PURPOSE AND SCOPE

This EUROCAE Minimum Operational Performance Specification (MOPS) specifies the minimum performance requirements of the Multilateration (MLAT) System which is one of the co-operative sensors for use in Advanced Surface Movement Guidance and Control Systems (A-SMGCS). Chapter 1 of this document provides the necessary information to understand the need for technical characteristics and tests of this MLAT system that are described in the following chapters. This chapter describes the typical applications of the system and the operational objectives and along with EUROCAE ED87A, Minimum Aviation System Performance Specifications for A-SMGCS, forms the basis for performance criteria stated in chapters 2 and 3. Definitions and abbreviations essential to the proper understanding of this document are also provided in Chapter 1.

Chapter 2 describes the different physical and technical components of the MLAT system and contains general design requirements for use as part of an A-SMGCS.

Chapter 3 contains the Minimum Operational Performance Requirements for the MLAT system, defining performance under all environmental conditions likely to be encountered.

Chapter 4 identifies laboratory means of testing performance characteristics of the MLAT equipment under conditions representative of those that may be encountered in actual operations.

Chapter 5 describes recommended test procedures for demonstrating compliance with Chapters 2 and 3 in the factory or laboratory.

Chapter 6 describes recommended test procedures for demonstrating compliance with the requirements of Chapter 2 and 3 for the installed MLAT system.
