  We present measurements on Earth's gravitational acceleration (g) using an
in-house developed cold atom gravimeter (CAG) in an atomic fountain geometry.
In the setup, the laser cooled $^{87}Rb$ atoms are launched vertically up in
the fountain geometry and Doppler sensitive two-photon Raman pulse atom
interferometry is applied to detect the gravitational acceleration experienced
by the atoms. Using our gravimeter setup, we have measured the local value of
'g' in our laboratory with sensitivity of 621 $\mu$Gal for integration time of
1350 s.
