# GNSS codes, signals and spectrum generation for Matlab All the contents were developed for the [passive remote sensing group (RSLab)](https://prs.upc.edu/) as a part of the [Remote Sensing Laboratory](http://www.tsc.upc.edu/en/research/rslab), a research line of the [CommmSensLab Group](http://www.tsc.upc.edu/en/research/commsenslab) at the [Signal Theory and Communications Department (TSC)](http://www.tsc.upc.edu/en) of the [Universitat Politècnica de Catalunya (UPC)](http://www.upc.edu/?set_language=en). The first version of this program was uploaded in the [IEEE Remote Sensing Code Library (RSCL)](https://rscl-grss.org/) with DOI: [10.21***2/M8F59K](https://rscl-grss.org/coderecord.php?id=479) New versions of this program may be found at [GitHub](https://github.com/danipascual/GNSS-matlab). ## Contents #### \documentation + GNSS_signals_v1.0.pdf: A summary of the GNSS codes, signals, spectrum and auto-correlation functions. + Official ICD documents can be obtained from [here](https://mega.nz/#F!GXJGlKoA!Iu3S3DPCItlIXr1pQ_rI8Q). #### \prn_codes + Matlab data container (.mat) files with next unsampled codes: + GPS: L1CA, L2CM, L2CL, L5I, L5Q.
