TAT100 System settings
GNSS Source settings
User can configure which GNSS system(s) to use.
User has a choice to use only one system between GPS, GLONASS, Galileo or Beidou and it is possible to choose two or three systems together. One exception is that you cannot combine BeiDou and GLONASS systems together.
Examples of non-configurable GNSS source combinations are:
- GLONASS + BeiDou;
- Galileo + GLONASS + BeiDou;
- GPS + GLONASS + BeiDou;
- GPS + Galileo + GLONASS + BeiDou.
List of configurable GNSS sources:
- GPS only;
- GPS + BeiDou;
- GPS + GLONASS;
- GPS + GLONASS + Galileo.
User can choose which protocol version to use for data sending to server.
Tracking with LBS
LBS - location based services. It helps us to find the approximate location without using a GNSS, but using cell towers information instead. Device cannot find the location using LBS by itself, approximate location is calculated on the server side according to the information provided by the device. Therefore, to locate a unit by LBS the device should send at least 4 parameters: mcc, mnc, lac, cell ID.
- If LBS is selected as a location source, the device will send information about the cell towers to the server and will not use GNSS.
- If GNSS or LBS is selected, device will use GNSS is the satellites are visible, if not - it will start sending cell towers information to the server, which will be able to calculate the approximate location using LBS.
Also, GSM Cell ID and Active GSM Operator should have at least Low priority in I/O settings.
User can select which NTP server (it is possible to configure up to two servers) and what time period to use to re-synchronize time.
