Dear Colleague,<br>
<br>
1. a) If you want to do differential GNSS, please do the following :<br>
run the rtkpost > enter the .o and .n file of Base and only .o file of<br>
rover as input> select dgnss in processing option> execute.<br>
b) If the data of Base is of same day as rover and of 24 hrs then you will<br>
get the dgnss solution, no issue will be arisen.<br>
c) yes you can use final ephemeris of constellations but the observation<br>
files should be of same day.<br>
<br>
2. If you want to do ppp for single receiver then you need final<br>
ehemerides, clk file, erp, antx file etc.<br>
<br>
Best regards<br>
<br>
