AMOS-4, built by Israel Aerospace Industries (IAI) for Spacecom, was successfully launched saturday night (August 31, 2013) from Baikonur, Kazakhstan, aboard a ZENIT 3SLB launcher. This morning (September 01, 2013) the satellite separated from the launcher’s last stage and has started communicating with the ground control station and mission control. IAI engineers have started Transfer Orbit operations.

During the coming three weeks, AMOS-4 will continue its transfer orbit until arriving at 67.250 East, where In Orbit Test will be conducted before continuing to its designated permanent service location at 650 East.

IAI President and CEO Mr. Joseph Weiss said from the launch site: “We feel very proud of AMOS-4, which reaffirms IAI’s position as a world class satellite provider with industry leading capabilities in observation and communication satellites.”

Spacecom President and CEO Mr. David Pollack said: “AMOS-4 continues Spacecom’s tradition of providing top quality satellite solutions primarily for emerging markets and is another milestone for the company. We are continuing to maintain our fast growth as we push to become a major player in our markets and expand and extend our reach in becoming a global satellite operator. Working with IAI throughout the process has been a blessing and we look forward to further cooperation with them.”

The onboard communications payload provides many advanced capabilities and features including flexible coverage by using steerable antennas. The payload features wideband and high-power transponding capabilities and enables the use of an agile frequency plan and flexible capacity allocation per beam. It supports multiple services, including traditional and next-generation Broadcast services, and emerging Interactive services and Mobile services. In addition to the advanced flexible microwave repeater, the payload employs a digital payload for carrier-level processing and flexible transponding. The system performance enables very high Quality of Service (QoS) for advanced services, including low-power small and mobile users.

AMOS-4 weighs 4.3 ton at launch, and has a 6 KWatt electrical power subsystem.

The AMOS-4 satellite is based on the AMOS 4000 platform, which introduces a modular design architecture. It is composed of three (3) modules – Bus module, Repeater module, and Earth Facing Antennas module. The Amos4000 bus features very high efficiency (payload / bus ratio) and extremely accurate pointing and stable coverage that are critical for large diameter Ka antennas. The bus is scalable to host configurations between 3 and 12 KWatt and 2.5 to 5.5 tons. The Amos4000 bus also features highly autonomous capabilities as well as an advanced Telemetry, Command and Ranging (TCR) system. Amos4000 bus was designed to be compatible with most available launch vehicles.

The Amos4000 will be used for the AMOS
