| Abstract: | The support to real-time transport protocol （RTP） by system-in-the-loop（SITL） is studied and realized. According to the principle of SITL, data packets capturing and exchanging are investigated. RTP data packets convertion between the simulated network and the real network is analyzed. The function of SITL supporting RTP is realized. In the SITL simulation experiment of RTP protocol, the packet conversion delay and handling capability are collected. The analysis of simulation result and accuracy shows that SITL supporting RTP can test the accuracy of RTP simulation, providing references for SITL supporting user-defined protocol. |
