Major Team Member Consists of:
Equipment to be used:
- NEC's VSAT Ku-Band Earth Station to catch the JCSat-3 signal.
- Latitude -6.5 [deg]
- Longitute 107.4 [deg]
- Azimuth 73.2 deg]
- Elevation 64.7 [deg]
- Antenna Diameter 3.6 [m]
- Outbound C/N 13.4 [dB]
- Inbound C/N 13.2 [dB]
- EIRP >= 55.3 [dBW]
- G/T >= 26.9 [dB/K]
- Modulation QPSK
- Information Rate 2.048 Mbps
- FEC R=3/4
- Router:
- HP Netserver LC
- Pentium Processor.
- 32Mbyte of RAM.
- 1Gbyte of Harddisk.
- FreeBSD OS - running latest verion of GateD to handle BGP-4.
- Riscom N/2 highspeed dual port I/F with RS449 connector.
NEC's VSAT Ground Station is currently on its way to Indonesia from Japan. The Router is obtained directly from HP Indonesia with the Riscom card ordered separately.
Construction Schedule:
May 1996
- Apply for license from the Ministry of Post and Telecommunication in Indonesia.
June 1996
- working on license with the Ministry of Post and Telecommunication in Indonesia.
July 1996
- Gateway room preparation.
August 1996
- Construction of the room for the gateway.
- Arrival & Installation of the PC Router.
- Arrival of the Ku-Band Ground Station (we strongly hope).
September 1996
- Erection of the Ku-Band Ground Station.
- getting the operational license from the Ministry of Post and Telecommunication.
October 1996
- Early test of the Ku-Band Ground Station.
Proposed Major Experiments:
- MBONE & Multimedia traffic over the AI3 satellite link is of interest. Preparation is currently underway by setting up:
- Reflector at ITB (temporary reflector at maingtw.paume.itb.ac.id).
- Experiment a little bit on CU-see-Me video conference.
- We would be interested to try other experiments.
- Weather would kill Ku-Band satellite link. Effort should be done to adaptively change the satellite speed to be able to penetrate the weather to the satellite. To perform this, we would need:
- Weather monitoring system to monitor the outside weather which then automatically tell the modem to lower the speed when bad weather.
- Spectrum analyzer at the input of the modem to see the power spectrum of the downlink signal to confirm the monitoring of the weather monitoring system.
- Computer control & program should be developed to be able to control the change of speed in real time through a backup link to Internet.
- Initiate a major educational and research gateway in Indonesia to be integrated into Indonesia's national data backbone. Some of the major activities are:
- Interconnection with IPTEK-NET the current Indonesia education and research network will be hopefully made via 4Mbps Jakarta-Bandung fiber optic link (one should negotiate with PT. Telekomunikasi Indonesia:-) ...
- Integration with various telecommunication operators to support the establishment of national education and research network would be possible.
- Training & seminar activities to prepare all universities to be integrated into Internet. There are more than 1000 universities in Indonesia - it is tough job by itself to convince the 1000 rectors that Internet is beneficial for education and research - not to mention the technical burden as not many Indonesian are expert in setting Internet link.
