努力实现世界第一,才是他和团队追求的目标。他告诉记者:正在建设中的“北斗三号”全球导航系统,2020年实现全球覆盖后,部分性能将有望领先于GPS。

为了实现这一目标,自2014年以来,团队在北斗全球系统体制设计、信号设计及实现、星上载荷研制、地面运控及测试评估设备等方面,承担了数十项关键技术攻关和核心装备研制任务。

作为北斗工程重大专项导航技术专家组的组长单位,这个团队还全面参与国家综合导航定位授时体系、国家时频体系、时空基准等专项工作。

截至去年,团队出色完成了北斗三号“全体制、全系统、全链路”30余项关键技术攻关任务。团队研究员陈华明告诉记者,为了早日实现北斗全球覆盖目标,团队目前承担着新一代北斗核心导航信号设计、30颗卫星的数百台单机模块、数千台(套)地面站关键设备的研制任务。

攻关无尽期,梦想在前方。每次采访这个团队,眼前的一幕都会让记者赞叹:实验室里,一排排机柜上的显示灯急速闪烁,键盘敲击声响成一片,宛如千军万马在呐喊、冲锋……
