Is a new type of ballastless track, with reinforced concrete slabs, and under the big board with emulsified asphalt cement mortar as the first adjustment layers (or overlay on a cushion of high molecular elastic material layer) consisting of orbit. This kind of track is suitable for stone roadbed or non - ballasted deck. The asphalt concrete bearing layer shall be installed on the soil foundation. This kind of track integrity is good, the line is stable, the maintenance workload is small, but the cost is high, the construction period is long. Japanese railways have been used in the Shinkansen
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
