Transient Suppression Modification for Instrument Landing System AN/GRN-27(v) (Solid State Instrument Landing System (SSILS)).

摘要

The Solid State Instrument Landing System (SSILS) AN/GRN-27(v) was experiencing excessive outages during lightning storms,which are the periods of time in which the ILS is in the most critical demand. An in-house study was made of the source and type of transients that were affecting the system. Protective methods and devices were evaluated and protective circuitry was designed. The characteristics of the transient and design criteria for a suitable modification are discussed in the report.
