摘要
本文在简述影响GPS外业观测时间的因素和BP网络误差反向传播算法后,着重讲述了如何建立预测GPS外业观测时间的BP网络模型。实际数据表明该网络在实践中具有一定的可行性,能提高工作效率。
After briefly introducing the factors of the influence on the time of GPS survey and error back propagation algorithm,the paper emphatically expounds how to establish BP network model to forecast the shortest time of GPS survey.The actual data indicates that the network is workable to a certain extent to raise efficiency in practice.
