The Pegasus Push
Orbital Sciences Corporation successfully launched the company-built Nuclear Spectroscopic Array Telescope (NuSTAR) satellite for the National Aeronautics and Space Administration (NASA) into its intended orbit.
The Stargazer carrier aircraft taking off from Kwajalein Atoll in the South Pacific on its 27th successful Pegasus mission. Pegasus has launched from six different sites worldwide, the first time a space launch vehicle has demonstrated such operational flexibility.
The Pegasus/NuSTAR mission originated from the U.S. Armys Reagan Test Site, Kwajalein Atoll, which is a part of the Marshall Islands in the mid-Pacific Ocean. Following a one-hour preplanned positioning flight, the Pegasus rocket was released from Orbitals L-1011 carrier aircraft at approximately 12:00 p.m. (EDT). After a 13-minute powered flight sequence, Pegasus launched the 770 lb. NuSTAR satellite into its targeted circular orbit approximately 400 miles above the Earth.
Orbital designed, manufactured and tested the NuSTAR satellite at its Dulles, Virginia, satellite manufacturing facility. The Pegasus rocket was assembled and tested at company facilities at Vandenberg Air Force Base, California. Todays successful launch by the Pegasus rocket was the 27th consecutive successful mission for the Pegasus program over a 15-year period and the 41st overall flight of the companys unique air-launched system since its introduction in 1990.
Mr. Ron Grabe, Orbitals Executive Vice President and General Manager of its Launch Systems Group, said The NuSTAR program is another dual mission for our launch vehicle and satellite engineering teams, building on our history of supporting successful NASA scientific programs such as AIM, GALEX, SORCE, ACRIMSAT and IBEX with our launch vehicles and satellite platforms.

Newtec has ushered in a new era of bandwidth efficiency by breaking the magical 0.5 Gbps two-way throughput over a 72 MHz transponder on a Eutelsat satellite.
Testing was performed at Eutelsats teleport in Rambouillet during the night in order not to disturb crucial daytime sport transmissions. A significant margin was taken in cloud cover conditions to ensure the tests were relevant for real-life high availability service.
In the two-way high speed backbone tests, Newtec combined its Bandwidth Canceler and Next Generation modems (Newtec MDM6000 series) to achieve a staggering 506 Mbps (2 x 253 Mbps).
Innovative elements were used, including Clean Channel Technology® (a Newtec technology for implementing lowest roll-off and filtering to boost throughput). New modulation and Forward Error Correction (FEC) codes were also used, which can be seen as demonstrators for evolutions in extending the DVB-S2 standard. In particular for this part of the test, a complete reworked 32 APSK 135/180 (135 over 180) modulation proved to be most optimized.
In another test, 352 Mbps was achieved in a one-way distribution set-up over the 72 MHz transponder using 64 APSK modulations and related codes, with significant margin on the Ku-band system.

WORK Microwave has debuted their new DVB-S2 Modem SK-DV.
Using DaVid technology, the device offers simultaneous transportation of data (network connection) and live broadcasting (video content) over a single satellite carrier. The DaVid technology works by aggregating multiple MPEG transport streams and IP data into a single baseband stream, called multistream, which is then inserted into a broadcast modulator.
The single carrier signal is transmitted via satellite by the modulator and then received by multiple receivers that separate and extract specific content parts based on their DVB-S2 Input Stream Identifier (ISI).
The DaVid technology configures all DVB-S2 baseband parameters independently for each stream, providing users with the flexibility to choose the number of streams that need to be processed.
The combined modem includes several features and capabilities designed to provide users with maximum bandwidth efficiency and data throughput at all times. The DVB-S2 Modem SK-DV uses Generic Stream Encapsulation according to TS 102 606, which ensures the device is compatible with products from other providers compliant to the DVB-S2 standard and allows users to easily incorporate the modem into existing operations.
Additionally, advanced modulation up to 32APSK offers the most efficient satellite communication for dedicated links, enabling broadcasters to deliver reliable, flawless transport.
Multichannel ACM functionality (OptiACM) compensates for disturbances in the satellite link due to physical conditionssuch as humidity and atmospheric precipitationthrough real-time adaptation of transmission parameters according to link conditions, improving data throughput in all usage cases and under all environmental conditions.
Additionally, the DVB-S2 Modem SK-DV optimizes the amount of usable bandwidth through a traffic shaping capability that controls the volume of traffic being sent over satellite and determines minimum/maximum data rates for each content type. Traffic is differentiated into groups and prioritized with respect to a number of configurable parameters.
Built on a cross-layer system design that applies interlayer communication exchange across the protocol stack, the DVB-S2 Modem SK-DV operates at an efficient data rate of up to 160Mbps, supporting high-speed data transmission so broadcasters can deliver live high-definition video content over a satellite linkin addition to Internet file transfer.

Second Jack-Up Contract
Imtech Marine (Radio Holland Netherlands) has been awarded an extensive contract from Jack-Up Barge for the communication and IT systems for its newbuild, self-elevating platform JB-118.
This follows a similar contract for the JB-117, which Imtech Marine successfully completed earlier this year. Additionally, Jack-Up Barge and Imtech Marine have concluded an Advanced Support Agreement for the vessels, which includes 24/7 remote Monitoring & Maintenance and covers all of the systems onboard.
The recently awarded contract for the latest barge is extensive comprising the PA intercom and alarm system, VSAT network, PABX central telephone system and the total navigation, communication and entertainment package, including IPTV and satellite television. Additionally, Imtech Marine will install VHF/UHF communications for the crane operators, a meteo and CCTV system, as well as a communications system for the helideck.
Nico van Leeuwen, Imtech Marine Netherlands Sales & Marketing Manager, says the two companies started to work together around 18 months ago on the JB-117, which was built in Batam, Indonesia. The JB-117 was a difficult installation, very complex; our knowledge gained from this project has provided valuable input for the JB-118 and any future orders.
One aspect that makes the installation quite challenging is that the barge typically has 50 to 80 crew onboard of different nationalities and of course, they would all like to watch their favorite TV shows on different stations.
Paul Koole, Project Manager E&I, Jack-Up Barge, said, The JB-117 is working on a three-year contract on a wind farm in the North Sea. Jack-Up Barge recognises that this access to television and the Internet is very important for crew welfare.
Jack-Up Barge has taken out an Advanced Support Agreement for the vessels, which includes 24/7 remote Monitoring & Maintenance and covers all of the systems onboard, including VSAT, computers, navigation and communication equipment. As the barges are often working offshore for many months at a time it is vital that any problems can be sorted out remotely. This agreement also includes systems management. For instance when there are crew changes and a new crew is boarding everything is set up ready, email accounts, login passwords etc. so they dont have to worry about changing the systems themselves.
Imtech Marine has already started on the pre-engineering and the drawings for the JB-118, which is being built near Hong Kong in Shenzhen and installation work is likely to start in the third quarter. The JB-118 is expected to be delivered mid-2013.
Jack-Up Barge is one of the worlds leading suppliers of Self Elevating Platforms for both the energy and heavy civil construction markets. Based in Sliedrecht in the Netherlands, Jack-Up Barge supplies two types of Self Elevating Platforms, the Modular and Monohull Jack-Up.
