This library contains routines for:

• Solving geodetic problems (C#/Rust/Matlab)
• Solving TDOA & TOA positioning/navigation problems in 2D & 3D (C#/Rust/Matlab)
• Algorithms for Virtual Long Baseline positioning (C#)

• Known times of arrival to/from base points with known locations
• Known target depth
  
  Calculated residual function:
  
  Residual function and estimated target location:

If this repository achieves:

• DONE! 25 stars - we'll add partial implementation in MATLAB (Ok, I have uploaded Matlab version on 20 stars =)
• 50 stars - we'll add AoA (Angle of arrival) estimation routines
• 100 stars - we'll add C implementation of the library
• 150 stars - we'll add complete documentation for the library

23-JAN-2020 Update:

• Added partial implementation of the library in Matlab
  To test the functionality, please, use:

• TOA & TDOA localisation demo script
• Geodetic problems: Haversine vs. Vincenty demo
• Library tests

30-NOV-2019 Update:

• Added partial implementation of the library in Rust:

• All the functionality from Algorithms.cs & from Navigation.cs

22-NOV-2019 Update:

• In GeoPoints.cs new classes for metric point (MPoint and MPoint3D)
• In Navigation.cs new methods for calculating centroids of clouds of MPoint and MPoint3D, converting between local and geographic coordinate systems, methods for calculating statistics (CEP, SEP, STD, MRSE, DRMS)

26-AUG-2019 Update:

• Routines for VLBL (Virtual long baseline) positioning
• TDOA solution in 3D
