stoweboyd: Air-powered hybrid car unveiled. Peugeot Citroen have shown off a hybrid car which can run on petrol or compressed air, or a combination of both. The ‘Hybrid Air’ system uses a petrol engine for travelling at ‘cruising’ speeds, where the makers say petrol is still the most efficient power source. At slower speeds or when the vehicle needs extra power to climb a hill, the car uses a combination of compressed air and petrol. At slower speeds below 43mph the car runs solely on compressed air until the supply runs out. The air tanks are refilled during all modes of driving, by re-using energy normally lost during slowing down and braking, instead using that energy to run an air compressor. The makers claim an average fuel saving of 45 percent, and when driving solely around cities at slower speeds that figure could rise to 80 percent. The car is expected to be available by 2016.

SpeedCast acquires Australian Satellite Communications

One of the leading telecommunications providers in Asia, Africa, and the Middle East acquired Adelaide-based Australian Satellite Communications. SpeedCast, with offices in Hong Kong, Malaysia, and the Middle East, has completed its purchase of ASC, as part of its strategy for global expansion and growth.

ASC has been delivering satcom services to various sectors down under, including the mining, oil and gas, and construction industry. Maritime vessels and government agencies also rely on the company for network solutions.

SpeedCast on the other hand, delivers managed network services to 30 countries and boasts of an international presence along with operating 16 teleports across the globe. The company has been leveraging satellite communications technology to provide powerful and reliable networks across its target regions, and the latest acquisition will see SpeedCast penetrate the all-important Australian market.

Australia the center of interest with satellite project

The Australian Square Kilometre Array or SKA project has already attracted interest from researchers and scientists across the globe even before it was officially announced this morning.

The radio telescope project, which extends in regions in the Southern Hemisphere, in particular South Africa and Australia, will operate at wide-range frequencies and provide high-resolution astronomical images. The region has the best view-angle for the Milky Way galaxy and has the least radio interference.

Over 350 researchers from 150 institutes and organizations have already booked at SKA which is schedule for construction on 2016, and full operation by 2024. For the first five years of operations, the project has already been booked for its satellite telescope technology which will capture vivid images of the sky in large sections.

Researchers plan to use the facility to study black holes and magnetic fields, although the search for extraterrestrial life could be a byproduct of the experiments to be conducted at SKA.

Still no earth observing satellites for Australia

In the Southern Hemisphere, Australia is one of the more remote regions despite its size, and many states of the nation-down-under are spread across vast expanse of uninhabited lands. Despite this, the country still depends on other nations for the technology of earth observing satellites critical not only to the country’s security but also for basic public purposes. 

Satellites are also essential in monitoring the weather, mapping out geographic hazards, and assessing the various resource sectors of the country including water, mining, oil and gas.

Australia has depended on satellite information and data - which is free and paid for by the taxpayers of the nations where we source them, like Singapore, Malaysia, Nigeria and Morocco. The country has the economic capability but still doesn’t have its own earth-observing satellite.

One of its satellite communications company, NewSat, is set to launch the country’s first satellite into space via the Jabiru Satellite Program, however it’s primary purpose is to deliver ka-band capacity for communications solutions. 

Economic certainty across the globe may push Australia to focus on having its own EO satellite. Financial crises have an impact on how the free data is collected, and because of the uncertain economic climate, many satellite launches have already been delayed. 

Many scientists and experts are saying the Australia must act fast since critical information like water run-off from forests depend on such actions.

Features of Satellite Broadband

Bandwidth pertains to the amount of data that is sent and received by ISPSs and satellite broadband companies. This amount is measured in terms of megabits per second, or roughly one million bits per second.

There are approximately 300 satellites located on a fixed geostationary orbit, just above Earth’s equator, with 2-3 degrees distance in between. These satellites move withthe world at the same speed. Ground stations can locate geostationary satellites at a fixed location relative to the globe’s equator.

Three things should be carefully considered when evaluating the capacity of satellite carriers: downlink EIRP power (dBW), transponder bandwidth (MHz), uplink G/T (dBK) and sensitivity (dBW/^m2), which is bought by ISPs and satellite operators.
