We are analyzing MediaTek MT3333 GNSS SoC. MT3333 multi-GNSS receiver supports GPS, Galileo, QZSS, BeiDou, GLONASS, SBAS, and Automotive applications as well. Broadcom just announces the launch of industry's first GNSS location hub for smartphone, BCM4774 is believed to support the above mentioned satellite systems. 

We are planning to extract the analog section of MT3333 to dig some interesting data and find BCM4774 if possible.  Contact us if you has interests to see some initial data. 

Dialog Semiconductor DA14580 Analog section has been imaged in lab and will be extracted soon. 

Bluetooth smart, let's see how smart this SoC will be. Some initial data is available if you are interested.
