The Metro system will soon get state-of-the-art technological support for its construction.
Nine satellites orbiting the earth will be put in use for mapping the alignment of the second Metro line to be constructed, which is the 32-km Charkop-Bandra-Mankhurd line.
These satellites will coordinate and map the entire stretch and will undertake the topography survey of the area through which the Metro will run.
The Mumbai Metropolitan Region Development Authority (MMRDA) hopes to finish construction of this line by 2015.
The first Metro line to be constructed will be the 11.07 km Versova-Andheri-Ghatkopar line, which the MMRDA says will be constructed by the end of this year.
The MMRDA has given consent to Reliance Infra, which is building the second line, to rope in Fugro, a Netherland-based company, to implement Differential Global Positioning System (DGPS).
The Global Positioning System (GPS) is a space-based global navigation satellite system that provides reliable location information.
This system will coordinate and map the entire 32-km stretch using the help of 9 satellites. It is for the first time that such a highly accurate technology is being used in the Metro rail construction across the country.
This system is expected to expedite construction of Line II of the proposed Metro corridor, because the DGPS will undertake the topography survey and help in mapping of the alignment along the corridor.
“This technology will be extremely beneficial as it is expected to speed up the construction of Line II of the Metro in very quick time,” Metropolitan Commissioner Ratnakar Gaikwad said.
The DGPS will ensure the probability of the error is minimal, because it will have exceptional accuracy and ensure smooth completion of the project.
