结合TIK正则化算法和移去-恢复技术对航空重力测量数据进行向下延拓的仿真实验。TIK正则化算法能有效的抑制高频噪声和解决向下延拓不稳定的问题。在向下延拓过程中,测量高度、地形引力等因素对延拓结果有影响。利用移去-恢复技术能有效缓解测量高度及地形对航空重力数据向下延拓的影响。仿真实验将不同高度的重力异常向下延拓,研究高度和地形对向下延拓的影响,实验结果表明,在条件允许的情况下,测量高度应该尽可能的低,而且在进行向下延拓前需利用移去-恢复技术对其进行地形改正。

The dominant source of error in VLBI phase-referencing is the troposphere at observing frequencies above 5 GHz. We compare the tropospheric zenith delays derived from VLBI and GPS data at VLBA station
The algorithm of using one-day-arc to integrate n-days-arc by orbit overlaying is discussed in detail. An example is given, which proves that the orbit integration method can improve the precision of
SVLBI (space very long baseline interferometry) has some important potential applications in geodesy and geodynam- ics, for which one of the most difficult tasks is to precisely determine the orbit of
