China successfully launched the Goffin 14 satellite. What is the main purpose of this satellite?

Xinhua News Agency, Xichang, 65438+February 6th (Zhu) 65438+At 0: 58 on February 6th, China successfully put the 14th satellite into the scheduled orbit in xichang satellite launch center, and the launch was a complete success.

First of all, the successful launch of Gao Fen Satellite deserves our celebration, so let me tell you the purpose of Gao Fen Satellite 14. Gao Fen 14 satellite is an optical stereo mapping satellite. Just from its explanation, we know that it has a wide range of uses. Satellite mapping is very common in our life. For example, the navigation software in our mobile phone has the participation of satellite mapping function. The satellite sends pictures to the ground through satellite photography technology, and the staff uses the pictures as a virtual map according to a certain proportion after special calculation. This is the application of surveying and mapping satellites in people's daily travel.

2. Gao Fen 14 satellite is a high-resolution optical mapping satellite. It is reported that it can obtain high-definition stereoscopic images all over the world. I believe that if it is applied to the weather forecast, the weather forecast will become very accurate. This is a bit overqualified. In fact, its main purpose is to measure large-scale digital topographic maps and make digital elevation models, digital ground models and digital orthophoto maps. Large-scale digital topographic map is very convenient for the implementation of some large-scale projects, and Gao Fen-14 satellite has also strengthened China's national defense force and greatly helped China's military force.

3. Gao Fen 14 satellite has a wide range of uses, but its main function is to survey topography. Its successful launch will improve the field of mapping in China. With it, those places on the map that have not been fully explored will be refilled, and those areas with flat terrain suitable for people's lives will be discovered and developed. It can also monitor and track some illegal acts, which is more convenient for social security.
