Executive summary
Satellite navigation relies on receiving signals from
satellites through GNSS/GPS signals broadcast in
the L-band, typically within the 1-2 GHz frequency
range. The L-band comprises two main sections:
the lower band (from 1164 MHz to 1300 MHz) and
the upper band (from 1559 MHz to 1610 MHz).
Most satellite constellations transmit their data
using these two band sections.
Since satellite navigation technology became
available for public use, the upper L-band, also
known as the L1 band, has been the band most
devices rely on. However, this landscape is evolving
at a rapid pace. Signicant advancements in
GNSS receiver technology are making multi-band
receivers increasingly attractive and viable options
for a growing number of applications.
While one might think multiple bands are a better
choice for device requirements, this is not always
true. In fact, the choice between a single-band or a
dual-band GNSS receiver depends on the specic
purpose of the positioning application.
This white paper aims to provide a comprehensive
guide to positioning technology. To achieve this,
it compares the dierences between single-band
and dual-band GNSS receivers and oers a detailed
analysis of the best band combinations for specic
use cases. As a result, readers will gain a thorough
understanding, enabling them to make informed
decisions about what bands favor their GNSS
applications.
