   19  *
   20  * This API provides access to the device's physical position and movement information.
   21  *
   22  * @note    Enabling and disabling the positioning system is a privileged operation available
   23  *          only through the @ref c_posCtrl.
   24  *
   25  * @section le_pos_binding IPC interfaces binding
   26  *
   27  * All the functions of this API are provided by the @b positioningService application service.
   28  *
   29  * Here's a code sample binding to Positioning services:
   30  * @verbatim
   31    bindings:
   32    {
   33       clientExe.clientComponent.le_pos -> positioningService.le_pos
   34    }
   35    @endverbatim
   36  *
   37  * @section le_pos_fix Fix On Demand
   38  * The @c le_pos_Get2DLocation() function gets the last updated latitude, longitude
   39  * and the horizontal accuracy values:
   40  *
   41  * - latitude is in degrees, positive North.
   42  * - longitude is in degrees, positive East.
   43  * - horizontal accuracy is in meters by default.
   44  *
   45  * The latitude and longitude are given in degrees with 6 decimal places like:
   46  * - Latitude +48858300  = 48.858300 degrees North
   47  * - Longitude +2294400 =  2.294400 degrees East
   48  *
   49  * The @c le_pos_Get3DLocation() function gets the last updated latitude, longitude,
   50  * altitude and their associated accuracy values.
   51  * - altitude is in meters by default, above Mean Sea Level, with 3 decimal places
   52  * (3047 = 3.047 meters).
   53  * - horizontal and vertical accuracies are in meters by default.
   54  *
   55  * The @c le_pos_GetTime() function gets the time of last updated position:
   56  * - Hours into the day [range 0..23].
   57  * - Minutes into the hour [range 0..59].
   58  * - Seconds into the minute [range 0..59].
   59  * - Milliseconds into the second [range 0..999].
   60  *
   61  * The @c le_pos_GetDate() function gets the date of last updated position:
   62  * - Year A.D. [e.g. 2014].
   63  * - Month into the year [range 1...12].
   64  * - Days into the month [range 1...31].
   65  *
   66  * The @c le_pos_GetMotion() function gets the last updated horizontal and vertical
   67  * speed values and the associated accuracy values:
   68  * - horizontal speed is in m/sec.
   69  * - vertical speed is in m/sec, positive up.
   70  *
   71  * The @c le_pos_GetHeading() function gets the last updated heading value in degrees and
   72  * its associated accuracy value:
   73  *  - Heading in degrees, ranges from 0 to 359, 0 being True North.
   74  * Heading is the direction that the vehicle or person is facing.
   75  *
   76  * The @c le_pos_GetDirection() function gets the last updated direction value in degrees and
   77  * its associated accuracy value:
   78  *  - Direction in degrees, ranges from 0 to 359, 0 being True North.
   79  * Direction of movement is the direction that the vehicle or person is actually moving.
   80  *
   81  * The @c le_pos_GetFixState() function gets the position fix state. The fix state allows the user
   82  * to determine if it is a 2-Dimensional or a 3-Dimensional position fix.
   83  *
   84  * The @c le_pos_SetDistanceResolution() function sets the resolution for the positioning distance
   85  * values.
   86  *
   87  * A sample code can be seen in the following page:
   88  * - @subpage c_posSampleCodeFixOnDemand
   89  *
   90  * @section le_pos_navigation Navigation
   91  * To be notified when the device is in motion, you must register an handler function
   92  * to get the new position's data. The @c le_pos_AddMovementHandler() API registers
   93  * that handler. The horizontal and vertical change is measured in meters so only movement over
   94  * the threshhold will trigger notification (0 means we don't care about changes).
   95  *
   96  * The handler will give a reference to the position sample object that has triggered the
   97  * notification. You can then access parameters using accessor functions, and release
   98  * the object when done with it.
   99  *
  100  * The accessor functions are:
  101  * - le_pos_sample_Get2DLocation()
  102  * - le_pos_sample_GetDate()
  103  * - le_pos_sample_GetTime()
  104  * - le_pos_sample_GetAltitude()
  105  * - le_pos_sample_GetHorizontalSpeed()
  106  * - le_pos_sample_GetVerticalSpeed()
  107  * - le_pos_sample_GetHeading()
  108  * - le_pos_sample_GetDirection()
  109  * - le_pos_sample_GetFixState()
  110  *
  111  * @c le_pos_sample_Release() releases the object.
  112  *
  113  * You can uninstall the handler function by calling the le_pos_RemoveMovementHandler() API.
  114  * @note The le_pos_RemoveMovementHandler() API does not delete the Position Object. The caller has
  115  *       to delete it by calling the le_pos_sample_Release() function.
  116  *
  117  * A sample code can be seen in the following page:
  118  * - @subpage c_posSampleCodeNavigation
  119  *
  120  * @section le_pos_acquisitionRate Positioning acquisition rate
  121  *
  122  * The acquisition rate value can be set or get with le_pos_SetAcquisitionRate() and
  123  * le_pos_GetAcquisitionRate().
  124  * It is also set when calling le_pos_AddMovementHandler(). The acquisition rate is calculated
  125  * from the horizontal and vertical magnitude parameters set in this function.
  126  * This calculated acquisition rate can be retrieved by calling le_pos_GetAcquisitionRate().
  127  * @note
  128  * The acquisition rate set will take effect once a request of activation of the positioning service
  129  * by le_posCtrl_Request() is done.
  130  * @note
  131  * If the acquisition rate was not previously configured, it will be set to a default value
  132  * of one second once le_posCtrl_Request() is called.
