METHOD OF DETERMINATION OF TIME LOCK-ON OF TELEMETRY MEASUREMENTS FROM SPACECRAFT |
摘要 |
FIELD: aircraft engineering.SUBSTANCE: invention relates to determination of time lock-on of telemetry measurements from spacecraft. Proposed method comprises generation of time marks aboard the spacecraft and their transmission with measured parameters of onboard systems in generated telemetry frame to surface reception station. Note here that the Earth magnetic field intensity is measured aboard the spacecraft and its orbit parameters are measured. Obtained results the Earth magnetic field intensity is determined along with the error of time lock-on of telemetry measurements ?t from the relationshipwhere His the Earth magnetic field intensity modulus obtained from the spacecraft orbit intensity modulus, H is the Earth magnetic field intensity modulus obtained from the spacecraft onboard measurements to define time lock-on of telemetry measurements by the formula t* = t+?t, where t is time lock-on of telemetry measurements obtained by onboard time marks.EFFECT: accurate time lock-on of telemetry measurements from spacecraft. |
