Apple Watch Series 9
Overview
The Apple Watch Series 9 was released at the same time as the Apple Watch Ultra 2. Both contain the S9 processor, but the SiP in the Apple Watch Series 9 is nothing like the Apple Watch Ultra 2. The Ultra 2 also supports multi-band GNSS using the L1 + L5 signals.
There are two different versions of the Apple Watch Series 9 SiP, corresponding to the cellular and non-cellular models. The U2 Ultra-Wideband (UWB) chip from USI is on the outside of the cellular SiP, but this is yet to be confirmed for the non-cellular model.
Teardown
Apple Watch Series 9 (non-cellular)
The outside of the non-cellular SiP is yet to be seen, so little can be said about it at this time.
The Ultra-Wideband (UWB) chip may be on the inside of the non-cellular SiP, but the GNSS chip will certainly be inside the SiP.
Apple Watch Series 9 (cellular)
The outside of the cellular SiP has a few components, including some RF components, accelerometer / gyroscope and USI UWB chip.
The GNSS chip must be on the other side of the SiP, encased within the resin and thus tricky to identify.
Summary
Little is known about the components inside the Apple Watch Series 9, especially the GNSS chip inside the SiP.
In terms of GNSS hardware the Apple Watch Series 9 could be using the Broadcom BCM47764 like the Apple Watch Series 7.
