A New Perspective to Integrated Satellite Navigation Systems

In order to further expand and enhance the level of applications of satellite navigation, three new systems are proposed on the basis of successful application of existing satellite navigation systems: a two-way satellite communication and navigation system which is based on a two-way satellite communication transmission link, a satellite-assisted ground mobile communication and navigation system and an air–ground communication cooperation multi-system multi-mode positioning system. Key technologies for achieving breakthroughs and implementation of the three new systems are also described, including deep integration of navigation signals and communication signals, a compared measurement technique, and our method to improve constellation GDOP. Some applications of these new systems, in the fields of high-precision measurement, emergency rescue and equipment real-time monitoring, are introduced.
