• Results (Observations of GS5 at station no.1)
• Deviation of GPS observed coordinates: eastings, northings and height above ellipsoid (H) from their mean values, at station no.1 for observations taken on different dates.
• Standard deviation of GPS observed coordinates: eastings, northings and height above ellipsoid (H) at different stations.
• Distances measured by GPS and total station, between IITK stations.
• Standard error of observations and computed distances
• Standard error of mean values of observations and computed distances
• Mean values of coordinates observed by single and dual frequency GPS receivers at station no.8.
• Error at test GCPs in terms of image pixels of corrected images (with RMS error of 0.727 using 5 GCPs)
• Conclusions
• Thank you
