Abstract

This paper aims to investigate the relationship between the multipath phase of
Global Navigation Satellite System (GNSS) and volumetric moisture content
(VMC) of soil. The carrier to noise ratio (C/No) data of multipath signals at
two different frequencies has been analyzed. The first one is India’s NavIC
L5 frequency (∼1176 MHz) and the second one is GPS L1 frequency (∼1575
MHz). The received multipath signals are highly dependent on dielectric
value of soil and the elevation angle of satellite. The relationship drawn for
the NavIC and GPS C/No data is based on multipath phase analysis and
in situ soil moisture. The values of correlation coefficient observed between
these parameters were 0.9 and 0.63 for NavIC and GPS multipath signal
respectively. The result from both GNSS shows good sensitivity and could
be used to estimate the soil moisture for agricultural land
