. Per capita arable land is decreasing due to the rapidlyincreasing population, and fresh water is becoming scarce and moreexpensive. Therefore, farmers should continue to use technology andinnovative solutions to improve efficiency, save input costs, and optimiseenvironmental resources (such as water). In the case study presented in thispaper, the Global Navigation Satellite Systeminterferometric reflectometry (GNSS-IR) technique was used to monitor soil moisture during66 d, from 3 December 2018 to 6 February 2019, in the installations ofthe Cajamar Centre of Experiences, Paiporta, Valencia, Spain. Two mainobjectives were pursued. The first was the extension of the technique to amulti-constellation solution using GPS, GLONASS, and GALILEO satellites, andthe second was to test whether mass-market sensors could be used for thistechnique. Both objectives were achieved. At the same time that the GNSSobservations were made, soil samples taken at 5 cm depth were used for soilmoisture determination to establish a reference data set. Based on acomparison with that reference data set, all GNSS solutions, including thethree constellations and the two sensors (geodetic and mass market), werehighly correlated, with a correlation coefficient between 0.7 and 0.85.
