Mobile Device Orientation via Geodesy Network Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the orientation of mobile wireless communication devices are limited when they cannot receive or evaluate orientation signals, and existing technologies do not effectively improve orientation determination in such scenarios.
Innovation Solution
The use of network adjustment methods from geodesy, which estimate the orientation and position of mobile communication devices by utilizing relative and absolute orientation information from multiple communication devices connected at a specific point in time, even if the device cannot determine its own position or orientation signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If network adjustment methods from geodesy are used to estimate orientation and position, then orientation determination accuracy is improved even when devices cannot receive orientation signals, but device complexity increases due to requiring multiple communication devices and coordination
Solution Approach 1:
The system divides the orientation determination task into multiple segments by using multiple communication devices, where each device contributes its own orientation information and relative position data to the overall network adjustment calculation, enabling accurate orientation estimation even when individual devices cannot receive orientation signals
Solution Approach 2:
The patent introduces relative position information and observation values as intermediary data elements that mediate between the communication devices and the final orientation determination, allowing the system to indirectly determine orientation through geometric relationships rather than direct signal reception
2Reliability
If multiple communication devices are used for network adjustment, then orientation estimation reliability is improved, but loss of information increases due to requiring coordination and data exchange between multiple devices
Solution Approach 1:
The patent merges orientation information and relative position data from multiple communication devices into a unified network adjustment calculation, combining disparate data sources to achieve more reliable orientation estimation that overcomes the limitations of individual devices
3Adaptability or versatility
If network adjustment with multiple devices is implemented, then orientation determination is possible without orientation signals, but ease of operation deteriorates due to complex coordination requirements
Solution Approach 1:
The patent implements a universal orientation determination method that can operate in multiple scenarios - whether devices can receive orientation signals directly or must rely on network adjustment with relative position information, making the system adaptable to various operational conditions and device capabilities

AI summary
One aspect of the invention can be seen in the fact that, in order to determine the orientation and optionally also the position of a movable communication device (10), the orientation information and optionally also position information of at least one further movable communication device (20, 30, 40) and/or at least one static communication device, as well as at least one observation value that defines the relative orientation and/or relative position between the at least two communication devices (10, 20), are made available to the movable communication device (10) or a central device (120).Using the orientation information and position information and the observation values, network adjustment is performed in the mobile communication device (10) or the central device (120) to determine the orientation and, if necessary, the position of the mobile communication device (10).
