1 Introduction

1.1 Purpose of the document

At present, has been built and is planning the construction of a satellite navigation system apart from United

States GPS system, and Russia’s GLONASS system, the European Galileo system, Beidou satellite

navigation system in China and Japan and Indian regional satellite navigation systems.

Based on module AT command manual, this document will introduce GNSS NEMA Message application

process.

Developers could understand and develop application quickly and efficiently based on this document.
