+ * @param callback Handle to GnssMeasurement callback interface.
+ * @param enableFullTracking If true, GNSS chipset must switch off duty cycling. In such mode
+ * no clock discontinuities are expected and, when supported, carrier phase should be
+ * continuous in good signal conditions. All non-blacklisted, healthy constellations,
+ * satellites and frequency bands that the chipset supports must be reported in this mode.
+ * The GNSS chipset is allowed to consume more power in this mode. If false, API must behave
+ * as in HAL V1_0, optimizing power via duty cycling, constellations and frequency limits,
+ * etc.
+ *
+ * @return initRet Returns SUCCESS if successful. Returns ERROR_ALREADY_INIT if a callback has
+ * already been registered without a corresponding call to 'close'. Returns ERROR_GENERIC
+ * for any other error. The HAL must not generate any other updates upon returning this
