## What is GPS Relay?

Your Wi‑Fi‑only iPad has no GPS of its own. In flight, without Wi‑Fi, your EFB loses ownship. Your iPhone has a real GPS receiver — GPS Relay sends its position to your iPad over Bluetooth, and your flight app shows it as a GPS device.

NO EXTRA HARDWARE
• No hotspot, no cables, no external GPS box.
• Works in airplane mode, as long as Bluetooth stays on.
• Everything stays on your two devices. Nothing goes over the internet.

WORKS WITH YOUR FLIGHT APP
GPS Relay feeds the iPad like a GDL 90 compatible GPS receiver, on the iPad itself:
• ForeFlight — nothing to set up.
• Jeppesen FliteDeck Pro — switch on its GDL90 Compatible Device input (port 4000).
• Other EFBs that accept a GDL 90 device on UDP port 4000.

SET UP IN TWO MINUTES
A step-by-step guide on each device: allow Bluetooth and location, check that both screens show the same 4-letter code, put the iPhone at a window. Done.

SET AND FORGET
• The iPhone keeps relaying with the screen locked; the iPad keeps feeding your EFB in the background.
• Preflight checklist on both devices: what's ready turns green.
• Honest accuracy: your EFB gets the iPhone's real accuracy, so it can hide ownship when GPS is too weak.
• Alerts if the link drops or the iPhone loses GPS (for example when it is away from a window).
• STOP switches GPS, Bluetooth and background activity completely off.

FREE TO START
Your first 2 hours of relay time are free, counted only while your iPad actually receives GPS. After that, unlock GPS Relay once with an in‑app purchase — no subscription. One purchase covers your iPhone and iPad (same Apple ID); the iPad side never needs it.

WHAT YOU NEED
• An iPhone (the GPS source) and an iPad, both with GPS Relay installed.
• Bluetooth on both. Keep the iPhone at a window: the airplane's skin blocks GPS.

IMPORTANT
GPS Relay is for situational awareness only. It is not certified and must not be used as a primary means of navigation. Follow your operator's procedures and regulations for portable electronic devices.
