LightSquared touts new tests prove its internet service will not interfere with GPS
In a press event today, LightSquared announced that just-completed tests prove that its internet service will not interfere with GPS.
According to the company, the three private companies — Javad GNSS, PCTel and Partron — that make GPS equipment have been testing interference solutions and those tests have gone well. “Preliminary results show that GPS devices tested in the lab easily surpass performance standards thanks to these newly developed solutions,” Ahuja said. “We are confident that this independent testing will mirror testing being done by the federal government.”
Here’s another perspective:
Jim Kirkland, vice president of Trimble and a founding member of The Coalition to Save Our GPS, is trying to slow LightSquared’s momentum. “It is obviously extremely premature to claim at this point that these latest tests demonstrate that LightSquared’s proposed repurposing of the mobile satellite band for terrestrial operations is ‘compatible’ with high-precision GPS,” Kirkland says in a statement. “Even if new equipment solutions are fully tested and verified, these existing high-precision receivers will have to be retrofitted or replaced. LightSquared still refuses to accept the financial responsibility for addressing interference to existing devices, and so has not offered a comprehensive solution in any way, shape, or form.”

An experiment designed to mimic the dynamo at the Earth’s core is about to be turned on.
Mad scientists at their best! An experiment designed to mimic the dynamo at the Earth’s core is about to be turned on.
Ten years in the making, the US$2-million project is nearly ready for its inaugural run. Early next year, the sphere will begin whirling around while loaded with 13,000 kilograms of molten sodium heated to around 105 °C. Researchers hope that the churning, electrically conducting fluid will generate a self-sustaining electromagnetic field that can be poked, prodded and coaxed for clues about Earth’s dynamo, which is generated by the movement of liquid iron in the outer core. If it works, it will be the first time that an experiment that mirrors the configuration of Earth’s interior has managed to recreate such a phenomenon.
This is a really very cool experiment, as we really do not have a good understanding of how planetary magnetic fields are produced.

Electric car company shuts down
For once, the taxpayer doesn’t get screwed: The electric car company Aptera has shut down due to lack of interest from investors and the lack of a loan from the government.
The California company was counting on a federal loan – and private investments to match the loan – so that it could start producing its very first electric vehicle. Aptera said it was close to securing a $150 million from the U.S. Department of Energy, but it couldn’t line up the private dollars necessary to complete the loan application process.
Uganda’s suborbital spaceplane, under construction in the backyard of the designer’s mother
Uganda’s space program: the construction of its first aircraft — in the backyard of the designer’s mother’s home — to be followed by a space shuttle! With pictures and video.
At first glance this looks absurd and a pipe dream. However, stranger things have happened. I wish them all the success in the world.
