About

GPS2Quantum

This app transforms real-time GPS coordinates into quantum spherical coordinates, visualizing your position as a state vector on a Bloch sphere. Explore two modes: real-world tracking or superposition with a chosen origin. Analyze sessions with AI and export data for further study.

Highlights
  • Real-time GPS to quantum coordinates
  • Bloch sphere visualization
  • Superposition mode with custom origin
  • AI session analysis
  • Session logging and CSV export
  • Adjustable sensor degradation

GPS2Quantum Your location is not just a latitude and longitude. It is a quantum state. GPS2Quantum transforms your real-time GPS coordinates into quantum spherical coordinates (polar angle, azimuthal angle, and radial magnitude) and visualizes your position as a state vector on a Bloch sphere. The same mathematical framework used in quantum information science, applied to where you are standing right now. TWO MODES... REAL WORLD: Capture your current GPS position and watch your quantum state vector update in real time. Track your movement across the Bloch sphere. Log every reading. Export your session as a CSV. SUPERPOSITION: Choose any location on Earth as your quantum origin. K2. The Mariana Trench. The Eiffel Tower. Your movement deltas are then applied to that origin, placing your quantum state simultaneously at your physical location and your chosen point on Earth. Your state vector moves. Your quantum position is real. THE BLOCH SPHERE 3D... Watch your quantum state vector update live. Orange trail dots trace your recent history. The STATE indicator shows whether you are in GROUND or EXCITED determined by whether your polar angle θ crosses π/2. Cross the equatorial plane and your state flips. This is not a simulation. AI SESSION ANALYSIS After collecting readings, tap the AI button for a technical analysis of your session: quantum state evolution, sensor performance, movement analysis, notable observations. In Superposition mode, a fifth section narrates your quantum journey through the origin location: the streets or sea or air you passed through, the altitude above or below the surface, the neighborhoods your quantum state traversed. SESSION LOG & EXPORT Every reading is logged with full quantum coordinates, GPS position, deltas, and uncertainty radius. Export as CSV for further analysis in any spreadsheet application. ADVANCED SETTINGS Model real-world sensor degradation with easy-to-set Drift parameters. Choose your sensor class (Consumer through Strategic Grade) and operational condition (Static, Automotive, Aerial, Subsea). The uncertainty radius visualizes as a halo ring on both the Bloch sphere and the GPS map. Set a custom altitude to anchor your quantum origin underground, subsea, or in near-space. WHO IS THIS FOR Physicists, geodesists, engineers, and anyone curious about where quantum mechanics and physical location intersect. GPS2Quantum does not simplify the physics. It applies it. Location is a quantum state. SUBSCRIPTION Requires a subscription. Download is free with a trial (Monthly: 7 days, Annual: 14 days). After the trial, subscriptions auto-renew unless canceled.

About

NMEA Send Location

Features
Read full description

This application sends GPS coordinates, current speed, course over ground and heading via WiFi, Bluetooth, USB using NMEA 0183 protocol. It can replace a USB GPS receiver. Features: - Supports NMEA 0183 messages: GPGGA, GPRMC, GPVTG, GPHDM/GPHDT; - Sends messages based on a timer; - Reconnects after a lost connection; - Shows the last sent coordinates. NMEASendLocation reads geo data from your iPhone/iPad, forms NMEA 0183 messages based on this data and transmits them to navigation software (OpenCPN, SignalK server, etc.) running on a computer, using Bluetooth, WiFi or USB. Data is transmitted over the network via UDP.

Verdict

The call

The clearest difference is in-app purchases: NMEA Send Location at none against GPS2Quantum's 2. GPS2Quantum's advantage is update cadence (weekly vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
