We study the angular clustering of point sources in The GMRT Sky Survey (TGSS). The survey at $150$~MHz with $\delta > -53.5^\circ$ has a sky coverage of $3.6\pi$~steradian, i.e., $90\%$ of the whole sky. We define our sample and study angular clustering of point sources at large scales for different subsamples. We find that there is a break in angular clustering at a scale of about one degree. We compare our results with other studies of clustering of point sources. We use the available data to present the variation of clustering with the flux limit at $150$~MHz. We also present results of cross-matching sources with the SDSS redshift surveys and estimation of the two point correlation function.
