Terrain Integrity Monitoring Studies using Kalman Filter for SVS

Srikanth K P, Kamali C, Abhay Pashilkar

An important component of Synthetic Vision System is the terrain database. As the pilot relies on the terrain database, the integrity of database has to be monitored continuously. The integrity monitor checks for consistency between sensed terrain profile from DGPS and radar altimeter data and the terrain profile provided by static elevation data. This paper discusses integrity check of the information derived from terrain databases using DGPS and radar altimeter. Kalman filtering is used to bias errors in vertical domain.
