Vps2GeolocationData

Location and heading data calculated by VPS2.

Declaration

struct Vps2GeolocationData

Properties

Name	Type	Summary
var clHeading	CLHeading	The heading represented as a `CLHeading` (via `Vps2Heading`). `trueHeading` is the VPS2-computed heading in degrees clockwise from true north. `headingAccuracy` is derived from `rotationAccuracyDeg`. The magnetometer component values (`x`, `y`, `z`) are zero because VPS2 does not use a magnetometer.
var clLocation	CLLocation	The position represented as a `CLLocation` (`Vps2Location`). `coordinate` and `horizontalAccuracy` carry the VPS2-computed values. `ellipsoidalAltitude` holds the WGS84 height from VPS2; `verticalAccuracy` is its precision. - Note: `altitude` (MSL/orthometric) always returns `-1` because converting WGS84 ellipsoidal height to MSL requires a geoid model (e.g. EGM96) that is not currently available. Use `ellipsoidalAltitude` instead.
var debugDescription	String	A textual representation of this instance, suitable for debugging. Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the `String(reflecting:)` initializer. This initializer works with any type, and uses the custom `debugDescription` property for types that conform to `CustomDebugStringConvertible`: struct Point: CustomDebugStringConvertible { let x: Int, y: Int var debugDescription: String { return "(\(x), \(y))" } } let p = Point(x: 21, y: 30) let s = String(reflecting: p) print(s) // Prints "(21, 30)" The conversion of `p` to a string in the assignment to `s` uses the `Point` type's `debugDescription` property.
var geolocationData	GeolocationData	Contains the GPS and heading data.
var horizontalAccuracyMetres	Float	Horizontal accuracy in metres.
var rotationAccuracyDeg	Float	Rotation accuracy in degrees.
let timestamp	Date	The time at which this geolocation was acquired.
var trackingState	Vps2TrackingState	The state of VPS2 tracking. The other fields in this struct are only valid if the tracking state is not .unavailable.
var verticalAccuracyMetres	Float	Vertical accuracy in metres.
