Using GPS data for orbit determination, what should the normal value of the diagonal elements of the covariance matrix be less than that? 0.1 or 0.01 or 0.001.Thanks.

Hi,

What is the standard deviation of your observations?

Bryan

About 10 meters.Thanks.

Thanks!

I’m not an expert but I think that with a standard deviation of 10 meters you can get a covariance on the satellite position of the order of a few dozen meters.

Thanks! However, I see that the diagonal elements of the covariance matrix are all less than 1. Is there a problem with my understanding?

Is your output covariance in Cartesian elements?

Could you show us the obtained covariance?
