Solar flares set to wreak havoc on GPS signals

The sun's activity isn't usually a hot topic around these parts, but when it threatens to derail satellite navigation services around the world, it must surely take center stage. UK researchers have corroborated Cornell's 2006 warning that our solar system's main life-giver is about to wake up and head toward a new solar maximum -- a period of elevated surface activity and radiation.

It is precisely that radiation, which can be perceived in the form of solar flares, that worries people with respect to GPS signaling, as its effects on the Earth's ionosphere are likely to cause delays in data transmission from satellites to receivers and thereby result in triangulation errors. Still, it's more likely to be "troublesome than dangerous," but inaccuracies of around 10 meters and signal blackouts that could last for hours are being forecast in the absence of any intervening steps being taken. So yes, you now have another reason not to trust your GPS too much.

GPS for PSP finally goes on sale

gps We've rumored, ogled, and previewed, but it's time to get official, folks. The GPS Receiver for the PSP launches Thursday in Japan, for the low price of $60, at least according to Play-Asia.com.

No word on how much it'll cost you if you buy it direct from the source, although our previous post suggests a ¥5,000 ($43) price point. PSP News reports that it'll work nicely with a few titles, including "Minna no Golf-jou," "Metal Gear Solid: Portable Ops," "Planetarium Creator Ohira Takayuki Kanshuu: Home Star Portable," and "Navigation Soft." How did we ever navigate the world without this GPS antenna perched atop our PSP before?

Garmin® Introduces Forerunner 50

Garmin introduces Forerunner50 as only sports watch with automatic wireless sync. Forerunner 50 is an affordable, sleek and intelligent way to help runners and walkers track their workouts, automatically store their data and reach their personal fitness goals. The announcement strengthens Garmin’s role as an innovation leader in the fitness world and reinforces the company’s commitment to enriching its customers’ lives.

The principle: You simply call the telephone number of the GPS PRO Dog collar with your handy /mobile phone /cell phone. The GPS receiver of the collar, estimates the position of the dog and sends the coordinates immediately as SMS (Short Message service) over the Global System for Mobile Communication (GSM) directly on your mobile phone display. The accuracy of the positioning amounts to the average less than 15 meters.

The central element of the Forerunner 50 system is an advanced fitness watch which interfaces wirelessly with other fitness devices such as a heart rate monitor or a foot pod that monitors speed and distance. The system includes a wireless USB ANT™ Stick that plugs into the user’s PC and automatically downloads workout data stored on the watch to a personal computer. No cables are necessary as the Forerunner 50 synchronizes with the computer once it is in close proximity. Depending on the model purchased, the Forerunner 50 accurately monitors and records heart rate or speed and distance or all of the above. The workouts themselves are made easier with the Forerunner 50 as its heart rate monitor and foot pod activate automatically upon movement, removing the need to turn the lightweight accessories on and off.

With this entry-level fitness watch priced at under $100, Garmin broadens its appeal to the millions of consumers who want to burn calories in a cost-effective manner. While the Forerunner 50 processes much of the same data as its GPS-enabled predecessors, those functions are packaged in a very compact device the size of a typical fitness watch. The Forerunner 50 can track and record up to seven hours and 100 laps of detailed exercise data. And because the Forerunner 50 records its data from the heart rate monitor and foot pod, users can exercise indoors — for example, accurately monitoring their heart rate while on a treadmill or tracking how far they walk each day in the office. The foot pod enables the Forerunner 50 to track and record speed, distance, cadence, steps and calories burned. Cycling enthusiasts will enjoy the versatile options of adding a bike speed and cadence sensor and a handy bike mount
.

The Forerunner 50 will be sold in a few different combinations, some with the foot pod, some with a heart rate monitor, and all will come with a wireless USB stick so that information can be downloaded wirelessly from the watch to the USB stick and then into your computer.
