ISRO, Oppo collaborate to strengthen R&D of NavIC messaging service
The NavIC system provides regional navigation services covering the Indian mainland and an area up to 1,500 km beyond the Indian mainland. In addition to its primary function of providing PNT (position, navigation and timing) services, NavIC is also capable of broadcasting short messages.
The messaging service is mainly used for broadcasting safety-of-life alerts in areas with poor or no communication, particularly in the oceans. Pic: https://www.isro.gov.in/
