Automatic Packet Reporting System ( APRS) is an amateur radio -based system for real time digital communications of information of immediate value in the local area. [1] Data can include object Global Positioning System (GPS) coordinates Non-directional beacon, weather station telemetry, text messages, announcements, queries, and other telemetry.
The automatic identification system ( AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS). When satellites are used to receive AIS signatures, the term Satellite-AIS (S-AIS) is used. AIS information supplements marine radar, which continues to be the primary method of collision ...
The Indian Regional Navigation Satellite System ( IRNSS ), with an operational name of NavIC (acronym for Navigation with Indian Constellation; also, nāvik 'sailor' or 'navigator' in Indian languages), [2] is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services. [3]
