Direct Broadcast Network Latest News

Recently, the National Centre for Medium Range Weather Forecasting (NCMRWF) signed a Memorandum of Understanding (MoU) with New Space India Limited (NSIL) to establish two Direct Broadcast Network (DBNet) stations in Delhi/NCR and Chennai. 

About Direct Broadcast Network

• The DBNet is a global operational framework designed for the real-time acquisition of satellite data from Low Earth Orbit (LEO) satellites.
• It plays a critical role in Numerical Weather Prediction (NWP) and supports a wide range of applications, including weather forecasting, cyclone monitoring, and climate research.
• DBNet stations ensure rapid data availability, hence significantly improving the accuracy and timeliness of weather forecasts and related services.
• The proposed DBNet stations will be capable of receiving direct broadcast data from various existing Indian and international Earth Observing System (EOS) satellites, including Oceansat, NOAA, and MetOp.
• Key Benefits:

• • Timeliness for NWP: It provides the near real-time availability of LEO satellite data, which is essential for generating high-resolution, short- to medium-range weather forecasts.
  • Reduced Data Latency: DBNet captures data directly as satellites pass overhead, overcoming latency issues and enabling faster data delivery.
  • Rapid Processing: NCMRWF will complete the full data processing chain within 5 minutes of a satellite overpass, ensuring timely ingestion of these datasets into MoES’s NWP models for across-scale forecasting.
