Overview
 

The IPSTAR Broadband Satellite system utilizes advanced technological concepts in conjunction with a new geo-stationary satellite to provide bandwidth capacity unmatched by conventional satellite technology. The system is radically different from currently available options in that it will target the Internet, the “Last Mile” sector and the mass consumer market in the same instance.

Shin Satellite Plc., a leading satellite operator in Asia and the promoter of the IPSTAR Project, developed and commercialized both the Space Segment and the Ground System ensuring that the IPSTAR system is a cost-effective, total solution for broadband last-mile communication. Competitiveness with other existing last-mile broadband solutions (such as DSL or cable modem) is guaranteed.

The IPSTAR satellite can deliver approximately 45 Gbps of aggregate capacity, far higher than conventional satellite, allowing it to satisfy the enormous demand for broadband Internet bandwidth of millions of users - consumers, corporate customers, service providers and telecom operators alike. The key benefits of the IPSTAR system are its ability to provide an immediately available, highcapacity ground network with affordable bandwidth and end-user terminals. The system will allow for rapid deployment and flexible service locations anywhere within its extensive footprint.

The IPSTAR commercial rollout strategy is divided into First Generation (FG) and Second Generation (SG):

• IPSTAR First Generation (FG) Service: The IPSTAR New Ground System is to be used in conjunction with conventional satellites. This will allow earlier deployment and ramp up of the IPSTAR service with reduced costs compared to other existing ground technologies.
• IPSTAR Second Generation (SG) Service: The IPSTAR Ground System will be used with the new IPSTAR-1 broadband satellite. The service is expected to commence in 2004, providing coverage all over the Asia-Pacific region. This will provide a very cost effective structure compared to any other existing satellite systems.

IPSTAR is a broadband satellite designed for today and future.

 
 
IPSTAR Technology

Space Segment: the IPSTAR satellite

• New “Cellular” multiple spot beams to increase bandwidth from frequency re-use with new antenna design technology to make such multiple beams possible.

• New Dynamic Power Management system to optimize each beam’s power output to suit weather conditions, thus increasing on board power efficiency and maintaining excellent link-availability for each
beam.

On the Ground: the IPSTAR Ground System

• Advanced Coding and Modulation technology to increase bandwidth and reduce power consumption (consequently reducing earth-station size, power requirements and hardware costs).

• Advanced Transmission Architecture for both uplink and downlink to provide a common platform for sharing bandwidth among many users, making it suitable for the asymmetric and intermittent nature of the Internet.

• Dynamic Link Allocation system to adjust modulation, coding and gain on an individual terminal basis according to prevailing weather conditions, thus maintaining a very high link-availability.
