| Abstract: | RAIM can provide integrated autonomous monitoring with redundant observation of user＇s receivers for positioning solution,and its basic functions include fault detection and fault exclusion.The paper discusses the influence of satellite＇s geometrical distribution,presents the parity vector model,introduces the principle of fault detection and exclusion using parity vector by the practical data and validates the RAIM algorithm of parity vector in the end. |
