galileoCodes

Generate ranging codes for Galileo

Since R2026a

Syntax

[primarycode,secondarycode] = galileoCodes(svid,signaltype)

Description

[primarycode,secondarycode] = galileoCodes(svid,signaltype) generates primary and secondary ranging codes for each satellite specified in svid for the corresponding Galileo signal type specified in signaltype. The function generates ranging codes as per the Galileo standard [1].

Examples

Generate Galileo E6C Codes

Generate ranging codes for two Galileo satellites over E6c band.

Specify the satellite IDs and the signal type.

svid = [3; 15];
signaltype = "e6c";

Generate the corresponding primary and secondary codes for both the satellites.

[primarycode,secondarycode] = galileoCodes(svid,signaltype);
size(primarycode)

ans = 1×2

        5115           2

size(secondarycode)

ans = 1×2

   100     2

Input Arguments

svid — Satellite vehicle identifier number

integer in range [1, 50] | vector of integers in range [1, 50]

Satellite vehicle identifier number (SVID), specified as one of these options.

• Integer in the range [1, 50] — Specifies an SVID for a single satellite.

• Vector of integers in the range [1, 50] — Specifies SVIDs for multiple satellites.

Data Types: double

signaltype — Type of signal to generate

"E1B" | "E1C" | "E5aI" | "E5aQ" | "E5bI" | "E5bQ" | "E6B" | "E6C"

Type of signal to generate, specified as "E1B", "E1C", "E5aI", "E5aQ", "E5bI", "E5bQ", "E6B", or "E6C". The input is not case-sensitive.

Data Types: char | string

Output Arguments

primarycode — Primary ranging codes

binary-valued matrix

Primary ranging codes, returned as a binary-valued matrix of size m-by-n, where n is the number of SVIDs specified in the svid argument. The value of m depends on the signaltype argument.

signaltype Value	Value of m
"E1B" or "E1C"	4092
"E5aI", "E5aQ", "E5bI", or "E5bQ"	10230
"E6B" or "E6C"	5115

Data Types: logical

secondarycode — Secondary ranging codes

binary-valued matrix

Secondary ranging codes, returned as a binary-valued matrix of size m-by-n, where n is the number of SVIDs specified in the svid argument. The value of m depends on the signaltype argument.

signaltype Value	Value of m
"E1B" or "E6B"	0
"E1C"	25
"E5aI"	20
"E5aQ", "E5bQ", or "E6C"	100
"E5bI"	4

Data Types: logical
