If I want to get the precise coordinates of base up to 10 sm accuracy, I need to use only ppp mode?<br>

>1. If you want to get a fix coordinate of your base you can use 'OPUS' or 'AUSPOS' online services. <br>
>2. If you get position of your base using differential or rtk method use nearest igs station observation file and associate navigation file. <br>
>You may also use broadcast ehemerides or final ephemeris for more precise solution.<br>
>3. Or you may use static ppp using final ephemeris, clk and antenna files etc. <br>
