    The correct way to switch off LISA-C200 and FW75-C200 modules is by means of the +CPWROFF AT command (more details in u-blox C2 series AT Commands Manual [3]). Using this method, internal software tasks are properly terminated, the current parameter settings are saved in the module’s non-volatile memory, and a proper network detach is performed.

  • Page 82: Assistnow Clients And Gnss Integration

    LISA-C modules act as a stand-alone AssistNow client, making AssistNow available with no additional requirements for resources or software integration on an external host micro controller. Full access to u-blox GNSS receivers is available via the LISA-C200, through a dedicated DDC (I C) interface, while the available GPIOs can handle the positioning unit power-on/off.

  • Page 83: Positioning Through Cellular Information: Celllocate

    CellLocate enables the estimation of device position based on the parameters of the mobile network cells visible to the specific device. To estimate its position the u-blox cellular module sends the CellLocate server the parameters of network cells visible to it using a UDP connection. In return the server provides the estimated position based on the CellLocate database.

  • Page 84: Hybrid Positioning

    3.9.2 Hybrid positioning With u-blox Hybrid positioning technology, u-blox cellular devices can be triggered to provide their current position using either a u-blox GNSS receiver or the position estimated from CellLocate . The choice depends on which positioning method provides the best and fastest solution according to the user configuration, exploiting the benefit of having multiple and complementary positioning methods.
