GPS data for COPEX campaign carried out in 2002 in Brazil by INPE (Cachimbo Station)

This repository provides the GPS data acquired in Cachimbo station during the Conjugate Point Equatorial Experiment (COPEX) campaign in 2002. In the folders it can find the raw intensity data (FSL file) and also the summary files (SUM files), containing only with S4 index with time and satellite ID. More information about the campaign can be found in Muella et al. (2008), Abdu et al. (2009) and de Paula et al. (2010). Information about the data recording format and reading extraction procedure of this dataset can be found in Appendix B of Beach (1998). More details regarding the receiver used and extraction tools can be found at: https://gps.ece.cornell.edu/tools.php
