推进欧盟-亚洲卫星导航产业合作

航空 Aviation

由于卫星导航系统覆盖全球,并能够飞行的所有阶段提供同质的导航服务,其也能够在航空业发挥巨大作用。

Aviation can be significantly benefited from satellite navigation signals since they are globally available and enable a uniform quality of navigation throughout all phases of flight.

一直以来,航空都依赖于机场附近昂贵的地面广播导航系统,如着陆时以来仪表着陆系统(ILS)。EGNOS便旨在通过其生命安全服务满足安全着陆的需求。

Traditionally aviation relies on costly ground radio navigation systems near airports such as ILS (Instrument Landingplane landing System) for landing operations. EGNOS has actually been designed to answer aviation needs for secured landing approaches with the EGNOS Safety of Life service.

这一服务可以确保接收器给出的位置在特定范围之内,同时在出现故障时它将在6秒内向飞行员发送警告信息。因此,它可以用于飞行导航,在没有安装ILS的机场,它也可以辅助进行IFR(仪表飞行规则)类似的操作。

This service guarantees the position given by the receiver to be inside certain boundaries and encompasses an integrity function which consists in a warning message sent to the pilot within 6 seconds in case of malfunction. It can therefore be used for en-route navigation and allows for IFR-like (Instrument flight rules) operation in non ILS equipped airports.

通过降低接近角、改进侧向导航,EGNOS或许将提高机场客容量,也使昂贵的地面导航系统不再必要。

By reducing the angle of approach and bringing a better lateral guidance, EGNOS may increase airports' capacity and avoids the installation of expensive land based navigation aids.

即便在洲际飞航中,飞机也能够使用这一技术,因为EGNOS同美国广域扩充系统(US WAAS)、日本多功能卫星增强系统(MSAS)以及即将投入使用的印度境地轨道增强系统(GAGAN)等其他星基增强系统(SBAS)具有完全互操作性。虽然目前EGNOS规模较小(2010年,已安装的GNSSS设备仅有约9万台),但是欧洲的航空业对于欧洲整个私营部门的生产力具有非常大的影响力。

Aircrafts can rely on this technology even for intercontinental journeys, as EGNOS is completely interoperable with other Satellite Based Augmentation Systems (SBAS) such as the US WAAS, the Japanese MSAS or the forthcoming Indian GAGAN. Despite its relative small size with around 90 000 GNSS units shipped in 2010, the aviation sector has a significant productivity impact on the whole European private sector.
