A Swift package to compute satellite positions from two-line elements (TLE), wrapping the sgp4lib library (by Daniel Warner)
import SGPKit
let title = "ISS (ZARYA)"
let firstLine = "1 25544U 98067A 13165.59097222 .00004759 00000-0 88814-4 0 47"
let secondLine = "2 25544 51.6478 121.2152 0011003 68.5125 263.9959 15.50783143834295"
// Instantiate a new TLE descriptor
let tle = TLE(title: title, firstLine: firstLine, secondLine: secondLine)
// Instantiate the interpreter
let interpreter = TLEInterpreter()
// Obtain the data
let data: SatelliteData = interpreter.satelliteData(from: tle, date: .now)
print(data.latitude)
print(data.longitude)
print(data.altitude)
print(data.speed)If you want to use SGPKit in any other project that uses SwiftPM, add the package as a dependency in Package.swift:
dependencies: [
.package(
url: "https://github.com/csanfilippo/swift-sgp4",
from: "1.2.0"
),
