r-multilateration-lib

Overview

The r-multilateration-lib is a set of R scripts designed for multilateration calculations. It provides functions to determine the position of a point based on distances from known reference points.

Usage Example

See example.R for a demonstration:

# Source the core multilateration code
source("R/multilateration.R")
source("R/utils.R")

# Define reference points (anchors) and measured distances
anchors <- data.frame(
  x = c(0, 0, 10, 10),
  y = c(0, 10, 0, 10)
)
distances <- c(6, 6.151, 8, 8)

# Estimate the unknown location
result <- multilaterate(distances, as.matrix(anchors))
print(result)

# Visualize anchors and estimated location
plot(anchors$x, anchors$y, col="red", pch=19, xlim=c(-2, 12), ylim=c(-2, 12), xlab="X", ylab="Y", main="Multilateration Example")
points(result[1], result[2], col="blue", pch=19)
legend("topright", legend=c("Anchors", "Estimated Location"), col=c("red", "blue"), pch=19)

File Structure

• R/multilateration.R – Main multilateration function
• R/utils.R – Utility functions for distance and validation
• example.R – Example usage and visualization

How It Works

1. Define anchor/reference points and measured distances.
2. Call multilaterate() with your data.
3. Visualize results using base R plotting.
