Base station data for RTKLIB
RTKLIB has a number of different algorithms it can use to calculate position. The first two in the list are “Single” and “DGPS”. Both of these methods use only the pseudorange data and not the…
Converting raw receiver data to standard text format using CONVBIN
At this point, we have collected raw receiver output data in a Ublox binary format file. We need to convert this to RINEX format before RTKLIB will process it. RINEX (Receiver Independent Exchange Format) is…
Improving RTKLIB solution: (Receiver Dynamics and Error Ratio)
In the previous posts, I demonstrated reasonably clean looking solutions using the default RTKLIB configuration options for rover data from a roving M8N receiver and base data from a stationary COREX base station. I also…
Adding a radio link
In the last post I described setting up RTKNAVI in a simple configuration with both receivers connected directly to a laptop. While this is a good way to become familiar with RTKNAVI, it is not…
RTKLIB: Customizing the input configuration file
Note: There is a more up to date version of this tutorial on my blog. One of the nice things about RTKLIB is that it is extremely configurable and has a whole slew of…
Getting started with RTKNAVI
This tutorial assumes you have both base and rover receiver connected directly to your laptop, and that you have an appropriate command (xxx.cmd) and config files for your receiver (xxx.conf). If you are not…
Getting started with RTKLIB
At this point, we have verified that the GPS hardware and the link to the PC are working properly, and are ready to start using RTKLIB to collect and process the raw GPS data. Start…
Configuring and testing the GPS receiver
At this point, the GPS receivers are connected to your PC through the USB port and are ready to configure and verify that all is working OK.Ublox provides a nice evaluation software package for Windows…
Connecting the GPS receiver to a PC
For practical use, most likely you will want to eventually connect the GPS receivers to battery powered low cost single board computers, such as a Raspberry Pi or Beaglebone, to make them portable and stand-alone.…
Selecting a GPS receiver
[Update 6/7/17: The newest version of the M8N is no longer usable with RTKLIB. See this post for details] The first thing you will need to begin your journey into low-cost precision GPS is a receiver…
