测向仪（DF）可以被飞机或船舶用作导航辅助设备。

这是通过测量至少两个位置已知的发射机的方向（方位）来完成的。

当将来自每个发射器的测量方向绘制在地图上时，两条绘制线的交点给出携带

DF的飞机或船的位置。

这种技术使用两个或多个已知位置发射机的方向，称为三角测量。

1. 2016年测向仪的全球市场规模为90.03 K美元，预计到2022年将达到99.39 K美元，复合年增长率为1.66％。对测向仪的需求主要受到搜救，船舶交通服务，空中交通管制等领域的推动。搜救是市场的主要增长催化剂。

2.生产测向仪的主要地区是美国，德国和日本，占总产值的80％以上。测向仪产品需求处于一定空间，主要消费国为中等发达国家和发达国家

4.近几年来，国内厂家开发的新型测向仪总数有限。这表明在中国开发新产品的努力还不够，但也表明国内测向仪的配置空间还需要扩大。与进口测向仪相比仍有很大差距。

5.随着国内外高端产品的大量需求，许多企业开始进入高端领域。目前，中国测向仪行业需要过渡到高端产品，这个行业在中国仍然有相当的发展前景。

A direction finder (DF) can be used by an aircraft or ship as a navigational aid. This is accomplished by measuring the direction (bearing) of at least two transmitters whose locations are already known. When the measured directions from each transmitter are plotted on a map, the intersection of the two plotted lines gives the location of the aircraft or ship carrying the DF. This technique, using the directions to two or more transmitters of known location, is called triangulation.

1. The global market scale of direction finder was 90.03 K USD in 2016. It is expected to reach 99.39 K USD by 2022, with the CAGR of 1.66%. Demand for Direction Finder has mainly been driven by field of search and rescue, vessel traffic service, air traffic control, etc. Search and rescue are the main growth catalysts for the market.

2. The Major regions to produce direction finder are United States, Germany and Japan, which accounting for more than 80 % of production value in total. Direction Finder product demand is in a certain space, and the main consumer countries are moderately developed countries and developed countries

4. In the last few years, the total number of new type of direction finder developed by domestic manufacturers is limited. This shows that the efforts to develop new product in China is not enough, but also shows that the allocation space of domestic direction finder still need to expand. There is still a big gap compared with the imported direction finder.

5. As large demand of high-end products at home and abroad, many companies began to enter the field of high-end. Currently, the Chinese direction finder industry needs to transit to high-end products, this industry still has considerable development prospects in China.
