Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If survey data is transmitted in real-time over network connections, then data accuracy and timeliness are improved, but system complexity and infrastructure requirements increase
Solution Approach 1:
A central computing device serves as an intermediary between multiple survey instruments and authorized user devices. This mediator receives survey measurement data from instruments, processes it through real-time kinematic calculations, and distributes results to authorized users, thereby improving data accuracy while managing system complexity centrally rather than distributing it across all components
Solution Approach 2:
Multiple survey instruments are merged into a single networked system that transmits data to a central computing device. This consolidation allows real-time data processing and sharing across the network, improving measurement precision through combined data while reducing individual device complexity requirements
2Loss of time
If real-time transmission of survey data is implemented, then data timeliness and operational efficiency are improved, but network dependency and potential data loss risks increase
Solution Approach 1:
The system establishes feedback loops where survey measurement data is transmitted in real-time to the central computing device, which processes the data and sends corrections back through the network. This continuous feedback mechanism reduces data transmission delays by maintaining constant communication channels while allowing for error detection and correction, thereby improving both timeliness and reliability
Solution Approach 2:
The system performs preliminary actions by establishing network connections and data transmission protocols before survey operations begin. Virtual reference station correction data is obtained in advance, and real-time kinematic calculation parameters are pre-configured, ensuring that when data transmission occurs, the infrastructure is already in place to handle it reliably with minimal delay
3Measurement precision
If virtual reference station correction data is incorporated, then survey measurement accuracy is improved, but processing complexity and computational requirements increase
Solution Approach 1:
The central computing device acts as an intermediary that handles the complex processing of virtual reference station correction data. It receives raw survey measurement data, applies real-time kinematic calculations with correction data, and produces accurate results, thereby improving measurement precision while containing processing complexity within the central system rather than requiring complex processing at each instrument or user device
Solution Approach 2:
The system creates copies of survey measurement data and correction data that are distributed across the network to the central computing device for processing. This allows multiple instruments to contribute data simultaneously without each instrument needing to perform complex calculations, improving accuracy through aggregated data while keeping individual device complexity low

AI summary
A method for providing user interactive actual time networked surveying is disclosed. In one embodiment, a network connection is established between a survey instrument and a central computing device. In addition, a user session is established with the central computing device. Survey measurement data obtained with the survey instrument is transmitted to the central computing device. In addition, correction data from a virtual reference station (VRS) is received at the central computing device. The user session is allowed to direct the processing of the received survey measurement data including one or more real time kinematic calculations at the central computing device. The output of the processing of the received survey measurement data is provided to one or more authorized devices having a connection to the central computing device, the output provided in a concrete and tangible format.
