+ * millisecond ambiguity, the state must be set as:
+ *
+ * STATE_CODE_LOCK | STATE_BIT_SYNC | STATE_MSEC_AMBIGUOUS

+ * constellations except for Glonass where it is relative to the beginning of the Glonass system
+ * day.
+ *
+ * <p>The table below indicates the valid range of the received GNSS satellite time. These

+ * algorithms given by the getState method. If the state flag is set, then the valid measurement
+ * range is zero to the value in the table. The state flag with the widest range indicates the
