RELIABLE AND RELIABLE METHOD, DEVICE AND SYSTEM FOR REAL-TIME SPEED MEASUREMENT AND CONTINUOUS POSITION DETECTION Russian patent published in 2020 - IPC G01C21/00 B61L25/02 

FIELD: measurement.

SUBSTANCE: invention discloses a method, a device and a system for measuring speed in real time and continuous position determination, comprising: detecting data of inertial navigation provided by a source of inertial navigation signal located on a train; detecting correction data output by the modified signal source, wherein the modified signal source comprises a satellite signal source located on the train, and correction data comprises satellite data; if correction data are lost, determination of current speed and position of train using inertial navigation data; otherwise, use of correction data to correct inertial navigation data and determine current train speed and position according to corrected inertial navigation data. Inertial navigation data and corrected data are taken into account simultaneously. When correction data are not lost, real-time speed measurement and continuous position determination can be successfully performed by correction data and inertial navigation data; even if correction data are lost, real-time speed measurement and continuous positioning can be carried out using inertial navigation data, and high stability, reliability and accuracy are provided.

EFFECT: stable and reliable method, device and system for real-time speed measurement and continuous position determination are disclosed.
