Description

The Seeed Studio Studio L76K is a versatile Multi-GNSS module designed for seamless integration with all Seeed Studio Studio XIAO development boards. It supports multiple global navigation satellite systems, including GPS, BeiDou (BDS), GLONASS, and QZSS, allowing for flexible multi-system combined or single-system independent positioning configurations. This robust capability is essential for applications requiring precise location data across various geographical regions.

Equipped with an advanced active GNSS antenna, a built-in low-noise amplifier, and a sound surface filter, the L76K delivers exceptional positioning performance characterized by fast acquisition times, high accuracy, and overall reliability. Its AGNSS function further accelerates cold and hot starts, significantly reducing the time-to-first-fix. The module’s design incorporates a tiny bright green LED to indicate 1PPS output upon achieving a satellite fix, providing clear operational status feedback for developers and users.

This module provides a robust foundation for precision navigation in UAVs, robotics, IoT devices, and smart city infrastructure. Its compact form factor and comprehensive GNSS support make it an ideal choice for projects where space is limited but high-fidelity positional data is critical.

Key Features

  • Supports GPS, BeiDou B1, GLONASS L1, and QZSS for broad global satellite coverage.
  • Integrated Low Noise Amplifier (LNA) and Surface Acoustic Wave (SAW) filter enhance signal sensitivity and mitigate interference.
  • High precision positioning with 32 tracking and 72 acquisition channels, offering 2.0m CEP accuracy.
  • Exceptional tracking sensitivity of -162dBm and re-acquisition sensitivity of -160dBm ensures reliable fixes in challenging environments.
  • Fast time-to-first-fix with AGNSS, achieving cold starts in 5.5s and hot starts in 2s.
  • Low power consumption: 41mA during tracking and acquisition, and a mere 360µA in standby mode.
  • Compact design with an active GNSS antenna featuring an RF1.13 coaxial cable and U.FL connector for easy integration.

Applications

  • High-precision GPS navigation for autonomous UAVs and robotic platforms.
  • GPS tracking solutions for asset management, fleet monitoring, and industrial logistics.
  • Integration into Smart City infrastructure for environmental sensing and location-aware services.
  • Logistics and freight management systems requiring accurate real-time positional data.
  • Compact IoT devices and embedded systems requiring reliable location services.

Frequently Asked Questions

What GNSS systems does the Seeed Studio Studio L76K module support?

The L76K module provides comprehensive multi-GNSS support, integrating GPS, BeiDou (BDS), GLONASS, and QZSS satellite systems. This ensures broad global coverage and enhances positioning accuracy and reliability by utilizing multiple constellations simultaneously. It can operate in combined or single-system independent modes.

What are the key benefits of the L76K's integrated antenna and filtering?

The module features an integrated active GNSS antenna, a low-noise amplifier (LNA), and a surface acoustic wave (SAW) filter. This combination significantly boosts signal reception sensitivity, minimizes external noise interference, and ensures robust performance even in challenging environments. It improves overall positioning stability and speed.

How quickly can the L76K module acquire a satellite fix?

With its AGNSS (Assisted GNSS) functionality, the L76K achieves rapid satellite acquisition. Cold starts can be as fast as 5.5 seconds, while hot starts take merely 2 seconds. This quick time-to-first-fix is critical for applications demanding immediate and consistent positional data, such as drone takeoffs.

What protocols and interfaces does the L76K use for data communication?

The L76K module primarily communicates using the standard NMEA 0183 protocol, commonly used in marine and aviation electronics for GPS data. It also supports CASIC proprietary protocols. Data transmission occurs via a serial UART interface, configurable with baud rates ranging from 9600 to 115200bps, with 9600bps as default.

Package Includes

  • 1x Seeed Studio Studio L76K GNSS Module
  • 1x Active GNSS Antenna with U.FL (iPEX) Connector
  • 2x 7 Pin Female Headers (2.54mm pitch)
