Abstract
The Global Navigation Satellite System
Reflectometry (GNSS-R) concept was conceived as a
means to densify radar altimeter measurements of the sea
surface. Until now, the GNSS-R concept relied on open
access to GNSS transmitted codes. Recently, it has been
proposed that the ranging capability of the technique for
ocean altimetric applications can be improved by using all
the signals transmitted in the bandwidth allocated to GNSS,
which includes open access as well as encrypted signals.
The main objective of this study is to provide experimental
proof of this enhancement through a 2-day experiment on
the Zeeland Bridge (The Netherlands). In the experiment,
we used a custom built GNSS-R system, composed of high
gain GPS antennas, calibration subsystem, and an FPGAbased
signal processor which implemented the new
concepts, an X-band radar altimeter and a local geodetic
network. The results obtained indicate that the new
approach produces a significant improvement in GNSS-R
altimetric performance.
