Key Features and Benefits of Youwei GNSS Modules

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

72-channel GPS 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: <15 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.

Application Scenarios of Youwei GPS tracking modules

Industry Use Case Module Advantage
Automotive Fleet tracking, stolen vehicle recovery High update rate (10Hz) for real-time motion tracking
Aviation UAV navigation, waypoint following Centimeter-level precision with RTK support (optional)
Wearables Elderly/child safety trackers Low power extends battery life to 7+ days
Logistics Container/asset monitoring Anti-jamming design ensures reliability in metal-rich environments
Smart Agriculture Autonomous tractor guidance Dual-frequency (L1/L2) support for sub-meter accuracy
