RTK Real-Time Kinematic GNSS GPS Module for Automotive Truck Car Vehicle Motorbike Scooter Locating & Tracking

Parameters of YW-16124G3 GPS Module

Detailed Explanation of Common Frequency Combinations and Applications for GPS/GNSS Modules:

1. Single-Band

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).

2. Dual-Band

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).

3. Key Selection Factors

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.
