The Trump Administration just revived the Cold War-era Space Command
Today, President Trump and Vice President Pence announced the return of the US Space Command -- a Cold War-era division of the Air Force that's been on a 17-year hiatus. The revival of the US Space Command is meant to "ensure the protection of America's interests in space," Defense Secretary Mark Esper said at a news conference Wednesday. But it could be confused with Space Force -- the sixth branch of the military that Trump hopes to create -- or the existing Air Force Space Command, which focuses on Air Force operations in space.
France is creating a space command to defend its satellites
The US isn't the only country that wants to create a dedicated space force within its military. French President Emmanuel Macron has greenlit plans to create a space command within his country's air force next September. The division would bolster defense of France's satellites, he said. Officials had yet to determine the scale of the investment.
Trump asks for $9.6 billion to bolster cybersecurity in 2020 budget
President Donald Trump has revealed his proposed budget for the 2020 fiscal year, which "supports the creation" of Space Force (USSF) as the sixth branch of the armed forces. The White House also hopes to bolster cybersecurity and NASA exploration missions.
US Air Force raises concerns over LightSquared's LTE network messing with GPS
Following a navigation system's instructions without driving into a ravine is hard enough as it is -- can you even imagine how hard it'd be if you kept losing GPS reception every time you drove within range of an LTE tower? There have been a few anecdotal concerns raised over the last several weeks that LightSquared's proposed LTE network -- which would repurpose L-band spectrum formerly used for satellite -- is too close to the spectrum used by the Global Positioning System, leading to unintentional jamming when the towers overpower the much weaker GPS signals. Things have gotten a little more interesting, though, now that the US Air Force Space Command has officially piped in. General William Shelton has gone on record saying that "a leading GPS receiver manufacturer just ... has concluded that within 3 to 5 miles on the ground and within about 12 miles in the air GPS is jammed by those towers," calling the situation "unbelievable" and saying he's "hopeful the FCC does the right thing." Presumably, the USAF thinks that "the right thing" would involve pulling LightSquared's license, but for its part, the company says it believes Shelton is referring to a test conducted by Garmin (possibly explaining that recent outage in the Southeastern US?) using simulated interference filters -- not the actual filters that it has spent several million dollars developing and perfecting. Regardless of how effective the filters might be, the idea that the only thing standing between a functional GPS system and a constellation of space-borne paperweights is a private company's privately-developed, privately-operated filtering equipment... but then again, we love LTE. Decisions! [Thanks, Brian]
