It is demonstrated that the solution for 141 000 order normal equations for a simulated astro - geodetic network ( 47 057 points ) and a space one ( 476 points ) iterates 4 993 times to converge to 1 10 - 18 second, taking 28 min and 47 seconds, on a pii / 233 computer, showing over 40 times more efficiency, as compared with the coefficients unadjusted
利用模擬的天文大地網( 47057點)和空間網( 476點)在pii / 233微機上解算14 . 1萬階方程組共迭代4993次(收斂至1 10 - 18角秒) ,花費機時28分47秒,與未進行系數調整相比,功效提高40多倍。
