Abstract

The invention relates to a hand-held navigation signal simulator, which belongs to the technical field of satellite navigation signals. Including: terminal application software, wireless data transceiver module, baseband module, radio frequency module and handheld navigation signal simulator for transmitting antenna. The terminal application software connects to the wireless data transceiver module through the wireless local area network. The terminal application software configures the parameters and output time, and sends the pseudo-range information and message content to the baseband module; the baseband module modulates and outputs the intermediate frequency navigation signal, and transmits the multiple satellite signals Combining; the radio frequency module up-converts the baseband intermediate frequency signal and outputs it to the transmitting antenna. Based on the generation of the navigation signal, the present invention realizes the hand-held function of the navigation analog signal by using the wireless communication and control mode of the local area network, and can be used and controlled conveniently and flexibly.

Description

technical field [0001] The invention belongs to the technical field of satellite navigation signals, in particular to a hand-held navigation signal simulator. Background technique [0002] At present, with the continuous use of navigation and positioning in life, Beidou and GPS are representatives of satellite navigation systems, and their navigation terminals are more and more widely used. For the rapid expansion of various needs, the forms of navigation terminals are also in diversification. In the rapid development, it is not limited to the use of military equipment, smart phones, smart watches, car navigators, etc. [0003] From design to production of each navigation terminal device, a navigation signal simulator is required to provide a simulated navigation signal environment to complete the debugging and testing of the navigation terminal device. However, the current navigation signal simulators are inconvenient to carry, or have relatively high requirements on the u...
