This page lists the GNSS chipsets that are used in the Garmin Instinct watches.
It should be noted that the Instinct is not supported by Windsurfing application or GPSTC V4.
The various models are listed in reverse-chronological order. The release dates are generally from Garmin announcements.
The Instinct 3 + Instinct E were released after the fēnix 8, so may use an Airoha or Synaptics GNSS chipset.
Analysis of data from the Instinct 3 AMOLED suggests it is using an Airoha chipset.
