According to Law 21 In 2013 about Keantariksaan Law, Space agency is required to prepare a master plan to guide the implementation nasionaluntuk keantariksaan. One of the keantariksaan activity is mastery of satellite technology for telecommunications applications, remote sensing, navigation and science. In this case sayelit Technology Center as a unit which is obliged to draw up a national satellite technology development program held a focus group discussion (FGD) on 13-14 May 2014 ago.The purpose of the forum is for socializing satellite development program in Space agency and other institutions in Indonesia with the aim to ensure the coordination with these institutions. The event was attended by representatives of government agencies; Space agency including, BPPT, BIG, Ministry of Research and Technology, Ministry of Defense, Ministry of Communication and Information, the Ministry of Industry; industry representatives, including PT.DI, PT.INTI, as well as the association of the satellite communications services provider, ASSI; and representatives of academia, diantarnta IT, IPB, PENS, Surya University, and the University of Telkom. In the forum, the participants explained the status of the program within their own satellites, and expressed ideas related to the development of satellite technology in Indonesia.

In addition to the above Act Keantariksaan socialization, Space agency also explained about the mastery program conducted experimental satellite technology Satellite Technology Center, as well as the discourse on national satellite technology master plan. Regarding control of satellite technology experimental satellite was delivered that development in the country has resulted in satelitkelas micro-A2 Space agency that has been ready to be launched late in 2012 Furthermore, middle-class satellite was developed micro-A3 Space agency that has considerable technological leap over previous satellite, which will begin to approach the operating requirements of satellite remote sensing. As for national satellite development petajalan Space agency that discourse is as in Figure 2, where the planned satellite pengembangkan greater good for telecommunications and remote sensing missions, involving a national consortium.

Most of the presentations delivered on the needs of satellite technology in Indonesia, both for application of telecommunications, remote sensing, navigation, and science. For remote sensing, the current that needs spatial data mapped from satellite imagery over Indonesia, for kepentinganpengelolaan natural resources and land use, which was purchased by various government agencies, such as the Ministry of Fisheries, Ministry of Agriculture, and BIG is about 5.5 million dollars per year. BIG, for example, has had a base map for the entire territory of Indonesia slaka above 1: 100000, but still need a base map with a scale smaller than 1: 50000, which should dipernuhi with satellite imagery. Furthermore, based on the user requirements study conducted BPPT and Space agency, required sensing face of the earth using satellite technology radar (SAR) to complete the optical remote sensing technology, which is currently used. The technology has the advantage of being able to produce images in any weather conditions. This study is in line with the satellite programs that discourse Space agency, where the micro-satellite to 5 (A5) will carry a payload of SAR. Also in line denganupaya Space agency and BPPT, led olehKementerian Research and Technology, Central satellite consortium to finalize the establishment of a national penginderaam far. Consortium tersebutbertujuan that Indonesia may have its own remote sensing satellites, to meet most of the needs of national (satellite series B on petajalan LAPAN).


For telecommunications applications, there are several telecommunication satellites managed by national companies such as Telkom, Indosat, MNC, and PSN, as well as in the near future will be added BRI. However, so the transponder is owned by the national company that can meet only about 30-40% of the national demand, dansisanya by 60-70% is still served by a foreign party. It can be concluded that Indonesia still needs additional satellite telecommunications satellite nasional.Konsep C series was initiated in petajalan Space agency is one alternative to absorb national needs, especially telecommunications spending by the government.


In addition to civil telecom applications, the Ministry of Defence has also made a study on the need for the use of telecommunications satellites for national defense purposes. Obtained from studies conducted by the mission requirements for telecommunications special security units to static (C / Ku-band) and moving (L-band), whose numbers continue to grow according to the demands of modernization and keamaman defense system. Currently the special telecommunication lines provided by a national company. Along with the government's discourse of telecommunications satellites (series C in petajalan Space agency), the Ministry of Defence will make a further study whether the defense commucation mission could be better served by satellite government.


For navigation applications, current applications of GNSS in Indonesia has expanded to keperluankeamanan transportation, both modes of air, sea, and land. In addition, GNSS is also used for geological surveys, emergency response operations, and that the operation of the equipment pertambangan.penyedia GNSS services is also increasing (US-owned GPS, the Russian Glonass and Compass belongs to China). But until now, there has been no national policy regarding settings. Other applications of GNSS is to study space weather. This has been done the Deputy Science Space agency with various receiving stations owned and BIG Space agency in Indonesia. Knowledge of the interference signal obtained by the atmosphere can be used to provide correction of GPS navigation. So there is the potential to be able to make the GPS accuracy in Indonesia for the better as it is done in America, Europe, and India.


For scientific applications, the current satellite technology center and science center space Space agency is developing magnetic sensors will be placed in a micro satellite LAPAN-A4. The sensor will read the small changes in the Earth's magnetic field, which can be reduced to reading on solar activity. In this forum also discussed the development opportunities of radio occultation measurements missions utilizing GNSS signals, in satellite LAPAN-A5. If it can happen, will be able to strengthen research in the Deputy Science Space agency.


Sustainable development of satellite technology will require the support of a good industrial infrastructure SDMdan. This is particularly a concern amongst university and industry representatives. The study was conducted by comparing the existing human resources and infrastructure in Indonesia and in China, where the industry keantariksaannya absorb hundreds of thousands of employees with very high qualifications. The capacity of the industry has made Chinese satellite successfully meet the needs in the country, and even began to sell abroad. Consortium formed satellite remote sensing research assessed the appropriate steps to mobilize national synergy, and it is advisable to also formed a consortium for the government telecommunications satellite. For the Ministry of Communications, the formation of the consortium will guarantee Indonesia's position in defending his orbital slots and frequency.


For human resource development, it is suggested that established centers of excellence in technology keantariksaan universities. In this regard Space agency recommended to make keantariksaan technology tree, in the context of Indonesia's needs, and identify scientific priorities and key technologies to be developed in universities and national research institutes, and seeking funding for the R & D-research and development. Assessment was made by comparing with petajalan and tree technology created by NASA, which is currently a key technology priority are: aerospace propulsion system, power supply system and battery space, navigation system and automatic control, astronaut support systems, sensor-based nanotechnology, as well as modeling and simulation. The key technologies R & D are then distributed to universities and research institutions of America.


One of the pioneering college to become a center of excellence in satellite technology is Negri Polytechnic of Surabaya (PENS). PENS launch satellite technology R & D program IINUSAT (Indonesia Inter University Satellite) is funded by the Ministry of Education in the 2009.Program continued to develop the nano satellite independently, and has resulted in the initial design and engineering modelpada 2012-2013. While the discussion of the infrastructure industry, PT. Indonesian Aerospace (DI) is considered to be one of the industry embryo keantariksaan Indonesia, because it has experience in the manufacture of satellite TV receiver systems. It is potentially considering VSAT population in Indonesia is in the tens of thousands, all of which are imported. FGD is planned in the future so that will be involved the participation of the Ministry of Industry, Ministry of Enterprise, and Bappenas.
