How does Rinex process data?
RINEX files can be processed with RD files following this procedure:
- Save a copy of the RD file to a new folder and save a copy of the RINEX “observation” file(s) to a different folder.
- If available, save the “navigation” (.
- Open the RD file with NAVsolve and go to the “Process” page.
- In the “Base station” tab:
What is differential correction?
Differential correction techniques are used to enhance the quality of location data gathered using global positioning system (GPS) receivers. The base station receiver calculates its position based on satellite signals and compares this location to the known location.
Which are commercial software for post processing in GPS?
Commercial GPS/GNSS Post-processing Software
| Software | Developer/Company |

What is Rinex what are the files you get in Rinex format?
In the field of geodesy, Receiver Independent Exchange Format (RINEX) is a data interchange format for raw satellite navigation system data. The RINEX format is designed to evolve over time, adapting to new types of measurements and new satellite navigation systems. The first RINEX version was developed by W.
What do you need to know about differential GPS correction?
One thing is for sure, no matter what, you have to have some source of corrections to collect GPS data for GIS mapping. It’s commonly referred to as differential GPS correction. Essentially, your GPS receiver needs to reference another GPS receiver (base station) that’s set up on a known position.
What do you need to post process GPS data?
When you’re collecting GPS data that’s going to be post-processed, you need a GPS receiver (and software) that’s going to be able to record satellite observation data. Otherwise, data is collected as one normally would in the field, whether it’s utility poles, manhole covers, road centerlines or polygons of any sort.
Which is better post processing or real time DGPS?
There are several advantages and disadvantages to both post-processing and real-time DGPS for GPS mapping. The primary advantage of post-processing is that you don’t have to worry about a wireless data connection in the field. The primary advantage of real-time DGPS is that you get much better accuracy in the field.
Are there any sources of GPS / GNSS corrections?
There are three sources of GPS/GNSS corrections available to users who desire reliable GPS/GNSS accuracy in the sub-meter to three meter range: SBAS, DGPS and post-processing. Dr. Michael Whitehead, Chief Scientist at Hemisphere GPS, will join me in presenting a background on the three technologies as well as the strengths and weaknesses of each.
