Abstract
Interoperability of Global Navigation Satellite System (GNSS) is a hot topic in GNSS area, and a lot of excellent related researches have come into being. But, existence of differences among GNSSs cause inconvenience to users. In order to achieve interoperability and convenient for users, interoperability parameters are required. First of all, differences among GNSSs are defined based on their effects on users in position, velocity and timing (PVT). These differences may from message or/and signal, and are different in precision or/and format, which bring troubles when user is using the navigation resources from different GNSSs. To ameliorate the troubles caused by GNSS differences during PVT progress, the parameters which can represent these differences should be determined. These are ten parameters in this paper which form the GNSS interoperability parameter set, and each element of this set is defined as interoperability parameter. The interoperability parameters can be separated into signal level and message level, and should be broadcast to users in a common time reference and coordinate reference frame. Then, we discussed the definition, detection and calculation method of each interoperability parameter. At last, when broadcasting these parameters to users, there three different ways such as internet, mobile communication and commercial satellite, except the providers own links.
