Adequate Utilization of GPS Resources to Promote the Development of China's Aviation Industry,
Abstract
After going through numberless calamities, setbacks, and losses from delays, the GPS (global positioning system) project, which lasted 20 years, finally announced the completion of deployment of the GPS satellite constellation which includes 24 satellites, following the sending of the last GPS satellite into orbit by the U.S. in the middle ten days of April 1993. GPS is one of the biggest developments in the field of aviation and space navigation/monitoring technology since the introduction of radio navigation 50 years ago. The impact of GPS on aviation is particularly profound. The reason is that, due to its success, it allows us, for the first time in history, to achieve a basic system which is capable of guiding all flight phases. 1993 was the first year that the GPS aviation market (including aircraft and airfields) really took off. The reason was that the whole satellite constellation had gone into operation, creating the conditions for aviation applications associated with high precision and global coverage. In recent years, internationally, global navigation satellite system (GNSS), using GPS as a foundation, as well as future aerial navigation system (FANS), using GNSS as a foundation, have come forward one after the other. Both of these are important applications of GPS in aviation. Obviously, the appearance of new technology will bring important benefits for aviation circles. However, it also presents new challenges. In order to evaluate these very promising new technologies using a realistic attitude, let us begin from investigating GPS development directions and application prospects, combining China's national situation, to seek out the work which we should do and are capable of doing, in expectation of making better use of GPS in order to promote the development of China's aviation industry.
