Roket Pengorbit Satelit (RPS-01)
Indonesian National Institute of Aeronautics and Space (LAPAN)
Space and Aeronautics Institute (LAPAN) plans to launch its RX-420 rocket for the
first time on July 2. RX-420 rocket fabrication took three months only, with specification
as follows: 420 mm diameter, 1,000 kg launching load, 6,200 mm long, fuel solid,
13 sec combustion time, 205 sec departure time, 4.5 mach maximum speed, 101 km predicted
cruise distance range, 53 km predicted vertical distance and with load: diagnostic
tool, GPS, altitude-meter, gyro, 3-axis accelerometer, processor and battery.
The RX-420 rocket is the forerunner to Indonesia's next indigenous orbital satellite launching vehicle program. The announcement was made by Research and Technology Minister Kusmayanto Kadiman in Jakarta. During a meeting with Commission VII of the House of Representatives, Kadiman said the launch of the RX-420 rocket, with a range of 100 km, will be conducted by LAPAN, which had successfully launched a RX-320 rocket in 2008. He added that the RX-420 rocket possessed more power than the RX-320 and its range could be increased to 190 km if the rocket's weight was reduced. Apart from the scheduled launch in July, there are plans to carry out further test launches in 2010 and 2011. In 2014, LAPAN will have finished all its experimental rocket launches and will have already developed a rocket with a range of 300 km and speed of 7.8 km/sec allowing it to carry a small satellite into space, he said, adding that this would be a “monumental achievement.”
LAPAN or Lembaga Antariksa dan Penerbangan Nasional (National Institute of Aeronautics and Space) is the government space agency. It was established on November 27, 1964 by President Suharto.
that already 45 years on November 27, since 2007 had boosted rocket and satellite
study and development, especially after got ability to produce solid rocket fuel.
In 2007, RX-250 (250 mm) had been launched successfully with distance 53 km. After good result on static test, RX-320 rocket has successfully launched in Pameungpek, West Java on May 19, 2008 by transmitting navigation system data, aerodynamics performance, trajectory, environment condition and any obstruction during launching. The special improvement from this test was RX-320 rocket used Indonesian own solid propellant. RX-320 rocket has dimension 320 mm diameter x 4,736 mm long and weight 532 kg. The trust power is 52 ton and reached 42 km as per design.
After successfully launched that experimental rocket with diameter 320 mm or coded RX-320, LAPAN again succeeded static test RX-420 on 23/12/2008 at LAPAN Aerospace Technology Center, Tarogong, Tangerang. In 2009, Chief of LAPAN Adi Sadewo Salatun said after successful static test of RX-420, rocket launching program will be continued in 2009.
This RX-420 rocket is the main part of the first LAPAN satellite orbital launching vehicle (RPS) that scheduled in 2014, said by Yus Kadarusman Markis, chief of LAPAN Aerospace Technology Center. The RPS consists of three-stage rockets, which is in the first stage will be three RX-420 as booster, in second stage one RX-420 as sustainer and the last is RX-320. With that configuration and LAPAN solid fuel, the SLV-1 has capability to launch nano satellite to the orbit.
One RX-420 rocket is designed to have distance range about 120 km. With RPS configuration, it may reach a vertical height up to 400 km. This rocket can be loaded 5 kg load to be able to the orbit minimum 250 km high and at horizontal speed at 8 km/sec.
For the next development, LAPAN will develop rockets with bigger diameter, such as RX-750, and liquid fuel that has better performance than solid fuel. RX-420 is the sixth rocket developed by Lapan after 70, 100, 150, 250, and 320 mm.

pad at Lapan Space Center.

LAPAN rockets are classified "RX" (Roket Eksperimental) followed by the diameter in millimeters. LAPAN's current workhouse rocket propulsion system consists of four stages, namely the three-stage RX 420 and the RX-320 level. It is planned to use the RX-420 as a booster (rocket booster) RPS for the planned Roket Pengorbit Satelit ("Orbital Satellite Rocket") planned to fly in 2014.
