Skyty

Product Introduction

1. Definition: Skyty is a specialized mobile aviation telemetry instrument designed for the iOS ecosystem. It functions as a standalone, offline flight tracking application that utilizes the iPhone’s internal Global Positioning System (GPS) receiver to provide real-time aeronautical data without the need for cellular connectivity or inflight WiFi.

2. Core Value Proposition: Skyty exists to solve the "information blackout" experienced by passengers on commercial flights where inflight entertainment systems are unavailable or internet access is prohibitively expensive. By leveraging on-device NASA terrain datasets, Skyty provides high-precision flight data—including Altitude Above Ground (AGL), ground speed, and geographic positioning—maintaining a 100% private, data-sovereign environment for the user.

Main Features

1. NASA-Powered Altitude Above Ground (AGL) Calculation: Unlike standard GPS apps that only provide altitude relative to sea level, Skyty integrates offline NASA elevation data (Digital Elevation Models). By cross-referencing the user’s horizontal coordinates with these local terrain heightmaps on-device, the app calculates the actual clearance between the aircraft and the ground below.

2. Autonomous GPS Telemetry Engine: The application is engineered to interface directly with the iPhone’s GNSS (Global Navigation Satellite System) chips. This allows for the precise tracking of Ground Speed (GND SPD) in kilometers per hour or knots, Heading, and Latitude/Longitude coordinates. Because GPS is a receive-only technology, it functions natively in Airplane Mode, bypassing the need for active radio transmissions or network handshakes.

3. Regional Offline Map Infrastructure: Skyty utilizes a modular data architecture where users can pre-download comprehensive region packs (e.g., Europe, approximately 300 MB). These packs contain vector map data and topographical information, ensuring that the flight path, coastal outlines, city boundaries, and mountain ranges remain visible on the moving map interface throughout the duration of a flight without any external data requests.

4. Privacy-Centric Flight Recording: For Pro users, Skyty offers flight path recording. All telemetry logs are stored locally on the iPhone’s secure enclave. The app operates under a zero-telemetry policy—no analytics, no account requirements, and no cloud syncing—ensuring that the user’s travel history remains entirely confidential.

Problems Solved

1. Pain Point: Expensive or Unreliable Inflight WiFi: Many airlines charge premium rates for internet access, and satellite-based WiFi often suffers from high latency or disconnects. Skyty eliminates the dependency on external networks by processing all flight metrics locally.

2. Pain Point: Inaccurate GPS Altitude Reporting: Standard GPS altitude (MSL) does not tell a passenger how close they are to the mountains or terrain below. Skyty’s use of NASA terrain data solves this by providing a context-aware altitude (AGL).

3. Target Audience: The primary user base includes "AvGeeks" (aviation enthusiasts), frequent business travelers, window-seat passengers who enjoy geography, and tech-savvy travelers concerned about data privacy and tracking.

4. Use Cases: Skyty is essential for identifying landmarks during transcontinental flights, monitoring aircraft performance (speed and altitude) during different phases of flight, and keeping track of the estimated time of arrival (ETA) to the destination when the cabin monitors are turned off.

Unique Advantages

1. Differentiation: Most flight trackers rely on ADS-B data via the internet (like FlightRadar24). Skyty is fundamentally different because it does not "track" the plane via a database; it treats the iPhone as a primary flight instrument that calculates the flight state independently of the aircraft's own systems.

2. Key Innovation: The specific implementation of offline NASA elevation data on a consumer mobile device is the core innovation. This turns a standard smartphone into a sophisticated altimeter capable of terrain-awareness, a feature usually reserved for professional glass cockpit avionics.

Frequently Asked Questions (FAQ)

1. Does GPS work in Airplane Mode on an iPhone? Yes, GPS is a passive satellite-based positioning system that does not require cellular or WiFi signals. As long as Location Services are enabled in the iOS settings, Skyty can receive signals from GPS satellites through the aircraft window even while the phone is in Airplane Mode.

2. How does Skyty calculate altitude above ground without an internet connection? Skyty uses pre-downloaded terrain elevation packs based on NASA data. Before your flight, you download the map for your specific region. During the flight, the app takes your GPS coordinates and subtracts the ground elevation (from its internal database) from your GPS altitude to determine your real height above the terrain.

3. Is there a subscription fee for Skyty? Skyty offers a "Freemium" model. The basic version includes live position, speed, and GPS altitude for free. The Pro version, which unlocks Altitude Above Ground (AGL), flight recording, and all regional terrain packs, is available for a low annual fee, providing a cost-effective alternative to expensive one-time-use inflight WiFi passes.
