Vps2Location

↳ inherits from _LocationEssentials.CLLocation

Declaration

final class Vps2Location

Summary

A CLLocation subclass representing a position computed by VPS2. MSL altitude is not available from VPS2 without a geoid model conversion, so altitude always returns -1. Use ellipsoidalAltitude for the WGS84 height computed by VPS2, and verticalAccuracy (≥ 0) for its precision.

Constructors

Constructor

required init?(coder: NSCoder)

Overload

init(coordinate: CLLocationCoordinate2D, ellipsoidalAltitude: CLLocationDistance, horizontalAccuracy: CLLocationAccuracy, verticalAccuracy: CLLocationAccuracy, timestamp: Date = Date())

Summary

Creates a Vps2Location from VPS2-computed position data.

Properties

Name	Type	Summary
override var altitude	CLLocationDistance	Always `-1`. MSL altitude is not available from VPS2; use `ellipsoidalAltitude` instead.
override var ellipsoidalAltitude	CLLocationDistance	The WGS84 ellipsoidal altitude computed by VPS2, in metres.
override class var supportsSecureCoding	Bool	-
override var verticalAccuracy	CLLocationAccuracy	Accuracy of `ellipsoidalAltitude`, in metres. A negative value indicates invalid.
