1, Enhanced Weak-Signal Performance
Advanced signal processing algorithms enable reliable satellite acquisition and tracking even in challenging environments (e.g., urban canyons, dense foliage).
2, Multi-Channel, Multi-Constellation Support
Multi-channel receiver architecture ensures simultaneous tracking of GPS, GLONASS, Galileo, and BeiDou satellites, delivering <2.5m positioning accuracy and faster Time-to-First-Fix (TTFF).
3, Optimized Startup Modes
Hot start: <1 sec (retains ephemeris data)
Warm start: <28 sec (uses almanac data)
Cold start: <30 sec (full satellite search)
4, High-Precision 3D Positioning
Provides horizontal (latitude/longitude) and vertical (altitude) coordinates with minimal drift, suitable for altitude-sensitive applications like drones.
5, Ultra-Low Power Design
Adaptive power management reduces consumption to <25mA in continuous mode, ideal for battery-operated IoT devices.
6, Robust Environmental Resilience
Operates in -40°C to +85°C temperatures and resists interference from industrial EMI/RFI sources.
7, Multipath Mitigation Technology
Proprietary algorithms suppress reflected signal errors, improving accuracy in urban areas by up to 40%.
8, Global Compatibility
Seamless integration with all major GNSS constellations for worldwide coverage.
