电子式飞行仪表系统与GPS导航系统交联关系设计与实现

Designing and Realizing of Airborne EFIS and GPS Navigation System Interfacing Methods

在简要分析某型飞机上原装LTN-211奥米加导航系统与EFIS-74电子式飞机仪表系统交联特性和Trimble 2101I/O型GPS导航系统输出特性基础上,设计了该型机LTN-211换装Trimble 2101 I/O后EFIS-74与Trimble 2101 I/O新的交联关系。实际应用表明:所实现的EFIS-74与Trimble 2101 I/O交联关系全面、正确,提高了该型飞机的整机导航能力。

Based on briefly introducing about interfacing characteristics between LTN-211 OMEGA long range navigation system and EFIS-74 electronic flight instrument system installed in one carrier aircraft and output characteristics of Trimble 2101 I/O approach GPS navigation system, this paper analyzes interfacing methods between EFIS-74 and Trimble 2101I/O, which replaces LTN-211. Actual applying shows that the interfacing methods designed between EFIS-74 and Trimble 2101 I/O are complete and correct, enhancing the whole navigation abilities of the carrier aircraft.
