Indoor Navigation App
BLE beacon-based indoor positioning and navigation
// Built with
swift Core Bluetooth BLE Beacons MapKit uikit01 Problem
A logistics client needed indoor navigation capabilities where GPS signals are unavailable. The system required accurate indoor positioning using BLE beacons, with real-time location tracking and turn-by-turn navigation through complex indoor environments.
03 Solution
Built an iOS app using Core Bluetooth for BLE beacon triangulation and indoor map rendering. Implemented signal strength-based positioning algorithms with beacon triangulation, custom indoor map overlays, and turn-by-turn navigation for indoor spaces.
04 Outcomes
Qualitative
- Accurate indoor positioning via BLE beacon triangulation
- Custom indoor map overlays with turn-by-turn navigation
- Battery-efficient continuous Bluetooth scanning
- Environment-calibrated signal processing for accuracy
06 Constraints
- Must work accurately where GPS is unavailable
- BLE beacon signal calibration per environment
- Battery efficiency for continuous Bluetooth scanning
- Indoor map rendering with custom overlays
07 Innovation
BLE beacon triangulation for indoor positioning where GPS is unavailable. Custom signal processing algorithms for beacon ranging with environmental calibration to handle signal reflections and interference in indoor spaces.
