Device Positioning

This section provides information on device positioning. If your device has positioning capabilities, the reported positioning data will be parsed and displayed. Currently, Developer Center can parse Global Positioning System (GPS), Location Based Service (LBS), and Wireless Fidelity (WIFI) positioning data using triangulation based on wireless router signal.

Prerequisites

● A product has been created.
● A device that supports the positioning feature has been connected to Developer Center successfully.
● Positioning data has been reported.

Steps

Log in to Developer Center, click "Device Management"→ "Device Maintenance” from the left-hand navigation bar to display the list of devices. Find the device you want to view and click "View" in the Action column to enter "Device Information" page, and then click "Location" tab to view location-related data for the device.

Parameters

Parameter	Description
Positioning Time	The most recent time when the positioning data was reported
Number of Visible Satellites	When the positioning data is GPS, the number of satellites currently in view for positioning may be reported.
Positioning State	Differential Positioning: A satellite signal receiver (Satellite Ground Station) is at a fixed position, enabling it to calculate satellite positioning error. The handheld receiver uses the satellite signals to calculate coordinates, which are then refined by synthesizing the positioning error data provided by the ground station, resulting in improved accuracy. Non-differential Positioning: A single receiver is used for positioning to get the absolute coordinates of the receiver antenna. Valid Positioning: Accurate information such as latitude and longitude have been obtained. Invalid Positioning: Invalid latitude and longitude, speed and direction information has been obtained. Estimating: indicates an approximate estimate of the current location information and positioning state.
Positioning Method	GNSS: Global Navigation Satellite System; GPS: Global Positioning System (United States); GL: GLONASS (Russia); GA: Galileo (European Union); BD/PQ: Navigation Satellite System (China); LBS: Location Based Services; WIFI: A location tracking system based on wireless router signal
Longitude and Latitude	The latitude and longitude reported based on WGS-84 coordinate system
