当前，我国疫情防控形势持续向好，防控重点向“外防输入、内防反弹”转变，同时各地加速复产复工，生产生活秩序正在逐步恢复，我国航空装备企业正在加速重返全球航空装备产业链。

Major aircraft OEMs, mainly in the commercial aircraft industry, have emphasized on improving the overall air travel experience, including customer safety and reliability. In addition, fuel efficiency has become an important factor in determining the airline’s choice of aircraft during the purchase decision-making process. In this regard, the focus on the air management systems has become very crucial over the last two decades. Currently, the suppliers of commercial aircraft air management systems are working closely with the aircraft OEMs for the developments of advanced systems, to address the dynamic market requirements. This may also help them to remain as a preferred choice in the market. The aircraft and related subsystems industries are technology driven. The replacement of conventional sensors with the latest sensors, which yield better and accurate results, and the development of robust heat exchangers are helping the production of more efficient air management systems. The introduction of no-bleed systems architecture in Boeing 787 Dreamliner initiated a revolution in the air management systems industry. This system offers better operational efficiencies due to the replacement of traditional pneumatic systems with electrical systems, providing advantage in terms of weight and lifecycle costs. The commercial aircraft industry is the largest procurer of the air management systems, due to a higher requirement for the system, compared to any other end-user industries. This is explained by the presence of larger passenger cabins in the commercial aircraft.

据北斗卫星导航官网报道，北斗系统最后一颗组网卫星已运抵西昌卫星发射中心，进入发射准备，并将择机发射，届时北斗全球星座的布局将全面建成。北斗三号实现全球组网后，其定位精度和授时精度将取得大幅提升，下游应用市场料将逐步打开并形成千亿级的市场需求。我们认为“北斗+”的商业模式将为产业链带来较好的发展机遇，重点推荐海格通信。
