I will analyze gnss rtk data and positioning accuracy


About this gig
Do you have GNSS / GPS / RTK data but need help understanding its accuracy, quality, or performance?
I provide practical GNSS data analysis based on real-world development and field experience.
I can help with:
GNSS / GPS / RTK log analysis
NMEA, CSV, and SBF data processing
RTK FIX / FLOAT status analysis
Positioning accuracy and error evaluation
Trajectory mapping and visualization
Horizontal / vertical error analysis
Dataset and condition comparisons
Custom Python-based processing
Graphs, maps, and technical summaries
From 2023 to 2025, I worked on the development and implementation support of RTK-GNSS software applications at NTT East, one of Japan's major telecommunications companies. My experience includes software development, field testing, positioning accuracy evaluation, and supporting real-world use of RTK technology.
I am also involved in applied research and technical paper writing related to positioning technologies.
My goal is not just to create graphs, but to help you understand what your GNSS data actually means.
Please contact me before ordering for complex datasets, moving-base RTK, proprietary formats, or custom analysis requirements.

FAQ
What GNSS data formats can you analyze?
I can work with common formats such as NMEA, CSV, and SBF, as well as other structured GNSS datasets. If you use a proprietary or uncommon format, please contact me before ordering so I can confirm compatibility.
Can you analyze RTK FIX and FLOAT performance?
Yes. If the required status information is available in your data, I can analyze FIX/FLOAT ratios, positioning behavior, accuracy, errors, and changes over time.
Can you compare multiple receivers, antennas, or test conditions?
Yes. I can compare multiple datasets, receivers, antennas, positioning methods, or environmental conditions. For larger comparison studies, please contact me first for a custom offer.
What do I need to provide before the analysis?
Please provide your GNSS log files, information about the receiver and test setup, and the objective of the analysis. If accuracy evaluation is required, please also provide a known reference position or reference dataset when available.
Will I receive the Python analysis code
Analysis results, graphs, maps, and summaries are included according to your package. Python source code can also be provided when included in the package or purchased as an additional service.
