Spacecraft flew hundreds of thousands to hundreds of millions of kilometers from the earth, injecting speed when the size and direction of a slight error, arrived at target planets will appear large deviation error, for example, when Mars probe injecting speed 1 m/s speed (about one over ten thousand), arrived at Mars, about 100000 km distance deviation. Therefore, precise control and navigation must be carried out during the long flight. Flying to the moon is usually controlled by the orbital control system of the ground and space probe (see orbit control). Interplanetary flight distances, radio signal transmission time is long, the real-time remote control, can't so planets and interplanetary spacecraft orbit control system shall have the ability of autonomous navigation (see interstellar travel navigation and control). The United States, for example, "pirates" spacecraft in space flight of more than eight hundred million km, for 11 months of 2000 times of autonomous orbit adjustment, the final surface to achieve a soft landing on Mars, placement accuracy up to 50 km. In addition, in order to ensure the accuracy of the orbit control engine, the communication antenna is always aimed at the earth, and other systems work normally, and the detector has the autonomous attitude control ability
Yes you read that right. The higher the car's horsepower, the faster it might drive, the much more likely it will be driven at elevated speeds, enhancing the likelihood of any sort of accident therefore the likelihood of replacing and already expensive car. (Most cars with high horsepower, with 500 hp and above, cost inside hundreds of thousands of dollars.) When asking exactly what is the most high-priced car to insure, maintain the horsepower in your mind.
If you're worried such a program might do with that privilege, like sending error reports, submitting user data or automatically updating itself, it is possible to block it with outbound rules from the firewall's advanced settings. Once a blocking rule has become established, it remains one of several configured rules, so it is possible to quickly enable or disable it to regulate the program's access.
China's first production country, gradually developed into the world tire industry has been built all kinds of complete series of products of complete industrial system, and obtain a series of original innovation characteristics of international frontier technology progress. China's heavy-duty meridian has reached the advanced level of the world through high speed and high load test. The radial tyre of the sedan has achieved no inner tube, wide section, flat and high speed. The safety, energy conservation and environmental tyre of the international trend have been steadily pushed into the international market and gained recognition
