GPS Receiver

Integrated Water Vapour Measurement using Dual Frequency GPS Receiver

GPS (Global Positioning System) receiver receives signals at two frequencies 1575.42 MHz (L1) and 1227.60 MHz (L2) transmitted from satellite. Ground based GPS receiver converts satellite transmitted signals into position, velocity and time co-ordinate

Minimum of four satellites are required to compute the position and time. GPS receivers are used to study Integrated Water Vapour by estimating Zenith Tropospheric Delay. It can also be used to study Total Electron Content by using Ionospheric delay.
