Thaicom-4 (IPSTAR) is a multiple spot beam bent-pipe satellite without on-board regenerative payload. The combination of innovative ground and space technologies allow the delivery of cost-effective satellite broadband for any location without access to terrestrial infrastructures. Thaicom-4 (IPSTAR) is the first high throughput satellite ever launched.
The IPSTAR broadband satellite system is composed of a gateway earth station communicating over the satellite to provide broadband packet-switched communications to a large number of user terminals with network star configuration.
Traditional satellite technology utilizes a broad single beam to cover entire continents and regions. With the introduction of multiple, narrowly focused spot beams and frequency reuse, IPSTAR is capable of maximizing the available frequency for transmissions; thus improving efficiencies and increasing bandwidth by a factor of twenty compared to traditional Ku-band satellites.
