| Abstract: | Aim To establish a kind of new Geostar/Loran-C integrated navigation system, which resolves the problem of active location in Geostar system. Methods Strengthen Geostar system using Loran-C system, the mathematics model of the location algorithm about integrated system is established, the equation is offered. Results The simulation result shows that the Geostar/Loran-C integrated system can be in position with passive way, and systematic positional accuracy can satisfy the requirement of application. Conclusion A kind of ideal integrated method has been put forward through the design of algorithm for the Geostar/Loran-C integrated system, also it has reference for the design of similar system. |
