Embodiment 1

[0027] refer to figure 1 As shown, Embodiment 1 of the present invention provides a GPS module positioning validity verification method, comprising the following steps:

[0028] S101. Obtain GPS satellite positioning information, where the GPS satellite positioning information includes at least 4 effectively positioned GPS satellites and numbers of each effectively positioned GPS satellite;

[0029] Specifically, the GPS satellite positioning information includes the number of GPS satellites, the number of GPS satellites and the carrier-to-noise ratio of GPS satellites;

[0030] Generally, when performing more accurate 3D positioning, it is necessary to obtain at least 4 GPS satellite positioning information, and no more than 12 satellites at most.

[0031] S102. Obtain the carrier-to-noise ratio of the effectively positioned GPS satellite;

[0032] Specifically, while obtaining the effectively positioned GPS satellites, the carrier-to-noise ratio of these effectively positi...

Embodiment 2

[0044] refer to figure 2 As shown, Embodiment 2 of the present invention provides a GPS module positioning validity verification method, comprising the following steps:

[0045] S201. Obtain GLONASS satellite positioning information, where the GLONASS satellite positioning information includes at least four effectively positioned GLONASS satellites and numbers of each effectively positioned GLONASS satellite;

[0046] In addition to the GPS satellite positioning system, the general car system also supports the GLONASS satellite positioning system, so it can also be positioned by obtaining GLONASS satellite positioning information.

[0047] S202. Obtain the carrier-to-noise ratio of the effectively positioned GLONASS satellite;

[0048] The GPGSV positioning information obtained by GPS positioning is modified and adjusted appropriately according to the needs, and the AT command processing function is written on the application side to process the obtained GPS positioning info...

Embodiment 3

[0057] refer to image 3 , Embodiment 3 of the present invention provides a GPS module positioning validity verification device, including a satellite acquisition unit 10 , a carrier-to-noise ratio unit 20 , and a judging unit 30 .

[0058] The satellite acquisition unit 10 is used to acquire satellite positioning information, and the satellite positioning information includes at least 4 effective positioning satellites and the numbers of each effective positioning satellite;

[0059] Specifically, most positioning devices generally support both GPS positioning and GLONASS positioning systems, so the acquired satellite positioning information may be information of GPS positioning satellites or information of GLONASS positioning satellites. Generally, in order to ensure the accuracy of positioning, at least four effective positioning satellite information should be obtained.

[0060] A carrier-to-noise ratio unit 20, configured to obtain the carrier-to-noise ratio of the effec...

Abstract

The invention discloses a method and device for verifying the effectiveness of GPS module positioning, comprising: acquiring satellite positioning information, the satellite positioning information including at least four effective positioning satellites and the numbers of each effective positioning satellite; acquiring the effective positioning satellites Carrier-to-noise ratio; determine whether the carrier-to-noise ratio is between 30 and 65; if the carrier-to-noise ratio is between 30 and 65, then determine that the GPS module positioning is valid. The invention realizes simpler and more accurate verification of the positioning validity of the GPS module.

Description

technical field [0001] The invention relates to a GPS module positioning validity verification method and device. Background technique [0002] Due to the rapid development of the existing Internet of Things field, the rapid development of the Internet of Vehicles is one of the most promising fields in this field. At present, the vehicle-mounted modules basically have GPS positioning functions, so that effective information such as driving trajectory, speed, and orientation can be grasped in real time. [0003] The more commonly used positioning technologies now include GPS positioning technology, GLONASS positioning technology, Beidou positioning technology, and Galileo positioning technology. GPS positioning technology is the most commonly used. It consists of 24 satellites, which are distributed on 6 orbital planes whose intersections are 60 degrees apart. The positioning accuracy is about 10 meters, and it is used for both military and civilian purposes. [0004] The I...
