STRUCT

WpsLocation

public struct WpsLocation: CustomStringConvertible

Contains world positioning data from the WPS (World Positioning System).

WpsLocation provides global positioning information that combines GPS/GNSS data with visual positioning for enhanced accuracy and reliability.

Overview​

WPS location data includes:

  • Reference GPS coordinates (latitude, longitude, altitude)
  • Transformation matrix for coordinate conversions
  • Status information about positioning quality

Example Usage​

let (status, location) = wpsSession.latestLocation()
if status.isOk() {
    print("GPS Coordinates: \(location.referenceLatitudeDegrees), \(location.referenceLongitudeDegrees)")
    print("Altitude: \(location.referenceAltitudeMetres) meters")
    print("Status: \(location.status)")
    
    // Use the transformation matrix for coordinate conversions
    let worldPosition = location.trackingToRelativeEdn
    placeARContent(at: worldPosition)
}

Properties​

referenceLatitudeDegrees​

public let referenceLatitudeDegrees: Double

Reference latitude in degrees (WGS84 coordinate system).

This represents the GPS latitude of the reference point used for WPS positioning calculations.

referenceLongitudeDegrees​

public let referenceLongitudeDegrees: Double

Reference longitude in degrees (WGS84 coordinate system).

This represents the GPS longitude of the reference point used for WPS positioning calculations.

referenceAltitudeMetres​

public let referenceAltitudeMetres: Double

Reference altitude in meters above sea level.

This represents the GPS altitude of the reference point used for WPS positioning calculations.

trackingToRelativeEdn​

public let trackingToRelativeEdn: simd_float4x4

Transformation matrix from tracking to relative coordinate system.

This 4x4 transformation matrix converts between the tracking coordinate system and the relative coordinate system used for AR content placement.
