Galileo (european Sat Nav) For Qualcomm Cpus?

[zsoltsandor]

The European Space Agency and the European Global Navigation Satellite Systems Agency have been actively developing a navigation system designed for European needs. This is Galileo. Quite some satellites are already operational, the latest batch of sats launched on the 17th of November this year.

Most Xiaomi phones have A-GPS (the American sat nav "standard"), GLONASS (Russian sat nav) and BeiDou (Chinese sat nav) connections. Qualcomm has just announced this year that certain CPUs will support Galileo: https://www.qualcomm.com/news/relea...pport-galileo-across-snapdragon-processor-and

The only smartphone that officially supports Galileo is by the Spanish vendor BQ: https://www.gsa.europa.eu/newsroom/news/bq-aquaris-x5-plus-smartphone-officially-galileo-ready
This phone has a Qualcomm 652 CPU.

I am not a coder myself, but I guess that actually using the capability is "just" a "software switch", a kernel module or something similar. Maybe it is there in the BQ factory ROM somewhere.

Anyway. Why use Galileo? Because right now it has the sharpest precision.
GPS has a 5 meters precision according to Wikipedia.
GLONASS has 4.5-7.4 meters.
BeiDou has 10 meters on the public channel and 0.1 meters on the encrypted channel.

Galileo has 1 meter on the public channel and 1 cm on the encrypted channel.

I think implementing Galileo support for Qualcomm based Xiaomi phones would be the best option.

Well post this on miui forum, they code the ROM.

but I guess that actually using the capability is "just" a "software switch", a kernel module or something similar. Maybe it is there in the BQ factory ROM somewhere.

Yeah obviously.
