multilat-solver 1.1.1

Universal MultiLateration Localization System with flexible input/output adapters

MultiLat Localizer

Universal multilateration localization with pluggable input/output adapters for distance measurements and position output.

Features

• Inputs: Serial (UWB/RTK-DW1000), MQTT, UDP, File; custom adapters via with_input()
• Outputs: MAVLink, MAVROS (ROS2), UDP, File, Console; multiple outputs at once, custom adapterd via 'with_output()'
• Calibration: None, Linear, Quadratic, Cubic;
• GPS: ENU → GPS via pymap3d; frequency throttling; message type (GPS / Position / Both)
• Config: Python API only (no config files)

Installation

pip install multilat_solver

Optional: pip install multilat_solver[mqtt] (MQTT), multilat_solver[ros2] (ROS2), .[dev] (development).

Examples

• examples/send_data.py + examples/for_docs.py — UDP distance simulator + localizer (run send_data first, then for_docs); see Quick Start
• examples/basic_usage.py — Serial in, console/file/MAVLink out
• examples/multi_output.py — Multiple outputs
• examples/mavlink_input_with_sim.py — MAVLink distances in + simulator
• examples/uavcan_input_mavlink_output.py — Custom UAVCAN input → MAVLink out
