Step 1: Collect GPS Data
Types of GPS Data
There are two main types of GPS data: NMEA and RINEX. NMEA data is the standard format used by most GPS receivers and contains information about position, velocity, and time. RINEX data is a more advanced format used for post-processing and analysis.
Collecting GPS Data
To collect GPS data, you will need a GPS receiver and software that can record and store the data. Many GPS receivers come with their own software, but there are also open-source options available.
