Why is there repetitive GNSS data and minor time deviation for Argos devices?

Sometimes you may find repetitive GNSS data for Argos devices and minor time deviation for each piece as shown below.

As for data repetitiveness, you can find the reason by clicking here to know how does it happens.

As for minor time deviation, it is because the collecting time (of an Argos device) is a relative time with an accuracy of 1 minute. When a piece of data is transmitted for the second time, there will be a time deviation within 1 minute. It is not an error, and you can choose either one piece of the data.
