Hi all, I am working on a GPS spoofing detection project, for which I need access to the raw GPS samples containing the PRN codes. I would need raw samples digitized at about 5Mhz so that I could acquire and track the C/A codes to use as a reference to isolate portions of the encrypted P(Y) codes. Primarily I need to correlate portions of the encrypted P(Y) code between a secure reference gps station and a vulnerable client gps device, to validate the client node. I have followed researches that have used Software Defined Radio to provide raw gps data sampled at about 5Mhz, but due to cost/scalability I would prefer to find a commercial GPS receiver that can server this purpose. I have tried U-blox NEO LEA M8T gps chip, but its raw data samples are published at 10Hz which is not nearly as fast as what I require [CODE] https://www.u-blox.com/sites/default/files/products/documents/NEO-LEA-M8T-FW3_ProductSummary_(UBX-16000801).pdf [/CODE] I would appreciate it if anyone here has a suggestion for a commercial gps chip that can provide raw gps data sampled at about 5MHz or close. Thanks
