The Sino-Indian border is one of the highest in the world and a sensitive zone between two Asian powers. Here, there are frequent frictions and confrontations between the Chinese and Indian armies, and sometimes even clashes. In order to protect its territory and sovereignty, China has deployed advanced surveillance and defense systems in the border areas, mainly including satellites and drones.
The satellite system is China's eye in the Sino-Indian border area and can monitor the movements and positions of Indian troops in real time. Satellites can capture "unknown persons" in the border area and promptly notify the nearby squadron posts for patrol and expulsion, effectively preventing the infiltration and encroachment of the Indian army. The advantages of satellite systems are wide coverage, fast information transmission, and are not affected by terrain and climate. After the Galwan Valley incident in 2020, China paid more attention to the construction and application of satellite systems, and invested more satellite resources to monitor the Sino-Indian border.
The unmanned aerial system is China's sharp blade in the Sino-Indian border area, which can conduct reconnaissance and strikes at high altitudes. UAVs can replace the border patrol tasks of some squadrons, reducing their burden and risks. The advantages of UAS are high flexibility, low cost, and not limited by personnel and equipment. China has made great progress in drone technology, and different types and sizes of drones can be used to adapt to different tasks and environments. China mainly uses large jet drones for high-altitude reconnaissance in the Sino-Indian border area, while retaining some small rotary-wing drones for low-altitude patrols.
Of course, China's surveillance and defense systems in the Sino-Indian border region do not rely solely on satellites and drones. China has also set up a number of unmanned radar stations in the border areas, which can monitor the movements of Indian missiles and warplanes and carry out early warning and countermeasures in a timely manner. These unmanned radar stations can operate stably for a long time at high altitudes, do not require personnel maintenance, and can also be remotely controlled. India's Eurasian Times once reported that China had established an unmanned radar station at an altitude of more than 5,000 meters, which caused India's fear and concern.
In addition to these high-tech equipment, China has also retained a certain amount of manpower patrols in the Sino-Indian border area, mainly to deal with some unexpected situations and to demonstrate China's determination and confidence. The life and work of the squadron in the border areas are very difficult, and they have to face various difficulties and challenges such as lack of oxygen on the plateau, low temperature and cold, complex terrain, and strong hostility. In order to ensure their physical and mental health, Chinese outposts in border areas are equipped with oxygen facilities, allowing them to receive oxygen regularly. The squadron is also equipped with a number of portable oxygen concentrators that allow them to move while on oxygen while patrolling.
China's surveillance and defense system in the Sino-Indian border area is an important part of China's national defense and an important means for China to maintain peace and stability. China has effectively prevented the infiltration and encroachment of Indian forces through high-tech means such as satellites and drones, while also retaining some manpower patrols to demonstrate deterrence and self-confidence. China's goal in the Sino-Indian border area is to safeguard its territory and sovereignty, and not to seek conflict and confrontation, but also to make concessions and compromises. China hopes to coexist peacefully and develop together with India, but it will not give up its own interests and dignity.
