   22  * This API provides access to the GNSS device.
   23  *
   24  * GNSS or Global Navigation Satellite System is a satellite navigation system with global coverage.
   25  *
   26  * This API provides function to configure the GNSS device and retrieve position information.
   27  *
   28  * @section le_gnss_binding IPC interfaces binding
   29  *
   30  * All the functions of this API are provided by the @b positioningService application service.
   31  *
   32  * Here's a code sample binding to Positioning services:
   33  * @verbatim
   34    bindings:
   35    {
   36       clientExe.clientComponent.le_gnss -> positioningService.le_gnss
   37    }
   38    @endverbatim
   39  *
   40  * @section le_gnss_ControlApi GNSS Control API
   41  *
   42  * @subsection le_gnss_EnableDisable Enable/Disable GNSS device
   43  *
   44  * The application can enable/disable the GNSS device with the le_gnss_Enable()
   45  * / le_gnss_Disable() functions.
   46  * By default the GNSS device is enabled for the positioningService application service.
   47  * Also see @ref howToGNSS.
   48  *
   49  * A sample code can be seen in the following page:
   50  * - @subpage c_gnssSampleCodeEnableDisable
   51  *
   52  * @subsection le_gnss_StartStop Start/Stop GNSS device
   53  *
   54  * The application can start/stop the GNSS device with the le_gnss_Start() / le_gnss_Stop()
   55  * functions.
   56  * The default "HOT" start condition is applied and all assistance data are used.
   57  * Also see @ref howToGNSS.
   58  *
   59  * A sample code can be seen in the following page:
   60  * - @subpage c_gnssSampleCodeStartStop
   61  *
   62  * @subsubsection le_gnss_StartingMode Starting mode
   63  *
   64  * Starting modes are used only for test purposes and allow start performance measurement.
   65  * @note For more information about start performances, please refer to your specific
   66  * platform documentation.
   67  *
   68  * @subsubsection SettingConfiguration Setting configuration
   69  *
   70  * @warning The GNSS setting configuration depends on the platform. Please refer to
   71  *          @ref platformConstraintsGnss_SettingConfiguration section for full details.
   72  *
   73  * @subsubsection le_gnss_Data GNSS data
   74  * The following table describes the <b>minimum</b> required data for those starting modes:
   75  *
   76  * | GNSS Data / Starting mode  | HOT  | WARM  | COLD  | FACTORY |
   77  *| -----------------------| -----| ------| ----- | ------- |
   78  *| Broadcasted Ephemeris  | Used |  |  |  |
   79  *| Extended Ephemeris     | Used(1) | Used(2) | Used(2) | Removed (3) |
   80  *| Approximate Time and Position  | Used | Used |  |  |
   81  *| Almanac   | Used | Used | Used | Used (Factory) |
   82  *
   83  * For example, a requested HOT start without valid broadcasted ephemeris will be treated
   84  * as a WARM start.
   85  *
   86  * @note (1) Extended Ephemeris can be used if Broadcasted Ephemeris are not valid.
   87  * The Extended Ephemeris could be loaded using the le_gnss_LoadExtendedEphemerisFile()
   88  * function.
   89  * @note (2) Extended Ephemeris is used if the Extended Ephemeris file is loaded and valid.
   90  * @note (3) Extended Ephemeris are removed when a FACTORY start is requested.
   91  * The Extended Ephemeris could be loaded again using the le_gnss_LoadExtendedEphemerisFile()
   92  * function.
   93  *
   94  * @subsubsection le_gnss_TTFF Time To First Fix (TTFF)
   95  * The le_gnss_GetTtff() function provides the TTFF (first between 2-Dimensional or 3-Dimensional
   96  * position fix) of the last position fix.
   97  * The GNSS fix position is calculated by the GNSS engine. Its state can be retrieved by
   98  * le_gnss_GetPositionState() function. The GNSS fix position states are given by le_gnss_FixState_t
   99  * enum.
  100  * @note The "estimated" fix is obtained when less than 3 Satellites Vehicle (SV) are used to
  101  * establish the fix. It includes the case when no SVs are used.
  102  *
  103  * Please refer to @ref le_gnss_APIcallsRequirements. Also see @ref howToGNSS.

  106  * - @subpage c_gnssSampleCodeReStart
  107  *
  108  * @subsubsection le_gnss_InjectUtcTime Inject UTC time
  109  * The le_gnss_InjectUtcTime() function injects the UTC time into the location engine. Providing an
  110  * accurate UTC time reduces the time to find the first fix.
  111  * @note It is mandatory to enable the 'Extended Ephemeris' file injection into the GNSS device with
  112  * le_gnss_EnableExtendedEphemerisFile() before injecting time with le_gnss_InjectUtcTime API.

  244  * @subsection le_gnss_NMEA NMEA Flow
  245  * The National Marine Electronics Association (NMEA) standard defines an electrical interface
  246  * and data protocol for communications between marine instrumentation.
  247  *
  248  * The NMEA-0183, scope of this document, defines a set of frame prefixed by
  249  * $GP (concerning Global Positioning System),
  250  * $GL (concerning GLONASS)
  251  * and $GN (concerning combination of navigation systems).
  252  * For more details about NMEA standards, please refer to http://www.nmea.org/.
  253  *
  254  * That NMEA frames flow can be retrieved from the "/dev/nmea" device folder, using for example
  255  * the shell command $<EM> cat /dev/nmea | grep '$G'</EM>
  256  *
  257  * @subsection le_gnss_GetInfo Get position information
  258  * The position information is referenced to a position sample object.
  259  *
  260  * An application can register a handler to be notified of the
  261  * updated position each @ref le_gnss_AcquisitionRate, returning a position sample object.
  262  *
  263  * The GNSS information commonly used such as
  264  * device state, position, time and date, satellites information and accuracy
  265  * can be queried using the following functions:
  266  * - le_gnss_GetState()
  267  * - le_gnss_GetPositionState()
  268  * - le_gnss_GetLocation()
  269  * - le_gnss_GetAltitude()
  270  * - le_gnss_GetDate()
  271  * - le_gnss_GetTime()
  272  * - le_gnss_GetGpsTime()
  273  * - le_gnss_GetGpsLeapSeconds()
  274  * - le_gnss_GetEpochTime()
  275  * - le_gnss_GetTimeAccuracy()
  276  * - le_gnss_GetHorizontalSpeed()
  277  * - le_gnss_GetVerticalSpeed()
  278  * - le_gnss_GetDirection()
  279  * - le_gnss_GetSatellitesInfo()
  280  * - le_gnss_GetSbasConstellationCategory()
  281  * - le_gnss_GetSatellitesStatus()
  282  * - le_gnss_GetDop()
  283  * - le_gnss_GetDilutionOfPrecision()
  284  * - le_gnss_GetAltitudeOnWgs84()
  285  * - le_gnss_GetMagneticDeviation()
  286  *
  287  * le_gnss_SetDataResolution() function can be called to configure the resolution of position data
  288  * type per client session. Currently, three data types are supported:
  289  * - Vertical position accuracy provided by le_gnss_GetAltitude().
  290  * - Vertical speed accuracy provided by le_gnss_GetVerticalSpeed().
  291  * - Horizontal speed accuracy provided by le_gnss_GetHorizontalSpeed().
  292  * Each data type can be set with a resolution from 0 to 3 decimal place.
  293  *
  294  * For example, to get the vertical position accuracy with a resolution of 2 decimal places,
  295  * le_gnss_SetDataResolution() function is called with vertical position accuracy set as data type
  296  * and 2 decimal place is set as resolution, then le_gnss_GetAltitude() function is called.
  297  *
  298  * @note If le_gnss_SetDataResolution() function is not called, the position data types are received
  299  * in their default accuracies.
  300  *
  301  * le_gnss_ConvertDataCoordinateSystem() function can be called to convert a location data value
  302  * from a coordinate system to another. Currently it is possible to convert the following data
  303  * types:
  304  * - Latitude
  305  * - Longitude
  306  * - Altitude
  307  *
  308  * System coordinates source and destination are currently:
  309  * - Coordinate system WGS84
  310  * - Coordinate system PZ90
  311  *
  312  * @note Only conversion from WGS84 coordinate system to PZ90 coordinate system is currently
  313  * supported.
  314  * @note The altitude in coordinate system WGS84 is obtained by le_gnss_GetAltitudeOnWgs84()
  315  * function.
  316  *
  317  * A sample code using le_gnss_ConvertDataCoordinate() function can be seen in the following page:
  318  * - @subpage c_gnssSampleCodePosition
  319  *
  320  * le_gnss_GetDilutionOfPrecision() gets the DOP parameters (Dilution Of Precision) with a
  321  * resolution of 3 decimal places by default. This resolution can be modified by calling the
  322  * @c le_gnss_SetDopResolution() function first.
  323  *
  324  * As @c le_gnss_SetDopResolution() sets the resolution per client session,
  325  * @c le_gnss_SetDopResolution() and @c le_gnss_GetDilutionOfPrecision() functions should be called
  326  * in the same thread or client session.
  327  *
  328  * A sample code can be seen in the following page:
  329  * - @subpage c_gnssSampleCodePosition
  330  *
  331  * The handler can be managed using le_gnss_AddPositionHandler()
  332  * and le_gnss_RemovePositionHandler().
  333  * When a position is computed, the handler is called.
  334  *
  335  * The application has to release each position sample object received by the handler,
  336  * using the le_gnss_ReleaseSampleRef().
  337  *

  352  * You have to download the file before loading it.
  353  * @warning Ensure to check that the downloaded file is supported for your specific platform.
  354  *
  355  * With le_gnss_GetExtendedEphemerisValidity(), you will to get the validity of the last injected
  356  * Extended Ephemeris.
  357  *
  358  * You can enable/disable the use of the 'Extended Ephemeris' file into the GNSS device with
  359  * le_gnss_EnableExtendedEphemerisFile() / le_gnss_DisableExtendedEphemerisFile() functions.
  360  * @warning Ensure to check configuration capabilities for your specific platform.
  361  * A reboot must be required if your platform doesn't allow run-time configuration.
  362  *
  363  * A sample code can be seen in the following page:
  364  * - @subpage c_gnssSampleCodeXtra
  365  *
  366  * @subsection le_gnss_Assisted_GNSS_UP 3GPP User Plane (OMA SUPL)
  367  *
  368  * That 3GPP User Plane A-GNSS (Assisted GNSS) protocol is defined by two different standardization
  369  * bodies, 3GPP and Open Mobile Alliance (OMA). For more information, please refer to the standard.
  370  *
  371  * Both MS-Assisted and MS-Based position determination methods are supported in the User Plane.
  372  *
  373  * In MS-Assisted mode, the MS (Mobile Station) measures the signals from the GNSS satellites
  374  *, then returns the retrieved GNSS data to the SUPL (Secure User Plan Location) server, where the
  375  * position calculation is performed.
  376  *
  377  * In MS-Based mode, the MS gets the assistance data from the SUPL (Secure User Plan Location)
  378  * server. The MS measures the signals from the GNSS satellites and makes the position calculation.
  379  *
  380  * The data transport over User Plan is done using the TCP/IP protocol.
  381  *
  382  * The Assisted-GNSS mode can be configured thru the le_gnss_SetSuplAssistedMode() function.
  383  *
  384  * The supported modes are the following:
  385  * - Standalone mode: That 3GPP User Plane A-GNSS feature is deactivated.
  386  * - MS-Based mode
  387  * - MS-Assisted mode
  388  *
  389  * Moreover, the le_gnss_GetSuplAssistedMode() function reads the configured Assisted-GNSS mode.
  390  *
  391  * The SUPL server is configured using the le_gnss_SetSuplServerUrl() function. That function sets
  392  * the SUPL server URL and optionally the port number.
  393  *
  394  * The SUPL certificate to be used in A-GNSS sessions is injected through the
  395  * le_gnss_InjectSuplCertificate() function and deleted through the le_gnss_DeleteSuplCertificate()
  396  * function.
  397  * The SUPL certificate lenght given as parameter to le_gnss_InjectSuplCertificate() must be less
  398  * than LE_GNSS_SUPL_CERTIFICATE_MAX_LEN.
