On satellite Rnss and RDSS

Noun Explanation: Rnss and RDSS

There are two types of satellite radio services that serve the user's location. One is the satellite radio navigation business, the English full name Radio Navigation satellite System, the abbreviation RNSS, receives the satellite radio navigation signal by the user, autonomously completes at least to 4 satellites the distance measurement, carries on the user position, the speed and the navigation parameter computation. GPS and other systems are typical RNSS systems.

The other is the satellite radio measurement business, the English full name Radio Determination Satellite Service, abbreviated RDSS. User-to-satellite distance measurement and location calculation can not be completed independently by the user itself, must be completed by the external system through the user's response. It is characterized by user response, in the completion of positioning, the completion of the external system of the user Location report, but also to achieve the integration of positioning and communication, to achieve NAVCOMM integration in the same system.

The so-called RNSS and RDSS integration concept, is in the satellite navigation system navigation satellite and Operation control application system simultaneously integrates RNSS and RDSS two kinds of business. The system can provide users with continuous positioning, speed capacity (so-called passive navigation positioning), but also for non-information transmission of High security level location report. The integration of navigation and communication can be embedded in each other and enhance each other.
