Dear IGS Colleagues:</div><div style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: 13px; background-color: rgba(255, 255, 255, 0.917969); ">I am a master student in electrics and electronics engineering in Turkey. I have used gps for my master thesis study and now i am writing a theoritical background about gps technology. I downloaded some documents using internet but for the gps errors and biases i need the actual values in addition to the values exist in those documents which belong to past years. I looked through the link <a href="http://igscb.jpl.nasa.gov/components/prods.html" target="_blank" style="color: rgb(17, 85, 204); ">http://igscb.jpl.nasa.gov/components/prods.html</a> and as i see the values there belong to the year 2009. And also, for example; under the Atmospheric parameters title in that link there is a parameter called final trpospheric zenith path delay, is this the one i am looking for as the so-called term tropospheric error? How can i get the most actual values for epehemeris, tropospheric, ionospheric and satellite clock errors? </div>
