Ocean monitoring with space equipment from
Saab Ericsson Space
JASON-1 is an earth observation satellite that will give us more data on
the world's oceans. It will be launched 7 December 2001 using a Boeing
Delta II rocket from a launch pad in California. The central data
handling system of the satellite has been supplied by Saab Ericsson
For a period of three to five years, JASON-1 will furnish information on
the topography of the world's oceans with aid of a radar altimeter. The
satellite is also equipped with other instruments for gathering data on
changes in sea levels, changes in seasonal ocean currents and their
effects on climate. Greater knowledge of the global interaction of
oceans and climate will contribute to, e.g., more reliable weather
forecasting. JASON-1 is a successor to Topex/Poseidon, the satellite
that predicted the El Niño phenomenon in 1997-1998.
Saab Ericsson Space has developed and manufactured the central
electronics unit of the satellite platform, the largest system of its
kind made by the company to date. It's an all-in-one system, i.e. its
units are integrated into a single system to carry out three different
main tasks. The system monitors and controls satellite and payload
functions, controls satellite attitude and includes a mass memory for
payload and housekeeping data. The company has also supplied the
satellite's S-band antennas for communication with facilities on the
Austrian Aerospace, a subsidiary of Saab Ericsson Space, has supplied
electronics that control the pyrotechnical devices of the satellite used
for releasing onboard mechanisms.
Jason-1 is built on a standardized satellite platform, called Proteus,
developed by French-based Alcatel. It is the first of a series of
satellites for earth observation and science.
JASON-1 will be put into a circular orbit at a bit more than 1300 km
altitude and will work together with other satellites to enhance data
gathering. The satellite measures 1 x 1 x 2 meters and weighs 500 kg.
Jason-1 is a joint project of NASA and the French space agency CNES.
