NAADI: National Analytical Platform for Dealing with Intelligent Tracing, Tracking and Containment of COVID19 Pandemic

Naadi LogoUnder the SAMHAR-COVID19 Program of C-DAC, we have developed a platform called NAADI: National Analytical Platform for Dealing with Intelligent Tracing, Tracking and Containment of COVID-19 for infected persons and quarantined people. NAADI offers along with Two Mobile applications namely, 112++ India App for Citizens and nCov Satark App for Health Professionals and Government Decision makers.

This platform has extensively used the expertise garnered by three successful platforms developed by C-DAC; Emergency Response Support System (ERSS),e-Sanjeevni & Mercury: Tele-medicine Solution and "Suraksha Mitr" Vehicle Tracking System (VTS). ERSS is an integrated system that provides a common platform to receive distress calls in the form of voice, message, email, panic signal etc. through a Single Number '112'. C-DAC has carried out Nation-wide deployment of '112 system' and around 5.5 Lakh downloads of '112 India App' by users have facilitated saving many lives and persons in distress. e-Sanjeevni and Mercury are already deployed in Ten States. VTS is also a well proven system for online tracing and tracking of vehicles.
