Embodiment Construction

[0024] First of all, it needs to be clearly pointed out that the method adopted by the embodiment of the present invention is based on the demodulation of the received satellite navigation signal, and the information such as the navigation message can be obtained. method of deception.

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] figure 1 A schematic flow chart of the first embodiment of the false detection method for satellite navigation signals of the present invention is shown. The false detection method includes the following steps:

[0027] Step S101: when the receiver is turned on, perform initial positioning through the receiver, and obtain the initial position of the receiver according to the positioning result.

[0028] Among them, the initial position of the satellite navigation and positioning receiver must be determined first. The receiver in the embodiment of the present...

Abstract

The invention discloses a false detection method of a satellite navigation signals. The false detection method of the satellite navigation signals can record the acquisition time of a current ephemeris by recording the updating time of a reference ephemeris, and calculates the time interval between the acquisition time of the current ephemeris and the updating time of the reference ephemeris so as to judge whether the time interval conforms to the updated frequency value of a broadcast ephemeris, thus achieving the false detection of the satellite navigation signals. The invention further discloses a satellite navigation positioning receiver. By means of the above-mentioned ways, anti-spoofing ability of the receiver is reinforced. In addition, the false detection method of the satellite navigation signals and the satellite navigation positioning receiver have the advantages that low cost is achieved, expansibility is strong and the like.

Description

technical field [0001] The invention relates to the field of satellite navigation, in particular to a false detection method of satellite navigation signals and a satellite navigation positioning receiver. Background technique [0002] With the widespread application of GPS and "Beidou" satellite navigation and positioning and timing services in our country, industries that have an important impact on the national economy, such as communications, electric power, transportation, etc., not only have a greater impact on the accuracy of satellite navigation, positioning and timing services The requirements are high, and the dependence on it is also greatly enhanced. Basic services and technical support are provided mainly or entirely through satellite navigation, positioning and timing services. Therefore, higher requirements are put forward for the security of satellite navigation, positioning and timing services. [0003] Disguised jamming of satellite navigation receivers by ...
