## Time Update for U & Dgreenspun.com : LUSENET : CU Statistical Orbit Determination : One Thread |

I'm having some trouble getting my time update to work for the UDU' method. I was wondering what I should be using to time update U and D. I'm assuming P doesn't need to be calculated, but I wasn't sure if it was somehow involved in the time update equations.Thanks, Rodney
