   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 shall start the GNSS device calling le_gnss_Start() function.
   55  * The other starting functions that allow to start or restart the GNSS devices in particular modes
   56  * (see @ref le_gnss_StartingMode) are only used for test purposes and allow start performance
   57  * measurement.
   58  * The application shall stop the GNSS device calling le_gnss_Stop() function.
   59  *
   60  * A diagram of GNSS device state machine showing how to use the different starting fonctions can be
   61  * seen at @ref howToGNSS.
   62  *
   63  * A sample code can be seen in the following page:
   64  * - @subpage c_gnssSampleCodeStartStop
   65  *
   66  * @subsubsection le_gnss_StartingMode Starting mode
   67  *
   68  * Starting modes are used only for test purposes and allow start performance measurement.
   69  * @note For more information about start performances, please refer to your specific
   70  * platform documentation.
   71  *
   72  * @subsubsection le_gnss_startMode Start the GNSS device in the specified starting mode
   73  * The le_gnss_StartMode() function clears the @ref le_gnss_Data according to the starting mode and
   74  * starts the GNSS device.
   75  * In HOT mode, no data are cleared, the GNSS is started with its available data. It is equivalent
   76  * to @ref le_gnss_Start() function. In WARM mode, GNSS is started after the Ephemeris are cleared.
   77  * In COLD mode, GNSS is started after all data are cleared except Almanac and in Factory mode GNSS
   78  * is started after default data are set.
   79  *
   80  * @subsubsection le_gnss_ForceHotRestart Restart the GNSS device in HOT mode
   81  * The le_gnss_ForceHotRestart() function performs a "HOT" restart of the GNSS device. The current
   82  * GNSS session is stopped, then started using the available @ref le_gnss_Data.
   83  * Please refer to @ref le_gnss_APIcallsRequirements. Also see @ref howToGNSS.
   84  *
   85  * @subsubsection le_gnss_ForceWarmRestart Restart the GNSS device in WARM mode
   86  * The le_gnss_ForceWarmRestart() function performs a "WARM" restart of the GNSS device. The current
   87  * GNSS session is stopped, then started using the available @ref le_gnss_Data.
   88  * Please refer to @ref le_gnss_APIcallsRequirements. Also see @ref howToGNSS.
   89  * @Note This API has a platform dependent feature. Please refer to
   90  * @ref platformConstraintsGnss_WarmRestart for further details.
   91  *
   92  * @subsubsection le_gnss_ForceColdRestart Restart the GNSS device in COLD mode
   93  * The le_gnss_ForceColdRestart() function performs a "COLD" restart of the GNSS device. The current
   94  * GNSS session is stopped, then started using the available @ref le_gnss_Data.
   95  * Please refer to @ref le_gnss_APIcallsRequirements. Also see @ref howToGNSS.
   96  *
   97  * @subsubsection le_gnss_ForceFactoryRestart Restart the GNSS device in FACTORY mode
   98  * The le_gnss_ForceFactoryRestart() function performs a "FACTORY" restart of the GNSS device.
   99  * The current GNSS session is stopped, then started using the available @ref le_gnss_Data.
  100  * Please refer to @ref le_gnss_APIcallsRequirements. Also see @ref howToGNSS.
  101  *
  102  * @subsubsection le_gnss_Data GNSS data
  103  * The following table describes the <b>minimum</b> required data for those starting modes:
  104  *
  105  * | GNSS Data / Starting mode  | HOT  | WARM  | COLD  | FACTORY |
  106  *| -----------------------| -----| ------| ----- | ------- |
  107  *| Broadcasted Ephemeris  | Used |  |  |  |
  108  *| Extended Ephemeris     | Used(1) | Used(2) | Used(2) | Removed (3) |
  109  *| Approximate Time and Position  | Used | Used |  |  |
  110  *| Almanac   | Used | Used | Used | Used (Factory) |
  111  *
  112  * For example, a requested HOT start without valid broadcasted ephemeris will be treated
  113  * as a WARM start.
  114  *
  115  * @note (1) Extended Ephemeris can be used if Broadcasted Ephemeris are not valid.
  116  * The Extended Ephemeris could be loaded using the le_gnss_LoadExtendedEphemerisFile()
  117  * function.
  118  * @note (2) Extended Ephemeris is used if the Extended Ephemeris file is loaded and valid.
  119  * @note (3) Extended Ephemeris are removed when a FACTORY start is requested.
  120  * The Extended Ephemeris could be loaded again using the le_gnss_LoadExtendedEphemerisFile()
  121  * function.
  122  *
  123  * @subsubsection SettingConfiguration Setting configuration
  124  *
  125  * @warning The GNSS setting configuration depends on the platform. Please refer to
  126  *          @ref platformConstraintsGnss_SettingConfiguration section for full details.
  127  *
  128  * @subsubsection le_gnss_TTFF Time To First Fix (TTFF)
  129  * The le_gnss_GetTtff() function provides the TTFF (first between 2-Dimensional or 3-Dimensional
  130  * position fix) of the last position fix.
  131  * The GNSS fix position is calculated by the GNSS engine. Its state can be retrieved by
  132  * le_gnss_GetPositionState() function. The GNSS fix position states are given by le_gnss_FixState_t
  133  * enum.
  134  * @note The "estimated" fix is obtained when less than 3 Satellites Vehicle (SV) are used to
  135  * establish the fix. It includes the case when no SVs are used.
  136  *
  137  * Please refer to @ref le_gnss_APIcallsRequirements. Also see @ref howToGNSS.
  138  *
  139  * A sample code can be seen in the following page:
  140  * - @subpage c_gnssSampleCodeReStart
  141  *
  142  * @subsubsection le_gnss_InjectUtcTime Inject UTC time
  143  * The le_gnss_InjectUtcTime() function injects the UTC time into the location engine. Providing an
  144  * accurate UTC time reduces the time to find the first fix.
  145  * @note It is mandatory to enable the 'Extended Ephemeris' file injection into the GNSS device with
  146  * le_gnss_EnableExtendedEphemerisFile() before injecting time with le_gnss_InjectUtcTime API.
  147  * @warning Your GNSS device may require a restart to take into account the enabling of the
  148  * 'Extended Ephemeris' file injection.
  149  * Please refer to your platform documentation @ref platformConstraintsGnss_SettingConfiguration for
  150  * further details.
  151  *
  152  * @subsection le_gnss_AcquisitionRate Acquisition rate
  153  * The GNSS position is computed and delivered each acquisition rate. The acquisition rate defines
  154  * the time interval that must elapse between two final GPS positions calculation and reports.
  155  * Its default value is 1 second.
  156  * The application can configure/retreive the GNSS device acquisition rate with the
  157  * le_gnss_SetAcquisitionRate() / le_gnss_GetAcquisitionRate() functions.
  158  *
  159  * Please refer to @ref le_gnss_APIcallsRequirements.
  160  *
  161  * @subsection le_gnss_EnableDisableExternalLna Control EXT_GPS_LNA_EN signal
  162  * The le_gnss_EnableExternalLna() function enables the EXT_GPS_LNA_EN signal. The pin is set high
  163  * when the GNSS state is active, and set low when the GNSS state is inactive.
  164  *
  165  * The le_gnss_DisableExternalLna() function disables the EXT_GPS_LNA_EN signal. The pin remains off
  166  * regardless of the GNSS state.
  167  *
  168  * Please refer to @ref le_gnss_APIcallsRequirements.
  169  *
  170  * A sample code can be seen in the following page:

  282  * @subsection le_gnss_NMEA NMEA Flow
  283  * The National Marine Electronics Association (NMEA) standard defines an electrical interface
  284  * and data protocol for communications between marine instrumentation.
  285  *
  286  * The NMEA-0183, scope of this document, defines a set of frame prefixed by
  287  * $GP (concerning Global Positioning System),
  288  * $GL (concerning GLONASS)
  289  * and $GN (concerning combination of navigation systems).
  290  * For more details about NMEA standards, please refer to http://www.nmea.org/.
  291  *
  292  * That NMEA frames flow can be retrieved from the "/dev/nmea" device folder, using for example
  293  * the shell command $<EM> cat /dev/nmea | grep '$G'</EM>
  294  *
  295  * @subsection le_gnss_GetInfo Get position information
  296  * The position information is referenced to a position sample object.
  297  *
  298  * An application can register a handler to be notified of the
  299  * updated position each @ref le_gnss_AcquisitionRate, returning a position sample object.
  300  *
  301  * The GNSS information commonly used such as
  302  * device state, position, time and date, satellites information and accuracy
  303  * can be queried using the following functions:
  304  * - le_gnss_GetState()
  305  * - le_gnss_GetPositionState()
  306  * - le_gnss_GetLocation()
  307  * - le_gnss_GetAltitude()
  308  * - le_gnss_GetDate()
  309  * - le_gnss_GetTime()
  310  * - le_gnss_GetGpsTime()
  311  * - le_gnss_GetGpsLeapSeconds()
  312  * - le_gnss_GetEpochTime()
  313  * - le_gnss_GetTimeAccuracy()
  314  * - le_gnss_GetHorizontalSpeed()
  315  * - le_gnss_GetVerticalSpeed()
  316  * - le_gnss_GetDirection()
  317  * - le_gnss_GetSatellitesInfo()
  318  * - le_gnss_GetSbasConstellationCategory()
  319  * - le_gnss_GetSatellitesStatus()
  320  * - le_gnss_GetDop()
  321  * - le_gnss_GetDilutionOfPrecision()
  322  * - le_gnss_GetAltitudeOnWgs84()
  323  * - le_gnss_GetMagneticDeviation()
  324  *
  325  * le_gnss_SetDataResolution() function can be called to configure the resolution of position data
  326  * type per client session. Currently, three data types are supported:
  327  * - Vertical position accuracy provided by le_gnss_GetAltitude().
  328  * - Vertical speed accuracy provided by le_gnss_GetVerticalSpeed().
  329  * - Horizontal speed accuracy provided by le_gnss_GetHorizontalSpeed().
  330  * Each data type can be set with a resolution from 0 to 3 decimal place.
  331  *
  332  * For example, to get the vertical position accuracy with a resolution of 2 decimal places,
  333  * le_gnss_SetDataResolution() function is called with vertical position accuracy set as data type
  334  * and 2 decimal place is set as resolution, then le_gnss_GetAltitude() function is called.
  335  *
  336  * @note If le_gnss_SetDataResolution() function is not called, the position data types are received
  337  * in their default accuracies.
  338  *
  339  * le_gnss_ConvertDataCoordinateSystem() function can be called to convert a location data value
  340  * from a coordinate system to another. Currently it is possible to convert the following data
  341  * types:
  342  * - Latitude
  343  * - Longitude
  344  * - Altitude
  345  *
  346  * System coordinates source and destination are currently:
  347  * - Coordinate system WGS84
  348  * - Coordinate system PZ90
  349  *
  350  * @note Only conversion from WGS84 coordinate system to PZ90 coordinate system is currently
  351  * supported.
  352  * @note The altitude in coordinate system WGS84 is obtained by le_gnss_GetAltitudeOnWgs84()
  353  * function.
  354  *
  355  * A sample code using le_gnss_ConvertDataCoordinate() function can be seen in the following page:
  356  * - @subpage c_gnssSampleCodePosition
  357  *
  358  * le_gnss_GetDilutionOfPrecision() gets the DOP parameters (Dilution Of Precision) with a
  359  * resolution of 3 decimal places by default. This resolution can be modified by calling the
  360  * @c le_gnss_SetDopResolution() function first.
  361  *
  362  * As @c le_gnss_SetDopResolution() sets the resolution per client session,
  363  * @c le_gnss_SetDopResolution() and @c le_gnss_GetDilutionOfPrecision() functions should be called
  364  * in the same thread or client session.
  365  *
  366  * A sample code can be seen in the following page:
  367  * - @subpage c_gnssSampleCodePosition
  368  *
  369  * The handler can be managed using le_gnss_AddPositionHandler()
  370  * and le_gnss_RemovePositionHandler().
  371  * When a position is computed, the handler is called.
  372  *
  373  * The application has to release each position sample object received by the handler,
  374  * using the le_gnss_ReleaseSampleRef().
  375  *
  376  * A sample code can be seen in the following page:
  377  * - @subpage c_gnssSampleCodePosition
  378  *
  379  * @subsection le_gnss_GetLeapSeconds Get leap seconds event information
  380  * The leap seconds event information is retrieved by calling le_gnss_GetLeapSeconds() API.
  381  * The result includes current GPS time, current leap seconds, next leap second event time,
  382  * and next leap seconds.
  383  *
  384  * Insertion of each UTC leap second is usually decided about six months in advance by the
  385  * International Earth Rotation and Reference Systems Service (IERS).

  396  * With le_gnss_LoadExtendedEphemerisFile() , you can load an 'Extended Ephemeris' file into
  397  * the GNSS device from the filesystem.
  398  * You have to download the file before loading it.
  399  * @warning Ensure to check that the downloaded file is supported for your specific platform.
  400  *
  401  * With le_gnss_GetExtendedEphemerisValidity(), you will to get the validity of the last injected
  402  * Extended Ephemeris.
  403  *
  404  * You can enable/disable the use of the 'Extended Ephemeris' file into the GNSS device with
  405  * le_gnss_EnableExtendedEphemerisFile() / le_gnss_DisableExtendedEphemerisFile() functions.
  406  * @warning Ensure to check configuration capabilities for your specific platform.
  407  * A reboot must be required if your platform doesn't allow run-time configuration.
  408  *
  409  * A sample code can be seen in the following page:
  410  * - @subpage c_gnssSampleCodeXtra
  411  *
  412  * @subsection le_gnss_Assisted_GNSS_UP 3GPP User Plane (OMA SUPL)
  413  *
  414  * That 3GPP User Plane A-GNSS (Assisted GNSS) protocol is defined by two different standardization
  415  * bodies, 3GPP and Open Mobile Alliance (OMA). For more information, please refer to the standard.
  416  *
  417  * Both MS-Assisted and MS-Based position determination methods are supported in the User Plane.
  418  *
  419  * In MS-Assisted mode, the MS (Mobile Station) measures the signals from the GNSS satellites
  420  *, then returns the retrieved GNSS data to the SUPL (Secure User Plan Location) server, where the
  421  * position calculation is performed.
  422  *
  423  * In MS-Based mode, the MS gets the assistance data from the SUPL (Secure User Plan Location)
  424  * server. The MS measures the signals from the GNSS satellites and makes the position calculation.
  425  *
  426  * The data transport over User Plan is done using the TCP/IP protocol.
  427  *
  428  * The Assisted-GNSS mode can be configured thru the le_gnss_SetSuplAssistedMode() function.
  429  *
  430  * The supported modes are the following:
  431  * - Standalone mode: That 3GPP User Plane A-GNSS feature is deactivated.
  432  * - MS-Based mode
  433  * - MS-Assisted mode
  434  *
  435  * Moreover, the le_gnss_GetSuplAssistedMode() function reads the configured Assisted-GNSS mode.
  436  *
  437  * The SUPL server is configured using the le_gnss_SetSuplServerUrl() function. That function sets
  438  * the SUPL server URL and optionally the port number.
  439  *
  440  * The SUPL certificate to be used in A-GNSS sessions is injected through the
  441  * le_gnss_InjectSuplCertificate() function and deleted through the le_gnss_DeleteSuplCertificate()
  442  * function.
  443  * The SUPL certificate lenght given as parameter to le_gnss_InjectSuplCertificate() must be less
  444  * than LE_GNSS_SUPL_CERTIFICATE_MAX_LEN.
