How SpeedProof's Compass & Navigation Works: A Technical Explanation

?? Protected Innovation

SpeedProof's hybrid navigation technology is protected under Provisional Patent Approval (Speed-Proof.com). This unique approach to combining GPS positioning with compass guidance represents innovative technology in mobile navigation.

?? Compass Mode: How Your Phone Finds North

The Technology Behind It

Your smartphone contains two key sensors that work together to create a digital compass:

• Magnetometer – Detects Earth's magnetic field (like a traditional compass)
• Accelerometer – Measures gravity and device orientation

How It Works Without GPS

• The magnetometer senses Earth's magnetic field to determine magnetic north
• The accelerometer tells the phone which way is "down" (gravity)
• By combining these readings, your phone calculates true north and your exact orientation
• No internet or GPS required – works completely offline using only built-in sensors

Technical Capabilities

• Accuracy: ±1–3 degrees under ideal conditions
• Update rate: 10–60 times per second
• Power usage: Very low (sensors are energy-efficient)
• Reliability: Works anywhere with Earth's magnetic field

?? Return to Start Navigation: The Hybrid System

How We Guide You Back

This feature combines GPS positioning with compass navigation:

Phase 1: GPS Recording (Requires GPS)

• GPS records your exact starting coordinates (latitude/longitude)
• This creates your "home base" – typically accurate within 3–10 meters
• GPS is only needed initially to set your starting point

Phase 2: Compass Navigation (Works Without GPS)

1. Current GPS position is compared with your recorded start position
2. The app calculates:
   • Bearing: The compass direction to travel (0–360°)
   • Distance: How far you are from the start point
3. Your phone's compass continuously guides you toward that bearing

Why This Works Offline

• Once the bearing is calculated, you only need the compass to maintain direction
• Think of it like: “Walk at 245° until you arrive”
• The compass keeps you on course while the distance decreases as you approach

?? Emergency GPS: Instant Location Sharing

How the Emergency GPS Button Works

1. GPS immediately captures your exact coordinates (latitude/longitude)
2. Elevation data is recorded from your phone's barometer/GPS
3. Timestamp is automatically added
4. Accuracy rating shows how precise the location is

What Information is Shared

?? EMERGENCY GPS LOCATION
EXACT COORDINATES:
Latitude: 40.7128° N
Longitude: 74.0060° W
Elevation: 85 meters
Accuracy: ±5 meters
Timestamp: [Current date/time]
  

How Sharing Works

• No automatic transmission – your location is NOT automatically sent to anyone
• You control sharing – choose how to share (text, email, messaging apps)
• Multiple formats – coordinates provided in decimal degrees for universal compatibility
• Professional rescue ready – format compatible with search and rescue teams

Technical Capabilities

• Works offline – GPS coordinates are captured without cellular service
• Multiple sharing options – use any app on your phone to share
• Universal compatibility – coordinates work with all mapping systems
• Battery efficient – single quick GPS reading (not continuous tracking)

Privacy & Safety

• You control when and with whom to share your location
• No data is stored on external servers
• One-time use – each press generates a fresh location reading
• Professional format – designed for emergency services and rescue teams

?? Your Phone's Built-in Capabilities

• GPS/GNSS: Global positioning (needed for initial coordinates)
• Magnetometer: Digital compass functionality
• Accelerometer: Orientation and tilt detection
• Gyroscope: Rotation and angular velocity
• Barometer: Altitude and elevation (in some devices)

How SpeedProof Uses These

• GPS: Records your starting position
• Compass: Provides continuous direction guidance
• Accelerometer: Ensures compass readings are accurate
• CPU: Calculates bearing and distance in real-time
• Barometer: Provides elevation data for emergency GPS
