Newtec with Iraqi satellite broadcaster Alsumaria
Such is the case for Newtec with Iraqi satellite broadcaster Alsumaria — that company has reached the third stage of its investment in Newtec’s modulation equipment with DualFlow™ and FlexACM® technologies, as part of its migration towards tapeless news production. Since 2004, Alsumaria has established itself as one of the most dynamic and popular broadcasters in Iraq. The latest stage of its infrastructure project involves the installation of DualFlow and FlexACM in its fleet of DSNG units for increased productivity, faster delivery of news content and reduced costs. Alsumaria’s fleet can now deliver live transmission of MPEG-4 over IP, with the dual capability of switching to ASI when required, thanks to DualFlow. Staff can also achieve file transfers and downloads between the DSNG units and the production centre, increasing speed of response to unfolding events. DualFlow technology further increases the productivity of DSNG crews by enabling VoIP connection with the studio, together with e-mail and broadband Internet. Alsumaria’s implementation of Newtec’s FlexACM in its DSNG fleet gives the broadcaster an extended reach in the satellite footprint, with five occasional use slots achieved in only 4MHz. The modems with FlexACM functionality allow high speed file transfers between the DSNG and the studio/playout/editing site. The Newtec EL810 Mobile PEP-Box® Terminal was added to achieve file transfers adding compression and real broadband experience.
Alsumaria’s homepage…DualFlow modems give Alsumaria TV the ability to deliver MPEG-4 live streaming and to store and forward video files. The Newtec solution provides comprehensive control of the quality of service and higher dedicated throughput than traditional VSAT (shared MF-TDMA) systems, together with lower delay, higher availability and better throughput. DualFlow allows broadcasters to transport IP over satellite in the most efficient way, either separately or in combination with traditional ASI live streams on the same carrier. DualFlow supports both IP and ASI interfaces, allowing broadcasters to make the transition to IP connectivity at any time. When used on a modem, DualFlow fully enables two-way IP interactivity over satellite, making it possible to introduce new services into the broadcast workflows, such as real-time interviews, VoIP coordination channels, file upload and download, and remote access to tapeless production infrastructures. By turning DSNG vans into remote offices, DualFlow increases the productivity of the remote teams.
Thuraya Locate – satellite location service
TS2 Satellite Technologies has announced the launch of Thuraya Locate. The service is for people who want their location to be known and shown to family, friends or employers so that they know where the user is, where they have been and when. It is a simple and easy service which allows anyone that you wish to see your location and history using essentially any recent web browser on any current PC.
ThurayaLocate service relies upon Thuraya satellite phones to transmit their GPS location data; hence ThurayaLocate™ operates in all countries where Thuraya satellite phones operate. Currently in satellite mode this represents almost 2/3 of the world’s land surface including Asia, Africa, Europe, Middle East, China, Indonesia, Japan, Korea and Australia. When using a Hughes, Ascom, SG or SO phone the Thuraya Location Services are also available wherever there is an interconnected GSM network, thereby significantly extending the coverage area.
The service works by:
• The Thuraya subscriber registering their handset for the ThurayaLocate™ service via www.thurayalocate.com
• Upon registration, the subscriber will receive a username and password to access the service. The subscriber decides which authorized people they will share the username and password with.
• After registering, the user acquires their GPS position using the standard features available on Thuraya handsets.
• This information is then sent manually via SMS to the ThurayaLocate operations center.
• The authorized parties log on to the website with the subscriber username and password.
• The web browser displays the handset location using maps, satellite images and aerial photography made available via Google Maps or Windows Virtual Earth.
ThurayaLocate™ is designed for:
Backpackers letting friends and family see where they are and where they’ve been
Outdoor adventurers – skiers, hikers, mountain bikers, climbers, canoeists, coastal and oceanic sailors
Balloonists, paragliders and light aviation pilots
Fishing fleets, coastal and oceanic cargo ships, water taxis, ferries, river and cruise boats
Long distance drivers, truckers and courier companies
Government ministers and staff on overseas assignments
Corporate clients working in remote locations
Oil/gas/mineral exploration teams
Pipeline, road, rail and GSM network construction teams
Overland travel companies, tourist coaches, 4×4 rally enthusiasts
World Bank, United Nations and agencies working in developing markets
Disaster relief agencies – forest fire, flood, tsunami, earthquake
Anyone travelling and working in off-the-beaten-track locations who wants friends, family and/or their employer to know where they are.

DARPA eyes space-based Internet for persistent battlefield data communications, surveillance, and satellite control
Satellite communications experts at the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., are taking the next step in developing broadband data communications links to orbiting satellite constellations, not only to establish persistent SATCOM capability for fighting forces in the field, but also to enable real-time control of satellites from military theaters of operation.
The ability to control clusters of satellites from military theaters of operation like Iraq and Afghanistan not only could help establish predictable, round-the-clock satellite communications links for forward-deployed warfighters, but also has the potential to help establish controllable, persistent surveillance capability for the military commanders in the field who need it most.
DARPA awarded an $18 million research contract Friday to Inmarsat plc in London for the Persistent Broadband Ground Connectivity for Spacecraft in Low Earth Orbit program, which seeks to enable near-24/7, very-low-latency, on-demand broadband connectivity between ground satellite terminals and spacecraft in low earth orbit (LEO).
This capability could help establish a persistent communications system for LEO satellites for time-sensitive spacecraft control for defense maneuvers, rapid transmission of critical mission data such as space weather events, direct-from-theater control of spacecraft, and direct-to-theater data delivery with a small ground-based transceiver.
Researchers from DARPA and Inmarsat will use the Broadband Global Area Network (BGAN) service from Inmarsat’s I-4 satellite communications constellation to help develop and demonstrate technology for this program. The BGAN service is the fastest mobile data link available that uses a portable terminal and offers on-demand connectivity with global coverage that could extend to LEO orbital altitudes, DARPA officials say.
The BGAN network, which serves land-based, shipboard, and aircraft satellite communications, provides 492-kilobit-per-second full-duplex, full-channel bandwidth over about 600 spot beams with 588 channels per beam.
A space-based BGAN terminal for LEO use appears to be technically feasible by making modest adaptations to the airborne terminal involving Doppler compensation, radiation hardened components, and software changes for rapid beam-to-beam handover without loss of service, DARPA officials say.
For the Persistent Broadband Ground Connectivity for Spacecraft in Low Earth Orbit program, Inmarsat engineers will design a space-based BGAN terminal, modify the BGAN, perform hardware-in-the-loop tests of a space-based BGAN terminal, and integrate the space-based BGAN terminal with the System F6 fractionated spacecraft demonstration cluster.
