National Aeronautics and Space
Institute (LAPAN) has completed the manufacture of satellite Lapan A2. The
plan this satellite will be launched into orbit next year, using the Indian
rocket from Sriharikota.
This satellite is the successor
of the previous success of Space agency satellite, Satellite A1 Tubsat. After
orbiting, Lapan A2 will be used for earth observation missions, vessel
monitoring, and amateur radio communications.
In addition to having the
ability to monitor the Earth's surface through video survailence as in A1
satellite Tubsat, in the A2 version added more sensors, the advanced receiver
Automatic Identification System (AIS), an amateur radio payload through
Posisition Automatic Reporting System (APRS) and analog video cameras and better digital.
Sensor Automatic Identification
System (AIS) is used to detect ships passing through the waters of Indonesia. This
technology is even able to detect potential illegal fishing in Indonesian
waters. "Each
ship is equipped with a transmitter legally, so tracked its position,"
said Heru Robertus Triharjanto, Head of Bus Technology Satellite, Satellite
Center Space agency, Rancabungur, Bogor, yesterday.
While sensor Posisition
Automatic Reporting System (APRS) functions provide communication facilities
for disaster mitigation assistance through text and voice communications via
amateur radio. "For
example, disaster, and death communication, the data from these satellites
provide an alternative communication aid through amateur radio," he added.
Valued at USD 35 billion
satellite will orbit at an altitude of 650 km with a pattern along the
equatorial region of Indonesia that as many as 14 times, more often if the
satellite orbit polarial. "So
it would be optimal to monitor the waters of Indonesia, we also do optimization
for more precise control of the satellite," said Head of Satellite Space
agency, Suhermanto, on the same occasion.
Pioneers Mandiri
Satellite Lapan A2 is the
overall satellite design and operations are conducted in the country. "From
the testing, design, operation, all done in the country," said Suhermanto.
This ability is obtained while
developing the Satellite Space agency A1-Tubsat, conducted in Berlin, Germany,
in 2007. Since
the development of A1-Tubsat, Space agency did look serious in satellite
development.
Development was then carried
out at the Centre for Satellite Technology Space agency, Rancabungur, Bogor,
West Java. Not
easy to reach this place, because it should be down the narrow streets to get
to this place. But
from being in the remote location Space agency is preparing satellite to be
launched.
Since passing through the gate,
the seriousness Space agency already visible in the satellite building. A
number of buildings visible equipped with disc (dish) like a big satellite
dish. This
is one of the facilities on ground earth stations or centers. Space
agency itself has five stations, namely in Bogor, Serpong, Biak, Kotatabang,
and Pontianak.
According Suhermanto, to
support domestic security, satellite development is a serious matter. Space
agency because it did not stop at making Lapan A2, but also square off to
launch two other satellites, the A3 and A4.
Currently, Lapan A2 still uses
components from abroad. But
the A3 is targeted for launch in 2014, will use a Space agency targeting
supporters who cultivated in the country. "After
the transfer of technology, the existing systems in satellites should be in our
hands," he said.
Proficiency level of these
systems is the reaction wheel, star sensor (a navigational satellite attitude
can move the camera), camera, PCDH (Payload Handling Control Data),
transmitter, coding and encoding the data transmission.
Head of Technology Satellite
Bus, Robert Haru Triharjanto, said satellite A3 will come with loads of earth
observation camera with 4 band multispectral scanning camera. This
satellite is used to map the land cover classification and environmental
monitoring.
The camera resolution of 18 m
with a coverage of 120 km and a camera resolution of 6 m with a coverage of 12
km x 12 km. This
satellite will also orbit 650 km. "So,
can identify the type and age of the plant were censored," he said
If successful launches A3
Satellites, Space agency to immediately resume the construction of a dedicated
satellite for operational satellites in 2017 to bring the A4.
This satellite is called will
be applied specifically to forestry and fisheries. Specifically
for the development of operational satellites, Space agency will hold parties
signaled abroad. "We're
working together to explore Hokkaido University, Japan," said Suhermanto.
