Why is the last GNSS fix of a track for a day different from that for a month or a year?

When you generate the track for a day, data center displays all of the GNSS fixes of the track. However, when you generate the track for a month or a year, data center only displays the last successful GNSS fix of each day in the month or the year.

Some devices may not transmit data strictly according to setting sometimes (mostly because of poor network coverage). For Year and Month mode, as a result, the system is designed to check and include newly transmitted GNSS fixes at UTC 00:00 only on odd days (such as 1st July, 3rd July and 5th July, etc.). So, for Year and Month mode, only after that can you see the latest track.

For example, we are viewing track a device on 2021-09-23. The GNSS fix in red box is the last successfully transmitted GNSS fix. Under Day mode, the End is the GNSS fix in red box. However, under Year or Month mode, the End is the GNSS fix in green box, which was checked and included into the latest tracking route by system at exactly 2021-09-23 00:00:00. The GNSS fixes transmitted after it will be checked and included by system at 2021-09-25 00:00:00.

Note: If you need to see all GNSS fixes of a device in a map, you can export the data to KML format and open it with Google Earth.
