摘　　要：给出了在GPS多基线解算模式下,直接形成单差观测方程和双差观测方程权阵的公式,避免了对协因数矩阵的求逆,提高了形成法方程的速度。通过算例分析比较了直接形成权阵和通过对协因数矩阵求逆得到权阵的运算速度,结果表明:直接形成权阵的方法在计算速度上具有明显的优势。In this paper, the formulas directly forming weight matrix of single-differenced observation equations and doub- le-differenced observation equations are developed. The methods forming weight matrix have been realized in matlab lan- guage, and compared with the teaditional methods for multiple baseline solution in the speed, the result indicates that the new methods forming the weight matrix of differenced observation equations for multiple baseline solution are more effi- cient.
