METHOD FOR AUTOMATION OF SENSOR CALIBRATION OF STRAPDOWN INERTIAL SYSTEM OF UNMANNED AERIAL VEHICLE

摘要

FIELD: regulating.;SUBSTANCE: invention relates to methods for automatic calibration of strapdown inertial systems (SINS) including acceleration sensors (accelerometers) and angular rate sensors (ARS) in form of gyroscopes. The substance of the invention consists in the fact that interaction of the SINS sensors and the calibration table with the service applications located on workstations is executed by the RS-232/RS-485 protocol; in the web controller, based on the data received from the SINS sensors and stored in the database, the calibration matrices of accelerometers and gyroscopes, as well as the matrices of temperature compensation polynomials, are calculated, the calculated matrices are recorded in the database and the SINS calculator. To provide secure remote access to information resources in a secure segment of the local network, an enhanced authentication technology based on a cryptographic token generated by the web controller is used. To provide a possibility of adapting the method to an expanded number of simultaneously calibrated apparatuses (SINS), WebSockets messages are broadcast; message brokers generated by a WebSockets broadcast support module are used therefor.;EFFECT: increased productivity of the procedure of calibration of SINS sensors due to ensured automation thereof and the expanded number of simultaneously calibrated apparatuses (SINS); increased protection against unauthorised access to the information resources in the secure segment of the local network between the web controller and the service applications due to the applied enhanced authentication technology.;2 cl, 15 dwg
