Example raw I/Q-file for testing GPS L1C processing in the FGI-GSRx receiver. The file is generated using [Safran's Skydel simulator](https://www.safran-group.com/products-services/skydel-gnss-simulation-software). A FGI-GSRx parameter file used to process the data and a ".mat" results-file are also provided. *Simulated signals:* GPS L1C GPS L1 C/A Galileo E1 OS BDS B1C Noise simulation: Additive white Gaussian Noise (AWGN) Environmental errors: No Orbit and clock errors: No *Visible satellites* GPS: [4, 5, 9, 11, 12, 18, 20, 25, 26, 28, 29, 31] Galileo: [2, 7, 8, 10, 11, 12, 14, 24, 25, 33] BDS: [2, 5, 8, 10, 11, 12, 13, 19, 22, 23, 25, 34, 37, 38, 43, 44, 60] *File parameters:* Date & time: 28-09-2023 23:20:00 UTC Duration: 119 seconds Center frequency: 1575.42 MHz Sampling rate: 25 MHz Quantization: 8 + 8 bit IQ Reference LLA: [60.182260 deg, 24.828537 deg, 47.248 m] *References* FGI-GSRx is available at: https://github.com/nlsfi/FGI-GSRx Pääkkönen, Into, Bhuiyan, M.
