No PVT with TEXBAT Dataset

[aphalmor]

I'm using PocketSDR to process the TEXBAT dataset however I'm having some issues. In some cases, the signal-to-noise ratio is very low across all satellites even when using high transmitter gain and no position is locked. Other times, with good S/N, the GPST is received but it's wrong, and there's no position lock. The wrong GPST might be expected in spoofed parts of the dataset, but it also happens in clean parts, which seems like a problem.

Any idea on how to improve?
