As you might guess from the name, a moving-base solution differs from the more common fixed-based solutions in that the base station is allowed to move in addition to the rover. Although it could be… Exploring moving-base solutions
I’ve had a couple questions about what’s different between my demo5 code and the 2.4.3 release code. Here’s a list of what I think are the significant differences. Any changes that I have made but… Demo5 code features
After describing my simple Pi based data logger in my last post, I stumbled across this Raspberry Pi based GPS project on diydrones.com. It uses an M8T receiver and includes a touchscreen GUI to manage… Another Raspberry Pi RTKLIB project
In the previous post, after a couple changes to the input parameters, we ended up with the following solution for the difference between two stationary, then moving Ublox receivers: During the time when the receivers… Improving RTKLIB solution: (AR lock count and elevation mask)
Recently, I have been given several raw data sets from readers to take a look at. Some of them I have been successful at improving the results and some of them I haven’t. In… Plotting Observation Data: Cycle Slips
One of my goals in this project is to make some changes to the RTKLIB solution algorithms and evaluate them specifically for my set of inputs. RTKLIB is intended to work in many different environments.… Building RTKLIB 2.4.3 code with Visual C++ 2010
Kinematic solution with RTKPOST RTKPOST is the GUI tool in RTKLIB to calculate position solutions. Most of the time I find the CUI version (RNX2RTKP) better fits my needs, but just to check everything is… Kinematic solution with RTKPOST
In the last post we used the RTKPOST GUI to generate a kinematic position solution using “ebay.obs” for the rover data and “zdv13480.15o” for the base station data. To do the equivalent run from… Kinematic solution with RNX2RTKP
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… Base station data for RTKLIB
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… Converting raw receiver data to standard text format using CONVBIN
