DGPS Stations
 

Each DGPS Broadcast Station provides DGPS corrections to users in its region via marine radio beacon signals. Marine radio beacons, which operate in the 283.5 to 325.0 KHz frequency band, broadcast DGPS corrections by modulating the normal beacon direction-finding signal with the DGPS correction information. The signals are received by the beacon receiver on board the user’s vessel and are demodulated to recover the DGPS corrections.

The DGPS corrections are transmitted from 23 locations spread across India

Following are the details of 23 DGPS installations along the Indian coast including Andman Nikobar & Lakshadweep group of islands.
