Abstract

The invention discloses a handheld navigation signal simulator, belonging to the technical field of satellite navigation signals. The navigation signal simulator comprises terminal application software, a wireless data transceiver module, a baseband module, a radio frequency module, and a transmitting antenna. The terminal application software is connected with the wireless data transceiver modulethrough the wireless local area network, performs the configuration of parameters and output time, and sends the pseudo-range information and a telegraph text to the baseband module. The baseband module modulates and outputs an intermediate frequency navigation signal, and combines the multiple satellite signals. The radio frequency module performs the up-conversion on the intermediate frequencysignal of the baseband and outputs it to the transmitting antenna. According to the handheld navigation signal simulator, the handheld function of the navigation analog signal is realized by means oflocal area network wireless communication and control based on the generation of the navigation signal, and flexible use and control can be facilitated.

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...
