Example Dataset for PPPH-UAV Software

This dataset contains the example raw GNSS data and associated products required to test and run the PPPH-UAV software. PPPH-UAV is an open-source MATLAB-based tool designed to process raw GNSS data collected from UAVs to generate high-precision photogrammetric products.

Dataset Contents: This package includes the following files necessary for a complete PPP processing workflow:

GNSS Observation Data: Raw RINEX observation file (.obs) obtained from a UAV flight.

Precise Products: High-precision orbit (.sp3), clock (.clk), and bias (.bia) files provided by the Analysis Centers (e.g., CODE).

Antenna Calibration: Global antenna calibration file (.atx) for phase center corrections.

Auxiliary Data: Example input CSV file containing image names, GPS time tags, GPS weeks, and the three rotation angles (yaw, pitch, roll) for photogrammetric integration.

Usage:

Download and extract the contents of this dataset.

Place the files into the 6.Example directory of the PPPH-UAV repository.

Run the proc_example.m script within the MATLAB environment.
