A suitable GNSS simulator might be quite easy to make if the bitstream could be pre-computed and just played back into a mixer with appropriate LO.</p>

<p>... i think this is technically a 0day?..</p>

<p>it is friday the 13th, post horror</p>

<p>yeah, it reads data from the sensor into a preallocated buffer that has space for about 32 satellites (i&#39;m not clear on how many exactly but definitely not more than that)</p><p>the GNSS module has 72 channels</p>

There is likely some limit (possibly implemented safely) in the GPS firmware but it may still be higher than the length of this buffer...</p>
