Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0024] The navigation signal source used in the signal occlusion area proposed by the present invention is a "pseudo-satellite" device. It is a signal source and information source for broadcasting navigation and positioning signals and texts. It not only broadcasts navigation satellite signals, but also broadcasts accompanying signals suitable for positioning in signal occlusion areas. Some sensors are also installed to make the navigation signals The source can assist satellite navigation signals to achieve navigation enhancement, especially to solve the navigation in areas where outdoor satellite navigation signals are severely blocked. Therefore, the navigation signal source is a relatively simple "pseudo-satellite" different from the traditional sense. Because the navigation signal source is provided with civil code signals on navigation satellite...
