ProtoStar 1 satellite: beam coverage maps

The ProtoStar I satellite was built by Space Systems/Loral (SS/L) as the ChinaSat-8 satellite. On January 5, 2007 SS/L announced the satellite, which had been in storage, would be modified to meet ProtoStar's requirements.

Launched July 7, 2008. ProtoStar I was placed into its geostationary orbital location of 98.5 degrees East Longitude.

Following the sale of ProtoStar I in bankruptcy auction, October 29, 2009, and the completion of the sale to Intelsat for $210M, the satellite was re-named Intelsat 25.

Intelsat 25 will serve for African market at 31.5 West orbital location.

It will carry 36 high power C-band transponders and 16 Ku-Band transponders.

Satellite broadcasting (DTH)

The Teleport facility in Cyprus provides a full portfolio of media and broadcasting services including:
• Uplink Service
• Full media playout service
• Playbox service
• Time shift service
• Standards conversion service

DVB-S & DVB-S2 IP download (one-way via satellite) service

Traditionally .... has provided IP downstream bandwidth via DVB-IP platform. .... C-band is a good platform for the provision of such a service due to its extended powerful coverage of the Middle East, India, Indian Ocean and South East Asia territories. This service is specifically designed for ISPs or corporate customers that have high demand in download traffic. It can be combined with any upstream technology including leased line, fibre or satellite SCPC to effectively increase the download capacity of the end user in a rapid and cost effective manner. It can also be used for real-time multicasting services e.g. stock market information, digital signage etc. By using advanced coding techniques on DVB-S and DVB-S2, .... will be able to provide throughout the coverage areas, downstream IP capacity of up to 60Mbps with the use of 1.8m-2.4m dish sizes.

VSAT broadband internet service (two-way via satellite) using iDirect technology

Consumers, enterprises and other organizations rely on more bandwidth intensive applications today more than ever before. Supporting these broadband needs means meeting new challenges, particularly geographic constraints, and integration with existing platforms. To insure networks meet all user needs, regardless of location or application requirements, they need to combine broadband speeds, easy integration, and advanced network management. iDirect Technologies supports the highest TCP/IP throughput in the satellite industry, with speeds up to 18 Mbps downstream and 4 Mbps upstream. This combined with the bandwidth efficiency and the inherent flexibility of the iDirect platform provides users with all the functionality of traditional broadband networks beyond any geographic constraint.

.... will launch in the coverage area of ... a new iDirect platform supporting all the latest features including DVB-S2 outbound capability. The powerful C-band beam of .... will allow the provision of VSAT iDirect based services to stations equipped with antennas as small as 1.2m diameter and 2W C-band BUC. This will definitely revolutionize the market as C-band is far more reliable in the tropics where hi rainfall causes constant stability issues to Ku-Band based services.

Applications of this service include:

• VoIP Backbone
• IP Backbone.
• Rural Telephony.
• VNO.
• GSM Backhaul.
• Broadband Access.
• Corporate network applications.
• Secure Telecommunications.
• Disaster Recovery/Business Continuity.
• Corporate network expansion.

• Voice, data, Internet & Video Connectivity independent of ground infrastructure.
• SCADA & Control Systems for remote monitoring of industrial installations:
Energy Production, Manufacturing.
• Interoffice/Intershop connectivity for data & Voice.
• Broadband Access & Wireless networks expansion.
• Maritime operations, Telephony, Fax, email & Internet for vessels in SE Asia trading routes.
• Secure Telecommunications.
• Real-Time Connectivity & Data from international markets.
• Remote Health care and humanitarian support to remote areas.
• Education & Research Programs in southeast Asia.

VSAT connectivity services - SCPC - point to point, star and mesh networking

Suitable for demanding applications requiring dedicated satellite capacity, such as voice telephony (incuding VoIP) termination, dedicated IP bandwidth and media applications (TV & radio linking).

.... has the capability of supporting dedicated SCPC VSAT design and implementation, regardless of the technology that will be used for this purpose. With its state of the art baseband network combining the best in SCPC satellite modem technology and backbone connectivity, .... combined with the excellent coverage of ... C-band capacity can offer the most complete and cost effective solutions in dedicated satellite connectivity whether it is internet, telephony or point to point.
