Data Collection System
Outlines and Activities.
|Communication range of Himawari-DCS|
The Data Collection System (DCS) is used to collect and relay data via earth-based observation channels
(Data Collection Platforms, or DCPs) within the communication range of a geostationary satellite such as Himawari-8.
A DCP is an electronic configuration used to collect data from observation and monitoring of oceanic, solid earth and atmospheric parameters such as temperature, pressure and tide levels. DCPs within Himawari-8’s communication range encode and transmit their observation data to the satellite, which in turn relays the information to ground stations operated by HOPE. DCP data are then transmitted by HOPE to JMA, which processes the information and provides related products to users. Finally, the data are transmitted back to DCP operators and users via the Global Telecommunication System (GTS).
In addition to the DCP support function, the Himawari-8 DCS supports exchanges of earthquake-related information. The satellite collects seismic intensity data from earthquake observation sites all over Japan. Its DCS also supports dissemination of emergency tsunami/earthquake information within the Himawari-8 communication range.
The two DCS systems are the International DCS (IDCS) and the Regional DCS (RDCS). IDCS is designed to support DCPs hosted on ships that sail beyond the communication range of Himawari-8 and into those of other geostationary meteorological satellites. RDCS is designed to support fixed DCPs such as automated remote weather stations and tide/tsunami gauges, and also DCPs on ships that remain within the communication range of Himawari-8.
