The standard for the selection of the appropriate GPS in the outdoor environment & the analysis of the performance for the improvement of reception

For the recognition of the outdoor location, the level of accuracy is determined based on the performance of the GPS. In order to increase the level of accuracy for the GPS, it is required to select the GPS which is appropriate for the outdoor environment. For such a purpose, it is necessary to know the factors related to the standard for the selection of the GPS and the improvement of the performance. In this paper, we compare the hardware performances of the GPS and experimented the application methods of the GPS based on the environment. Through such a process, we suggest the standard for the selection of the GPS in the outdoor environment.
