AI Technical Summary
In long-term ground simulation tests, ground clock drift causes mis-capture of integrated navigation data, affecting the accuracy of simulation results, which is difficult to solve effectively with existing technologies.
By recording the number of simulation cycles and control cycles in the satellite navigation receiver model, and aligning the second pulse signal and simulation clock signal, the transmission cycle of the combined navigation data is adjusted in real time to ensure the synchronization of satellite navigation receiver data and inertial measurement combined data.
During the long-term simulation, the influence of ground clock drift on the test results was eliminated, ensuring the synchronization and accuracy of the integrated navigation data, and completing the hardware-in-the-loop simulation test of the control system.
