NewSat’s Chief Technology Officer (CTO), David Ball, an executive focusing on scientific and technological issues within the organization, features in APB’s Satellite Special. He discusses the big changes within the satellite industry, as well as news that shakes and shapes the market.
Ball sketches out three growth areas and threats to the satellite market. Aside from that, he also provides an update on the Jabiru Satellite Program’s fleet of Ka band satellites.
NewSat is to date the largest independent provider of satellite communications/communications satellite (COMSAT) or artificial satellite stationed in space for the purpose of telecommunications in the Commonwealth of Australia, a country in the Southern Hemisphere comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands in the Indian and Pacific Oceans.
Newsat provides coverage to 75.5% of the Earth’s surface, including their satellites, VSATs (very small aperture terminals), a two-way satellite ground station or a stabilized maritime VSAT antenna with a dish antenna that is smaller than three meters, and teleports (telecommunications port), a satellite ground station with multiple parabolic antennas (i.e., an antenna farm) that functions as a hub connecting a satellite or geocentric orbital network with a terrestrial telecommunications network.

The C Band Interference
There is one issue that refuses to go away for the satellite industry. It is the C band interference.
ABS’s Chief Operating Officer Scott Sprague said “C band Wi-max issues and interference are always a worry.” He said that the satellite is used for lifeline-like services and then there is also the economic impact.
SES World Skies’s Senior Vice-President Deepak Mathur at SES agreed: “C band is an enormous issue and will be an ongoing issue. We have to remember 98% of video content in Asia is delivered by C band.”
The C band is the name given to certain portions of the electromagnetic spectrum which includes wavelengths of microwaves that are used for long distance radio telecommunications. The IEEE C band (4 GHz to 8 GHz) and its slight variations contains frequency ranges that are used for many satellite communications transmissions, some WiFi devices, some cordless telephones, and some weather radar systems.
The microwave frequencies of this band perform better under adverse weather conditions in comparison with others, especially Ku band (11.2 GHz tyo 14.5 GHz) microwave frequencies which are used by another large set of communication satellites. The adverse weather conditions, collectively referred to a rain fade, all have to do with moisture in the air, including rain and snow.

NewSat Towards the World
NewSat, Australia’s largest satellite communications company, is providing vital communications for Australian Defence personnel located in far-flung places. They are also now preparing to launch its very own communications satellite.
Mike Keneally, Vice-President of Satellite Strategy, speaks to Grant Smith about the company’s Government Accredited Adelaide and Perth teleports, the services the Teleports provide Australian and US Defence Force personnel and Jabiru-1, Australia’ first locally owned commercial satellite.

VSAT History
The concept of the geostationary orbit was originated by Russian theorist Konstantin Tsiolkovsky, an Imperial Russian and Soviet rocket scientist and pioneer of the astronautic theory. He wrote articles in space travel at the turn of the century.
In the 1920s, Hermann Oberth and Herman Potocnik, aka Herman Noordung, described an orbit at an altitude of 35,900 kilometers. Its orbital period, or the time for it to make one complete orbit about another object, exactly matched the Earth’s rotational period, making it appear to hover a fixed point on the Earth’s equator.
Arthur C. Clarke contributed to the understanding of satellites through an article published in Wireless World in October 1945 titled “Extra-Terrestrial Relays: Can Rocket Stations Give Worldwide Radio Coverage?” In this article, Clarke not only determines the orbital characteristics/elements, or the parameters required to uniquely identify a specific orbit, necessary for a geostationary orbit, but also discusses the frequencies and power needed for communications.
Live satellite communications was developed in the sixties by the National Aeronautics and Space Administration (NASA), named Syncom 1-3. It is transmitted live coverage of the 1964 Olympics in Japan to viewers in the United States and Europe. Soon after, on April 6, 1965, the first commercial satellite was launched into space, Intelsat I, nicknamed Early Bird.
The first commercial VSATs were C band (6 GHz) receive-only systems by Equatorial Communications using spread spectrum technology. More than 30,000 60 cm antenna systems were sold in the early 1980s. Equatorial later developed a C band (4/6 GHz) two-way system using 1 m x 0.5 m antennas and sold about 10,000 units in 1984-85.
In 1985, Schlumberger Oilfield Research co-developed the world’s first Ku band (12-14 GHz) VSATs with Hughes Aerospace to provide portable network connectivity for the oil field drilling and exploration units. Ku Band VSATs make up the vast majority of sites in use today for data or telephony applications. The largest VSAT network (more than 12,000 sites) was developed by Spacenet and MCI for the US Postal Service.

NewSat's Paldao on His Ka-Band Perception
"We are not trying to be all things to all people, but certain application such as ISR are an ideal fit for Ka-band." - Diego Paldao
Milsatmagazine (MSM) asked Diego Paldao, NewSat's Senior Director-Americas on his opinion about Ka-band, the one which covers the frequencies of 26.5-40 GHz, in the middle of all the varied perception.
Paldao said that Ka-band is the next generation of satellite technology as there's some forward thinking companies like: ViaSat, a DBS distributor and TV broadcaster, owned by Swedish media conglomerate Modern Times Group; DIRECTV, an American direct broadcast satellite service provider and broadcaster based in El Segundo, California; SES, a global satellite owner and operator based in Betzdorf, Luxembourg and is listed in the Luxembourg Stock Exchange and Euronext Paris under the ticker symbol SESG; and EchoStar Corporation, a technology company that is the owner and maintainer of the satellite fleet for closely affiliated Dish Network. These companies have been promoting and leveraging Ka-band capabilities for some time already. He believes that in the very near future, Ka-band will be more mature and understood in many new sectors.
"I think we will see a higher proliferation of Ka-band terminals due to higher demand, which will help drive down costs and standardize design, just like we saw with Ku-band," he said.
NewSat is to date the largest independent provider of satellite communications/communications satellite (COMSAT) or artificial satellite stationed in space for the purpose of telecommunications in the Commonwealth of Australia, a country in the Southern Hemisphere comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands in the Indian and Pacific Oceans.

In 1987, NewSat was founded by its CEO Adrian Ballintine and the co-founder of the Microsoft Corporation, an American multinational corporation headquartered in Redmond, Washington, United States, that develops, manufactures, licenses, and supports a wide range of products and services related to computing, Paul Allen, an American investor and philanthropist. The company started as a multimedia business. It survived the dotcom crash/bubble (also referred as the "Internet bubble" and the "Information Technology Bubble"), a historic speculative bubble covering roughly 1995-2000 (with a climac on March 10, 2000, with the NASDAQ peaking at 5132.52 in intraday trading before closing at 50048.62) during which stock markets in industrialized nations saw their equity value rise from growth in the Internet sector and related fields, to evolve into a fully-fledged satellite communications company. Most NewSat customers are located in Australia, the Middle East, a region that encompasses Western Asia and all of or part of Northern Africa, depending on the context; Africa is the world's second largest and second-most-populous continent, after Asia.
