Navy Fearing Hacks, Is Returning To Celestial Navigation

From The Telegraph:

…now the US navy is reinstating classes on celestial navigation for all new recruits, teaching the use of sextants – instruments made of mirrors used to calculate angles and plot directions – because of rising concerns that computers used to chart courses could be hacked or malfunction.

“We went away from celestial navigation because computers are great,” said Lt. Cmdr. Ryan Rogers, the deputy chairman of the naval academy’s Department of Seamanship and Navigation. “The problem is there’s no backup.”

GPS Workaround From DARPA


When the satellites we rely on for navigation can’t be reached — whether they’ve been jammed or you’re in a densely packed city — the chip contains everything you’ll need to figure out how to get from place to place. It’s got gyroscopes, accelerometers and a master clock, to calculate orientation, acceleration and time. The TIMU is fabricated from silicon dioxide and contained within a 10 cubic millimeter package — meaning it can just about fit within the Lincoln Memorial rendered on the back of a penny.

4th Amendment Under Attack Yet Again

This stuff is serious. Maybe most of the “People” protected by the Constitution do not have enough imagination to see how terribly wrong this is going to go for all of us, and I mean ALL of us. Well, I can imagine it because I’ve worked for governments, I know what they are capable of, and I promise you it will not be good. To quote Bogey, “maybe not today, maybe not tomorrow, but soon, and for the rest of your life”,  if you can call existence in a police state a life. Think this is hyperbole? We’ll see.

I know first hand that getting warrants can be a pain in the ass, but too bad, its our job to defend and protect the constitution, not whine about how hard it is to do our jobs and still abide by the “current” law, or to look for shortcuts and ways to get around the only document that stands between freedom and totalitarianism.

But don’t worry, I’m clearly over reacting because if I wasn’t, those vigilant watchdogs of the Fourth Estate would surely mention the trampling of our fundamental freedoms in their newspapers, websites and TV news shows, wouldn’t they?

Here is the latest assault on our freedoms from the EFF

DOJ Official: Any Privacy Protection is Too Much Privacy Protection for Cell Phone Tracking

Jason Weinstein, a deputy assistant attorney general in the Department of Justice’s criminal division, told a panel at the Congressional Internet Caucus Advisory Committee’s “State of the Mobile Net” conference yesterday that requiring a search warrant to obtain location tracking information from cell phones  would “cripple” prosecutors and law enforcement officials. We couldn’t disagree more.

For years, we’ve been arguing that cell phone location data should only be accessible to law enforcement with a search warrant. After all, as web enabled smart phones become more prevalent, this location data reveals an incredibly revealing portrait of your every move. As we’ve waged this legal battle, the government has naturally disagreed with us, claiming that the Stored Communications Act authorizes the disclosure of cell phone location data with a lesser showing than the probable cause requirement demanded by a search warrant.  Read the rest of this entry »

North Korea Developing EMP Bomb, Electronic Weapons

From ABC News:

The North is believed to be nearing completion of an electromagnetic pulse bomb that, if exploded 25 miles above ground would cause irreversible damage to electrical and electronic devices such as mobile phones, computers, radio and radar, experts say.

The current attempts to interfere with GPS transmissions are coming from atop a modified truck-mounted Russian device. Pyongyang reportedly imported the GPS jamming system from Russia in early 2000 and has since developed two kinds of a modified version.

FAA to pilots: Expect ‘unreliable or unavailable’ GPS signals

Unspecified Pentagon ‘tests’ cited

“The US Federal Aviation Administration is warning pilots to expect “unreliable or unavailable” signals from their global positioning gear as a result unspecified tests being carried out by the Department of Defense.

The Notice to Airmen, or NOTAM (PDF) said the GPS tests will be carried out beginning Thursday and are expected to last through February 22. They will cause spotty GPS signals in a several hundred mile radius centered off the coast of Florida.”
