 Once the RTK product is configured, power it up with microSD inserted, and leave the unit in **Rover** mode. This will record all the data (NMEA, UBX, and RAWX) from the receiver to a *.ubx file. We do not yet know the location of the antenna so we stay in Rover mode to allow it to compile a large amount of satellite data. Only after we have confirmed its location should you enter **Base** mode.

 Capturing 6 hours is good, 24 is slightly better (note the logarithmic scale for position error in the graph above). Most PPP analysis services will accept more than 24 hours of data but they may truncate it to 24 hours. If you capture 30 hours of RAWX data, that’s ok, we will show you how to trim a file that is too long.

 We now need to pass the raw GNSS satellite data in RINEX format (*\*.obs*) through a post-processing center to try to get the actual location of the antenna. There are a handful of services but we’ve had great luck using the Canadian [CSRS-PPP service](https://webapp.geod.nrcan.gc.ca/geod/tools-outils/ppp.php?locale=en). The US National Geodetic Service provides a service called [OPUS](https://www.ngs.noaa.gov/OPUS/) but we found it to be frustratingly limited by file size and format issues. Your mileage may vary.

 The email will also include a [fancy PDF report](img/Corrections/SparkFun-PPP.pdf) of your antenna’s location but does not include the Cartesian coordinates we will need later.
 
 If all goes well you should have a very precise location for your antenna. For SparkFun RTK products we are most interested in ECEF coordinates. [ECEF](https://en.wikipedia.org/wiki/ECEF) is *fascinating*. Rather than lat and long, ECEF is the number of meters from the internationally agreed-upon reference frame of the center of mass of the Earth. Basically, your ECEF coordinates are the distance you are from the *center of the Earth*. Neat.
