- The Chinese VLBI Network correlator has been successfully adopted in the China's lunar exploration project for probe tracking. However, due to the probe orbit maneuver, sometimes the error of the predicted VLBI time delay can be quite large. The correlator fringe search module needs new methods to tackle the multi-processors environment parallel problem and to keep the real-time ability. This paper presents a high-speed parallel fringe search algorithm for the VLBI software correlator working on the cutting-edge computer cluster. Guided by the fringe search module, CVN software correlator accomplished the real-time data correlation and supported the first Chinese lunar surface soft landing in CE-3 mission.
