Numpytrila

Numpytrila is an open‑source Python library that builds on the functionality of NumPy to provide specialized tools for trilateration and related geometric computations. First released in 2022, the package targets developers and researchers who need to solve position‑finding problems using distance measurements, such as in robotics, sensor networks, and geolocation applications. Numpytrila integrates tightly with NumPy’s array structures, allowing users to perform trilateration calculations on large datasets with the same performance characteristics as standard NumPy operations.

Key features of Numpytrila include functions for linear and nonlinear trilateration, support for both two‑dimensional and three‑dimensional spaces, and utilities for handling noisy distance data through least‑squares optimization and robust statistical methods. The library also offers tools for converting between coordinate systems, visualizing intermediate results with Matplotlib, and batch processing of multiple trilateration problems in parallel using NumPy’s broadcasting capabilities.

Documentation is provided on the project’s website and includes API references, example notebooks, and tutorials that illustrate common use cases such as indoor positioning, acoustic source localization, and satellite‑based ranging. The source code is hosted on GitHub under the permissive BSD‑3‑Clause license, encouraging both academic and commercial adoption. Contributions are accepted via pull requests, and the development workflow follows standard continuous‑integration testing with NumPy’s test suite to ensure compatibility across Python 3.8 and newer versions.

Since its inception, Numpytrila has been adopted by several research groups and incorporated into open‑source toolkits for autonomous navigation and Internet of Things (IoT) positioning. Ongoing development focuses on expanding algorithmic options, improving numerical stability, and adding support for GPU‑accelerated computation through compatible back‑ends.
