LAPAN-A2 FM and APRS Satellite Launched


The Indonesian amateur radiosociety ORARI report that on Monday, September
28, 2015 04:30 hours UT, theLAPAN-A2/ORARI satellite was launched from the
Sriharikota Range (SHAR) ofthe Satish Dhawan Space Centre in India.
Deployment
took place  23 minuteslater.

LAPAN-A2 is in a 650 km orbit with an inclination of 6 degrees. Ittakes
about
110 minutes to orbit the Earth and should pass over Indonesiaand other near
equatorial locations 14 times a day.

The lowinclination equatorial orbit means it will be receivable from
about30
degrees North to 30 degrees South. About a third of the world’spopulation,
over 2.4 billion people, live within the coverage area of thesatellite.

The ground station at the LAPAN Satellite Technology Centre inRancabungur,
Bogor has made contact with LAPAN-A2. There will now be a periodof
activation
and testing of all the satellite systems and it is expectedto be about
a month
before the amateur radio payload becomes available forgeneral use.

The primary aims of the mission are Earth observation usingan RGB
camera and
maritime traffic monitoring using AIS, both usingfrequencies outside the
Amateur Satellite Service.

The IARU hascoordinated these frequencies for LAPA-A2/ORARI:
• 437.425 MHz telemetrybeacon
• 435.880 MHz FM uplink
• 145.880 MHz FM downlink (5 watts)
•145.825 APRS digipeater (5 watts)

Please send reports to
