GNSSSignals.jl

A Julia package for generating GNSS spreading codes and signals.

Features

• GPS L1 (BPSK)
• GPS L5 (BPSK with Neuman-Hofman secondary code)
• Galileo E1B (CBOC modulation)
• Highly optimized code generation using fixed-point arithmetic for real-time signal processing

Installation

julia> ]
pkg> add GNSSSignals

Quick Start

using GNSSSignals
using Unitful: MHz

gpsl1 = GPSL1()
prn = 1

# Generate 1 ms of sampled code at 4 MHz
sampled_code = gen_code(4000, gpsl1, prn, 4MHz)

# For repeated calls, use the in-place version
buffer = zeros(Int16, 4000)
gen_code!(buffer, gpsl1, prn, 4MHz)
