Guohai Securities released a research report on April 8 stating that it gave Narei Radar (688522.SH) a purchase rating. The main reasons for the rating include: 1) the continuous release of weather and water radar tenders in Guangdong Province, with the first batch of 35 units; 2) building a low-altitude traffic management system is a prerequisite for large-scale low-altitude flight; the Civil Aviation Administration supports Shenzhen in building a low-altitude economy industry demonstration zone, and the “New Deal” for general aviation equipment promotes the development of the low-altitude economy industry; 3) Narui Radar's traditional main business is waiting to expand the company's new growth direction for the “low altitude economy” reserve technology.
