针对海面与航空重力测量重复测线精度评估公式在使用过程中存在的差异性问题,根据测量平差理论,推出了一组形式统一的重复测线内符合精度评估公式,并提出了使用方面的建议。
A brief analysis is made on the existing formulas of accuracy evaluation for multi- line overlapping measurements in ship-borne and airborne gravity survey..And the inconsist- ency between the formula derivations and survey adjustment theory is pointed out. Then a new set of accuracy evaluation formula is put forward and a suggestion is given for use of the new formulas.
