LAUNCHES

New Orbcomms launched, and they feel fine

Orbcomm Global, L.P. (Orbcomm) announced the successful launch of eight satellites into their target orbit approximately 825 kilometres above the Earth. This launch brings Orbcomm's LEO constellation to 20 satellites.

Orbital Sciences Corporation said that the new Orbcomm satellites are performing precisely as planned during early in-orbit check-out. As a result of data gathered from a series of initial spacecraft testing procedures, a team of Orbital and Orbcomm satellite engineers has determined that the main systems of all eight satellites are operating as expected.

At the present time, it has been determined that all eight satellites are generating the full electrical power levels for which they are designed, indicating that their solar arrays have properly deployed and are accurately tracking the sun. In addition, all eight satellites have been in reliable communications with Orbcomm's ground network in the United States

Over the next several days, a team of Orbital and Orbcomm engineers will continue to conduct a series of tests to confirm that the satellites are operating as planned and to make any necessary adjustments. Following this initial evaluation phase, the engineering team will conduct more comprehensive testing over the next three months in preparation for placing the satellites into commercial service.

When the new satellites are operational, Orbcomm will increase the communications availability in the U.S. from an average of nine hours per day to 17 hours per day. Orbcomm provides two-way monitoring, tracking and messaging services.

ST-1 on its way to Kourou

A satellite to be used by Taiwan and Singapore will be launched on August 25. ST-1 according to one of its operators is on its way to the European Space Centre at Kourou where it will be launched aboard an Ariane 4.

Chunghwa Telecom of Taiwan said that ST-1's footprint will cover China, India, Indonesia, Japan, Malaysia, the Philippines, Singapore and Sri Lanka. The satellite, built by Matra Marconi Space, will provide satellite services for local TV, broadcasting, telecommunication and internet companies. Chunghwa and Singtel of Singapure would operate seven C-band and eight Ku-band channels each.

SATELLITES

Yet another Iranian satellite

For over two years, Iran has been claiming it would soon launch a geostationary "educational" TV satellite by the name of Zoreh. The latest version was that the technology would be supplied by Russia. Now there's a smaller and much cheaper Iranian satellite venture: a multi-purpose satellite for just US$20 million.

Nonetheless, Iran needs the help of five other countries. According to Iranian media, representatives from China, Iran, Mongolia, Pakistan, South Korea and Thailand negotiating the "technical and financial" terms for the project to launch a satellite in 2001.

Iran says it's prepared to spend US$3 million to US$4 million, offering to build some ground stations. The only thing they had to offer for the satellite itself were--the batteries. Nonetheless, Iran through this venture expects to acquire the technology to built satellites.

LAW & ORDER

Hughes to pay military launch observers

Hughes Electronics is offering to pay for Defense Department monitoring of its launches of U.S. satellites on Chinese rockets, according to Hughes Vice Chairman Steven D. Dorfman. The offer came at a House subcommittee hearing looking into export licensing for communications satellites.

Dorfman said the 17 U.S. commercial satellites launched in China were guarded around the clock by security specialists before being sent into space. 14 launches had been monitored by U.S. Defense Department personnel. In three cases, DoD monitors were invited but did not turn up.

"The presence of DoD monitors is one more layer of protection that Hughes believes is well advised and one for which we, as a company, are willing to bear the financial burden if budget limitations are a problem," Dorfman said.

Dorfman also said that provisions should be made for the U.S. State and Defense departments to oversee any launch failure reviews. In 1996, a Commerce Department decision allowed Hughes to give China a report on a rocket launch that failed without first having the report reviewed by the State or Defense departments. Critics argue that the information contained in this and similar reports could have helped China improve military rockets as well.

SkyBridge demonstrates frequency sharing

There's not too much space in space. This especially applies to the available frequencies, and that's why non-geostationary orbit (NGSO) satellite systems will be allowed to share frequencies with geostationary (GSO) satellites in the Ku-band and the Ka-band. Will it really work? Yes, says the operator of the planned SkyBridge system.

SkyBridge says it conducted a demonstration of the impact of the WRC-97 (World Radiocommunications Conference) provisional power limits on direct broadcast satellite (DBS) systems at a recent International Telecommunications Union (ITU) meeting. Receiving live Astra and Hispasat programming signals via satellite with standard consumer equipment, SkyBridge demonstrated the absence of any perceptible impact on DBS viewers from NGSO operations under the WRC-97 power limits.

SkyBridge will use the Ku-band for its its global broadband access system that is to become operational by 2001.

At the ITU meeting, consensus was reached on use of new of a new methodology for evaluating the power limits applied to NGSO systems. The delegates also agreed on principles for software to be used by the International Telecommunication Union to confirm appliance of a NGSO system with the power limits. Progress was made in defining the appropriate protection for GSO and terrestrial systems and on the means of assessing the true effect of multiple NGSO systems.

FCC approves stratospheric platforms

Good news for Sky Station International, Inc., which plans to begin operating a high-speed, high-density wireless service via stratospheric platforms during 2001. The U.S. Federal Communications Commission (FCC) approved the use of stratospheric platforms as telecommunications stations. The ruling states that stratospheric platforms are expected to be the dominant use of 1000 MHz of spectrum (47.2-48.2 GHz). The frequencies will be auctioned later.

According to Sky Station, the FCC also noted that while it would not prohibit satellite companies from bidding for the frequencies, it recognised the existence of the decision of the International Telecommunication Union in November 1997 favouring use of the 47 GHz band world-wide for stratospheric platforms. Accordingly, the FCC said any satellite bidders would have to show that they would not cause any interference to stratospheric platforms.

The FCC also ruled that use of the spectrum would be flexible, which would allow the bands to be used for fixed, mobile and point to multi-point services. This will enable Sky Station to provide a wide range of services. The FCC declined to impose any foreign ownership limitation on stratospheric companies so long as the foreign owners were from WTO signatories or from countries which met trade reciprocity conditions.

Sat-ND has frequently reported about Sky Station's plans to operate a fleet of 150-metre long airships which, from an altitude of about 20 kilometres, will provide data and telephone services to areas of over 900 kilometres in diameter.
