Engineering Contradiction Analysis
1Measurement precision
If conventional network measurement devices perform time synchronization error measurements using multi-band satellite signals, then positioning accuracy and time synchronization precision are improved, but the devices cannot quickly detect or respond to reception abnormalities in multi-band signals, leading to reduced reliability in challenging antenna environments
Solution Approach 1:
The patent implements a feedback mechanism by continuously monitoring the reception status of multi-band satellite signals and automatically detecting abnormalities. The measurement device compares expected signal characteristics with actual received signals, and when deviations are detected, it triggers alerts and can switch to alternative measurement methods, ensuring reliable operation even in challenging antenna environments.
Solution Approach 2:
The patent applies preliminary action by pre-configuring multiple GNSS satellite systems (GPS, GLONASS, Galileo, BeiDou) and their corresponding frequency bands before measurement operations begin. The device预先 establishes reception channels for L1, L2, L5 bands and sets up abnormality detection thresholds, enabling rapid response to reception issues without requiring real-time configuration changes.
2Measurement precision
If the measurement device uses multiple GNSS systems and multi-band reception to improve measurement accuracy, then the precision of time synchronization measurements is enhanced, but the device complexity increases due to the need to manage multiple frequency bands and satellite systems
Solution Approach 1:
The patent implements universality by designing a measurement device with a unified architecture that can process signals from multiple GNSS systems (GPS, GLONASS, Galileo, BeiDou) across multiple frequency bands (L1, L2, L5) through a single integrated receiver. The device uses common signal processing chains and measurement algorithms that work across all satellite systems and bands, reducing the need for separate processing paths and minimizing overall system complexity.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting reception parameters such as frequency band selection, satellite system prioritization, and signal processing thresholds based on the current measurement requirements and reception conditions. This allows the device to optimize its operation for different scenarios without requiring hardware changes, managing complexity through software-controlled parameter adaptation.
3Adaptability or versatility
If the measurement device operates in environments with uncertain GNSS antenna support and quality, then it can be deployed more widely for network assessments, but the accuracy and precision of measurements are reduced due to reception abnormalities
Solution Approach 1:
The patent implements dynamics by making the measurement device adaptable to varying antenna qualities and reception conditions through real-time monitoring and dynamic adjustment of measurement parameters. The device continuously assesses signal quality metrics and adjusts its operation accordingly, maintaining acceptable measurement precision across diverse deployment environments with uncertain antenna support.
Solution Approach 2:
The patent uses feedback mechanisms to detect reception abnormalities caused by poor antenna quality or unsupported frequency bands, and automatically compensates by adjusting measurement strategies. When degradation is detected, the system can switch to using available bands with higher confidence, apply correction algorithms, or alert operators, thereby maintaining measurement reliability despite varying antenna conditions.

AI summary
A network measurement device includes a setting control unit that sets, for example, a single GNSS as a transmission source of a signal of a multi-band, a multi-band abnormality detection unit that detects a multi-band reception abnormality based on an existing GNSS antenna receiving a signal in the multi-band transmitted from the GNSS, which is the transmission source, and reception signal information obtained by reception processing in a state in which the network measurement device is connected to the apparatus of a moving destination, for example, a boundary clock, and the existing GNSS antenna is connected to an antenna input terminal, for example, and an alert notification control unit that notifies a user of an alert notification that a multi-band reception abnormality occurs when a multi-band reception abnormality is detected.
