In order to provide communication services in a more efficient manner, and instead of using low-orbit communication satellites, we investigate an integrated navigation and communication (INAC) network by medium-orbit navigation satellites. In this article, non-orthogonal multiple access (NOMA) is investigated for facilitating the INAC information. In order to improve the received signal power level, we then introduce a reconfigurable intelligent surface (RIS)-aided INAC network. The navigation and communication signals can be reflected to the users located in the city center. Based on the different power allocation factors, navigation-oriented-INAC (NO-INAC) and communication-oriented-INAC (CO-INAC) are proposed to meet different application scenarios. The bit error ratio (BER) is calculated to illustrate the performance of both NO-INAC and CO-INAC. We analyze the results of single-point positions and multi-point positions. The numerical results demonstrate that: 1) The RIS-aided INAC network is able to successfully reflect the navigation and communication signals from the occluding satellite. 2) The proposed RIS-aided INAC network provides a new solution for satellite communications in a more efficient manner.
