Embodiment Construction
[0037] The present invention will be further described below in combination with specific embodiments and accompanying drawings.
[0038] The invention discloses a method for correcting tropospheric delay without meteorological parameters, which is applicable to Chinese regions, comprising the following steps:
[0039] S1: Determine the relationship of tropospheric delay with time in China: use a parabolic model based on a quadratic function to represent the relationship of tropospheric delay with time in China, where the parabolic model is shown in formula (1):
[0040]
[0041] In formula (1), doy is the annual cumulative day, a and c are the coefficients, and ZTD is the tropospheric delay in China;
[0042] Because the tropospheric delay in China has an annual periodicity in time, and the tropospheric delay in the middle and high latitudes of China changes sharply in summer and slowly in winter, so the parabolic model can accurately reflect the temporal variation of trop...
