GPS satellites tell us where we are, but what tells them where they are?

By Jeff Salton

Global Positioning System (GPS) devices have permeated society to the point where millions of us rely on them daily for directions, locations and traffic avoidance (if only they could tell me where I left my car keys). GPS satellites send signals to a receiver in your handheld or car-based GPS navigator, which calculates your position on the planet based on the location of the satellites and your distance from them. The distance is determined by how long it took the signals from various satellites to reach your receiver. But have you ever thought what tells the GPS satellites where they are in the first place?

Google announces free turn-by-turn maps app for Android - looks the goods

By Darren Quick

01:37 October 29, 2009 PDT

Every platform needs a killer app and for the Android OS the early contender for that title has to be the just announced Google Maps Navigation for mobile. Only available for Android 2.0 phones, the new application takes the current Google Maps for mobile and gives it a hefty shot of steroids. Most of the new features that set the app apart from most in-car turn-by-turn navigation systems come courtesy of its Internet connectivity, which makes it possible to access a wealth of relevant information residing on Google’s servers while out and about.

EU launches free EGNOS satnav system

By Darren Quick

20:49 October 5, 2009 PDT

The European Commission has announced the official start of operations of the European Geostationary Navigation Overlay Service (EGNOS), a satellite based augmentation system (SBAS) that improves the accuracy of the current US Global Positioning System (GPS) and Russian GLONASS system signals from about ten meters to two meters. Like the U.S. GPS, the EGNOS Open Service is accessible free of charge to any user equipped with a GPS/SBAS compatible receiver within the EGNOS coverage area, which includes most European states and has the built-in capability to be extended to other regions, such as North Africa and EU neighboring countries. Most receivers sold today in Europe meet that requirement. Read More

TXTBlocker lets parents and employers disable texting while driving

By Paul Lester

01:58 October 3, 2009 PDT

It should come as no surprise to hear that texting while driving is a particularly dangerous thing to do. Recent studies have shown that drivers are 23 times more likely to get into an accident if they are texting and an astonishing 46% of teens have admitted occurrences of driving while distracted as a result of fiddling with phones.

A new product called TXTBlocker addresses these issues directly by disabling a number of phone functions, with the specific impact decided by a choice of settings available from an account page online once you subscribe. Read More

BEAR-4: The first amateur HD video in (near) space

By Paul Ridden

19:30 September 30, 2009 PDT

After receiving an email from a Japanese enthusiast, a group of amateur radio high altitude balloon buffs jumped at the chance to help record the first ever non-professional near space high definition video, and maybe set a new altitude record on the way. After squeezing the HD camcorder and tracking hardware into a styrofoam box, and a couple of false starts, the 1500g high altitude, hydrogen-filled balloon was away. Read More

SurroundSense uses your phone's sensors to figure out where you are

By Dario Borghino

17:02 September 30, 2009 PDT

Smartphones use GPS locating for a variety of functions but mainly they're used on the road where their accuracy - only within 10m - is basically a case of 'near enough is good enough'. But try using one indoors. They don't work! Nor can they distinguish between two adjacent environments, however different. And 10m can make a big difference inside a shopping complex or multi-roomed office block. In a research jointly sponsored by Microsoft, Nokia, Verizon and the National Science Foundation, a group of computer engineers from Duke University is working on achieving better indoor localization using a combination of sounds, lighting and accelerometer data picked up by a mobile phone. They hope it will supplement the use of GPS systems, which most users know, have their limitations. Read More

It wasn’t so long ago that most of us relied on the humble road map to get us from A to B, but with the advent of GPS navigation systems, our map-reading skills are rarely required. There is no denying the usefulness of GPS systems, particularly if you have a tendency to get lost, but do they actually save you time? According to a recent proprietary research study, if you have a traffic-enabled GPS and spend most of your time on busy roads, you could save yourself up to four days a year. Read More

What’s worse than having to watch Aunt May’s and Uncle Stan’s ridiculously long digital ‘slide show’ of their recent European vacation? Listening to them argue over where each photo was taken, and what it is. If they’d had a JOBO photoGPS attached to their camera's hot-shoe, your saga would be over in six hours, not 16! The JOBO photoGPS fits most cameras and captures the geo-data of each photo's location. This allows photographers to know the location of each shot and automatically search, sort and organize their pictures according to country, city, street using the Organizer software that comes with the unit.

By Jeff Salton

19:15 August 18, 2009 PDT

If you’ve ever owned a recalcitrant retriever, a cat-crazy collie or an overly playful poodle, you’ll know the anxiety of watching them run out of view in search of new adventures, oblivious to your shouts of anguish (and anger). A GPS-enabled collar could be handy for tracking down wayward canines and keep them out of harm’s way … or the clutches of dog-nappers or an over-zealous ranger lurking in the neighborhood. The RoamEO is the latest GPS device for owners who worry about their dogs’ disappearing acts or who are sick of spending valuable time searching for that ‘duck-hunter’ who’s too dog-tired to return with the catch.

PedalPower+ charges cyclists' phones, GPS, iPods

By Jeff Salton

21:52 August 9, 2009 PDT

In bygone days, a bicycle dynamo struggled to generate enough energy to power a weak headlight for the lonely cyclist riding home on a dark night. Back then it was the only electronic application that a cyclist needed because dynamos were first invented when riders still made calls from public telephone booths or stopped to read a map for directions. But a new bicycle dynamo system called PedalPower+ can help recharge the arsenal of battery-powered accessories modern cyclists’ rely on for communications, navigation and entertainment - on the fly.

A new vehicle billed as the most technologically advanced police car in the world is due to begin testing in the US. Based on the Australian-built Holden Commodore, which were rebadged as Pontiac G8s in the US, the car aims to turn a standard vehicle into a ‘virtual office’ for emergency services personnel. It replaces the cluttered, cockpit-style gadgets that abound in current police cars with a large single touchscreen display embedded in the passenger dash and throws in some Bond style crime fighting gear like an air gun that fires a laser guided GPS tracking device onto fleeing vehicles.
