Multi-Band GNSS Antennas Explained | L1 vs L2 vs L5 Bands by Eteily Technologies

By

Introduction

Global Navigation Satellite System (GNSS) technology has progressed much beyond basic positioning. Modern applications such as autonomous cars, precision agriculture, surveying, UAVs, and time synchronization need greater accuracy, quicker convergence, and interference resistance.

Multi-band GNSS antennas, which handle the L1, L2, and L5 frequency bands, are crucial in this situation. These antennas increase position accuracy, dependability, and robustness by receiving signals from many bands.

In this article, we will discuss GNSS frequency bands, how L1, L2, and L5 vary, and why multi-band GNSS antennas are required for current positioning systems.

What is GNSS?

The name "GNSS" (Global Navigation Satellite System) refers to all satellite-based positioning systems, which include:

  • GPS (USA)
  • GLONASS (Russia).
  • Galileo (EU
  • Beidou (China)
  • QRZSS (Japan)
  • IRNSS/NavIC (India)

GNSS antennas are intended to pick up signals from these constellations over one or more frequency bands.

Understanding the GNSS Frequency Bands

GNSS signals are sent in the L band (1-2 GHz). Each band has distinct properties in terms of accuracy, penetration, and interference resistance.

Primary GNSS Bands
