This parameter specifies the longitude of the device's position in degrees, multiplied by 1 million. The positive value signifies the direction, east of the prime meridian. The negative value signifies the direction, west of the prime meridian. Range is from: 180d00.00' West (-180,000,000) to 180d00.00' East (180,000,000). Example: A longitude of 13d19.43' E would be represented as 13,323,833, derived as (13*1,000,000)+((19.43*1,000,000)/60). A longitude of 50d00.00' W would be represented as value -50,000,000. This value is retained across reboots and is only reset after another scan completes successfully or GPSReset is set to true. If a scan has never succeeded before, an empty value is reported. The value of this parameter is persistent in NVRAM. TR-069/TR-181 reference: Device.FAP.GPS.LockedLongitude.
