ADIBEAM Abstract—the increase in navigation accuracy demanded by EGNOS and Galileo and their future evolution encourages the study and design of advance receiver architectures. In that direction, the ADIBEAM project focuses on the design of high accuracy ground stations, specifically GNSS Reference Stations, in order to improve its robustness in front of multipath and interference errors with the goal of achieving centimeter level tracking accuracy. The adoption of antenna arrays and digital beamforming at the ground reference station receivers is one of the most promising approaches to cope with errors induced by multipath and interference.

说明：  EtherCAT(以太网控制自动化技技)是一种用于确定性以太网的高性能技业通信协议,它扩展了IEEE 802.3 以太网标准,使得数据传输中具有可预测性定时及高精度同步等特点。这个开放性标准作为 IEC 61158 的组成部分,常用于机械设计及运动控制等应用中。EtherCAT 采用标准的IEEE802-3 以太网帧,帧结构如图 1。EtherCAT 协议直接用标准以太网的帧格嵌传输数据,并不修改其基本结构(ethercat communication)

说明：  factorialsss code in c++ and cyclic redundancy check is exceuted in c++
