GPS广域增强系统的电离层延迟网格校正法

Grid Algorithms of Ionospheric Delay in a GPS Wide Area Augmentation System

本文介绍了卫星信号电离层延迟的网格校正法原理和算法。最后，使用１９９６年１１月在天津、西安和长春三地的实测数据对网格法性能进行了评估。

The principle and algorithm of ionospheric delay correction using a grid mapping scheme is introduced. The performence of the grid algorithms is evaluated using the data measured in Tianjin, Xi'an and Changchun of China in November 1996.
