Here's how ISRO will be tracking the PSLV-C25

It will take off from the Sriharikota space station tomorrow at 14.38 hours

A complex network of ground stations, as indicated in the image, has been laid out for keeping an eye on the various phases of PSLV-C25/ Isro's Mars Orbiter Mission (MOM), including the launch, Earth bound maneuvers, Heliocentric phase as well as the Martian phase.

Additionally, two ship borne terminals have also been deployed in the southern Pacific Ocean to cover critical events during the launch phase.

After satellite separation from the launch vehicle, the Spacecraft operations are controlled from the Spacecraft Control Centre of ISRO Telemetry, Tracking And Command Network  (ISTRAC) in Bangalore.
