Supported Bands (typically one is selected):
L1 Band
Frequency: 1575.42 MHz
Systems: Supported by GPS (USA), GLONASS (Russia), Galileo (EU), and BeiDou (China).
Features: Basic positioning, low cost, low power consumption, suitable for consumer devices (e.g., car navigation, smartphones).
L2 Band
Frequency: 1227.60 MHz
Systems: GPS L2C, GLONASS G2.
Features: Used in military and some high-precision civilian applications; better multipath resistance than L1.
L5 Band
Frequency: 1176.45 MHz
Systems: GPS L5, Galileo E5a, BeiDou B2a.
Features: Designed for aviation and life-critical applications; stronger signal, suitable for dynamic environments (e.g., drones, emergency rescue).
Common Combinations (supports two bands simultaneously):
L1 + L5
Advantages:
L1 for basic positioning, L5 for improved accuracy (1–3 meters) and anti-interference.
Ideal for high-dynamic scenarios like car navigation and shared bikes.
L1 + L2
Advantages:
L2 helps eliminate ionospheric errors, achieving sub-meter accuracy.
Commonly used in surveying and agricultural machinery (e.g., RTK base stations).
L1 + B1 (BeiDou)
Frequency: B1 = 1561.098 MHz
Advantages: Optimized for BeiDou compatibility, enhancing positioning in the Asia-Pacific region.
Multi-System Dual-Band (e.g., GPS L1 + Galileo E5)
Advantages: Increases satellite availability, improving reliability in challenging environments (e.g., urban canyons).
Accuracy Requirements:
Single-band (L1): 5–10 meters error (consumer-grade).
Dual-band (L1/L5): 1–3 meters error (high-precision applications).
Cost & Power Consumption:
Single-band modules are cheaper and more power-efficient.
Dual-band modules cost 30%–50% more with higher power usage.
Regional Support:
Europe: Prefer Galileo E1/E5.
China: Prefer BeiDou B1/B2.
| Band Type | Application Scenarios | Example Devices |
| Single-band (L1) | Car navigation, smartphones | Basic dash cams, shared bike locks |
| Dual-band (L1/L5) | Drones, ADAS (advanced driving) | drones, Tesla Autopilot |
| Dual-band (L1/L2) | Surveying, precision agriculture | RTK terminals, tractors |
