Dear Nguyen,

I've never actually had that problem for OS118. I'm looking forward to see your code. I'll also look into the G matrix to see what the issue is.

Best regards,

Cliff

Hi Cliff,

I have solved the problem of "floating point error:stack fault" for OS118 when compiling with BC5.02.

We just need to catch the error signal before running navfix(), (using <signal.h> library), and jump to next routine if error happens. I wrote code already, it overcomes so well, but I need to test more

And also I found a critical problem, i.e. matrix G in pos_vel_tim_a() has size of [4x4], I think it should be [4xnsl]

I will send you the code when all finished testing

Best regard

Long Nguyen
