AltiTrek — Offline Trail Navigation & 3D Spatial Telemetry
Engineered for mountaineering, endurance trail running, and cycling in remote backcountry environments without cellular infrastructure. AltiTrek fuses multi-constellation GNSS satellite positioning with on-device MEMS barometric pressure sensing for millibar-accurate elevation, vertical climb velocity, and autonomous squall forecasting. Connects to Bluetooth Low Energy (BLE) cardiac monitors, guides offline navigation with turn-by-turn routing, and reconstructs recorded sessions across interactive 3D spatial terrain models.
Reconstruct Expedition Routes in 3D Spatial Coordinate Space
Conduct granular post-session spatial analysis. Evaluate localized gradient variations, isolate critical climb crux milestones, and correlate velocity with biometric cardiac output across full 3D terrain models.
3D Vector & Satellite Topographic Terrain
Extrudes GPS tracks into 3D spatial coordinate space with vertical elevation pillars color-coded by slope gradient steepness (>8%, 3–8%, flat, descent). Manipulate 3D camera orbit, pitch, and altitude to examine true topographic contours.
Automated Crux & Peak Exertion Detection
Telemetry algorithms automatically isolate the route's most demanding ascent grade (Crux), peak velocity, and summit milestone. Scrub along the timeline to inspect microsecond-synced speed, heart rate, elevation, and instantaneous slope angle.
Granular Telemetry Scrubbing
Inspect any coordinate along the route with precision scrubbing to review instantaneous velocity, heart rate (BPM), barometric elevation, and slope incline angle.
Autonomous Route Following & Staging
Ingest saved expeditions or third-party GPX tracks directly into the navigation engine for offline turn-by-turn guidance and voice split updates.
Adaptive Geospatial Viewport
Instantly toggle between a panoramic full-screen vector map and a synchronized multi-metric telemetry diagnostic dashboard.
