The invention relates to globe positioning system GPS receiver technical field, in particular to a method for measuring the obscuration error of dual-frequency obscuration GPS receiver. The method uses two obscuration receivers in one antenna which are same object receivers, or one is provided with known measurement error, and another one is the object receiver, to use the two measurement errors of the two receivers to obtain the measurement error of the obscuration receiver. The method comprises that 1, the GPS signal via the antenna of the obscuration receivers receive real GPS signal, 2, setting the sample rate of the receivers, 3, analyzing the data of the two receivers, 4, calculating the high-load noise ratio measurement error and averaging, via the high-quality data, 5, calculating out the integral measurement error.
Description
technical field The invention relates to the field of GPS receivers of the global positioning system, in particular to a method for measuring errors of various observations in a dual-frequency occultation GPS receiver. Background technique GPS occultation observation is a new technology that uses the occultation GPS receiver to receive GPS satellite radio waves obliquely penetrating the atmosphere, and inverts to obtain the profile of atmospheric temperature, density, pressure and ionospheric electron density. It has high measurement accuracy, high vertical resolution, With the characteristics of global coverage, long-term stability, all-weather and no need for on-orbit calibration, its detection data are of great significance to astronomy, climatology, space weather and geodesy. The occultation GPS receiver measures the phase of the dual-frequency carrier, extracts the additional phase of the radio wave passing through the ionosphere and the atmosphere, and then inverts i...
