Embodiment 1

[0061] refer to figure 1 The flow chart of a real-time positioning method shown can be executed by electronic devices such as computers and processors. The method mainly includes steps S101 to S107:

[0062] Step S101, collecting observation values ​​of the global navigation satellite system in real time, and performing hash processing on the observation values ​​to obtain a first hash value.

[0063] Step S102, comparing the first hash values.

[0064] Step S103 , after the comparison is passed, the observed value is corrected to obtain correction information, and hash processing is performed on the correction information to obtain a second hash value.

[0065] Step S104, sending the correction information to the uplink injection station, and comparing it with the second hash value.

[0066] Step S105, after the comparison is passed, the correction information is encoded according to the RTCM differential message of the uplink injection station to obtain the encoded informa...

Abstract

The invention provides a real-time positioning method and device and electronic equipment, and relates to the technical field of real-time positioning. The method comprises the steps of collecting anobservation value of a global navigation satellite system in real time, and carrying out Hash processing on the observation value to obtain a first Hash value; comparing the first Hash value; correcting the observation value after the comparison is passed to obtain correction information, and performing Hash processing on the correction information to obtain a second Hash value; sending the correction information to an uplink injection station, and comparing the correction information with the second Hash value; encoding the correction information according to an RTCM differential message of the uplink injection station after the comparison is passed to obtain encoded information, and performing Hash processing on the encoded information to obtain a third Hash value; sending the RTCM differential message to a user station, and comparing the RTCM differential message with the third Hash value; and performing real-time positioning according to the RTCM differential message and the position data of the global navigation satellite system after the comparison is passed. According to the invention, the reliability and security of data can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of real-time positioning, in particular to a real-time positioning method, device and electronic equipment. Background technique [0002] In the prior art, satellite navigation augmentation signal transponders equipped with global distribution maps of satellite-based augmentation systems on geostationary orbit satellites can broadcast correction information to users, improve the positioning accuracy of the original satellite navigation system, and obtain positioning information . However, due to the influence of transmission distance, climatic conditions, electromagnetic interference, malicious attacks, etc., the reliability and security of each transmission of positioning information cannot be guaranteed, causing the user to receive unreliable correction data, and it will calculate an error positioning results. Contents of the invention [0003] The purpose of the present invention is to provide...
