IRNSS（Indian Regional Navigation Satellite System）是印度独立开发的区域卫星导航系统，由3颗GEO（Geostationary Orbit）卫星和4颗IGSO（Inclined Geo-synchronous Orbit）构成，目前已经发射3颗卫星，整个系统预计于2015年建成。IRNSS建成之后将对南纬30°至北纬50°、东经30°至东经130°的区域提供准确的定位服务，集成IRNSS的多模卫星导航接收机将对上述区域的用户带来更好的服务。本文描述了IRNSS卫星星座、信号特点、调制方式，分析了IRNSS的SPS信号与其他卫星导航系统信号的差别，给出了在多模导航接收机芯片上集成IRNSS的方式。

IRNSS is an independent regional navigation system developed by India. The IRNSS constellation is composed of 3 Geostationary orbit (GEO) satellites and 4 Inclined Geo-synchronous orbit (IGSO) satellites. Three satellites have been launched until now. The full constellation will be operational by 2015. It is designed to provide accurate position information service to the area enclosed by the rectangle from Latitude 30 degree south to 50 degree North, Longitude 30 degree east to 130 degree east. Better user experience will be obtained in the above area through using multi-mode navigation receiver integrating IRNSS. The satellite constellation, the signal characteristics and modulation schemes of IRNSS are described and the difference of SPS signals between IRNSS and other satellite navigation system are analyzed. The method to integrate IRNSS into the multi-mode receiver is also proposed.
