Network Adjustment Strategy
Coordinates of CORS will be computed with reference to ITRF 2008 (Epoch2005) coordinates of
IGS Stations. Here epoch referes to the co-ordinates
ordinates of IGS station on 1 st January, 2005. We are
adjusting the co-ordinatesordinates of 1 st
phase points with reference to Permanent Continuous
Operating Reference Stations (CORS). As we know that the Indian plate is moving like other
plates of earth due to plate tectonic. It is also seen that Indian plate is having appreciable
velocity of the order of 5-6 cm par annum.
If we adjust our Ist Phase points with respect to our permanent CORS better adjustment will
result under appreciable velocity of Indian plate.
