Data Collection System (DCS)
The GOES is an integrated system of Earth and space environmental
sensors which provide nearly continuous observational information
to ground-based user stations. This system consists of several observing
subsystems including the data collection system (DCS). The DCS uses
the GOES spacecraft for the relay of data from remotely located in-situ
at or near the Earth's surface with areal coverage extending westward
from western Europe and Africa through the Americas to eastern Australia.
The DCS supports a certain number of reply channels that are common
to the other geostationary meteorological satellites operated by Russia,
China, Japan, and the European Space Agency which enables mobile platforms
to use the data collection system.
The GOES DCS is a communications relay system that uses the transponder
carried on the GOES to relay UHF transmissions from data collection
platforms (DCP's) by S-band (1694.5 MHZ) to properly equipped ground
receive stations.
The DCS has the capacity of handling at least 25,320 messages from
DCP sites via the spacecraft transponder in each one hour period.
The four Functional Subsystems are (see Figure):
- Deployed Data Collection Platforms
- East and West Spacecraft
- Command and Data Acquisition Station
- DOMSAT Data Dissemination Spacecraft
