Hello,

I have made a simulation in Simulink representing integrated INS and GPS systems. I'd like to simulate loosing GPS signal for specific time at specific time of simulation? Which block (or set of blocks) should I use? I've thought about using a MATLAB function block and zeroing GPS signal when needed but zero signal is still a signal and I'd like it to not bring any signal at all.

Thanks in advance.

Hey, have you managed to solve this problem? I want to do a similar thing where i want my signal to be inactive after a certain time. Can you please elaborate if you have done it successfully?

thanks

Use the SImulink Clock block to get the current simulation time. https://www.mathworks.com/help/simulink/slref/clock.html and then compare this to a constant block that has the time you want to loose GPS signal.
