The new ground-based tech can pinpoint locations outdoors and indoors

While GPS struggles to find your exact location at times, a new positioning technology could step up and give a more accurate area both indoors and outdoors.

The new positioning technology is by Locata, and it uses ground-based equipment instead of satellites to send a radio signal over a certain area. This signal is reportedly a million times stronger than a GPS signal.

While GPS mainly gives outdoor locations, Locata's ground tech is tackling indoor locations such as huge shopping malls as well. Its receivers can be small enough to fit inside a cell phone, so if shoppers are lost in a large mall, they can use Locata on their smartphone to find a certain area.

When tested at the White Sands Missile Range in New Mexico, Locata worked to within 18 centimeters along any axis. GPS typically has location resolutions of a few meters. Locata's technology could bring the resolution as far down as 5 centimeters in the future, making location pinpoints even more precise.

Locata's signal is much stronger because solid objects like GPS signals don’t block it as easily. However, Locata could still use some help in urban settings with many buildings packed so closely together.

It is suggested that Locata's tech will not replace GPS, but rather, work with it to offer both satellite locations and ground-based locations for greater accuracy in different situations. For example, the Jigsaw Positioning System uses both Locata and GPS to guide the placement of drill rigs in Western Australia.

If you're lost in a shopping mall, how is 5cm accuracy any better than 18cm? A location difference of 13cm - about the length of a ball point pen - is not going to add any value.

Why does being lost in a shopping mall have to be the only reason to increase precision? What about applications for self driving cars? Do you want it to be able to measure within 5cm when your car is driving you through a crowded city, or 18cm?

While your point is valid, there will likely have to be a much larger margin of error than 18 cm for cars. For example, you will follow the car in front of you at a distance of 3 meters, where the extra 13cm of precision is very negligible.

Cars need to park.

Keys get lost and need to be found, it'ld be nice if they would report their location (instead of homing beacons).

How about automated logistics like Amazon? Forklifts could benefit from 5cm accuracy.

As I understood the guy's comments on the White Sands Missile range test, they had air craft traveling at 500 mph with 6 cm of accuracy at 30 miles range from the Locata beacon.
You forget that it isn't just the space in front of a vehicle that is important, the space on each side is important as well. It won't be long before we have autonomous vehicles on the road, and some of these will be things like large trucks. Would you rather have one driving past your parked car with 6 cm accuracy or 1 meter accuracy?
Other applications will be things like warehousing, supermarket stock, phone company equipment, and courier firms, where people can need to know exactly where an item is, especially when every item looks the same but isn't.

Spot on. I highlighted the White Sands performance here because that's what the New Scientist article was mainly about. However, if you care to look, you'll see there are already operational Locata systems in open-cut mines where we are providing better than 1.5cm (that's about 3/4 inch) across a 5km (3 mile) diameter area. Very soon we're introducing indoor warehousing systems that are delivering better than 2.5cm (1 inch) in brutal indoor radio multipath conditions where GPS is not available at all. Most folks don't seem to understand why you need this sort of accuracy, but ask anyone involved in automation or positioning machines, and they'll tell you it's absolutely essential if you want to have a useable autonomous system.

Have they never heard of Augmented GPS? Do people really think planes on autoland approaches are relying on +/-10 meters of accuracy? If you really, really need insane accuracy you can get down to millimeters using specialized GPS equipment.

Hi, MozeeToby. Yes, we have heard of augmented GPS, D-GPS, RTK and everything else that's GPS. In fact our company hires dozens of expert engineers in the field, and so do the USAF. In fact: our contract was awarded by the 746 Test Squadron, who happen to be The GPS Centre of Excellence for the US Military Tri-services , (http://www.holloman.af.mil/library/factsheets/fact... so I can assure your they are the best of the best. So ask yourself why THEY are almost the first to actively take up Locata technology as we exit stealth mode??

Look, I'm not having a shot at you in any way. I fully appreciate the power of GPS as a foundational technology, but I'm also acutely aware of its limitations... and YOU and many others would do well to become aware of the critical dependencies the world has now built around this extremely vulnerable technology. If you have any real interest in learning the truth (which the GPS industry has been trying to bury for some time now) you need to watch at least the first two video presentations (me and then Chris Morin, the technical director head of the 746 Test Squadron) from the Spatial@Gov Conference last month. They are here: http://www.locatacorp.com/2012/12/locata-at-cebit-...

DON'T SHOOT THE MESSENGER. The message in those videos is real and verifiable, and the GPS industry knows it. I'm just the guy, a year before 911, suggesting it may be a good idea to reinforce cockpit cabin doors. Locata is the company that's had to spend 17 years, 98 patents and sold the farm to produce a "fix" for the mess we're creating with GPS. One day you'll be very very glad we did. Have a great day.

Please, just stop right there.
I'll knock down your statements one-by-one. Your technology is very useful, but your statements here make no sense.
1. The Military will spend as much money as they get their hands on. This could be useful for tracking suspects (better ankle-bracelets anyone? Rather than finding their house, find which room they are in?)
2. CONSUMER GPS is vulnerable because it's unencrypted. Stop spreading FUD, kindly. The government has encrypted GPS technology that 1- Is more accurate 2-Is ENCRYPTED.
http://www.gps.gov/systems/gps/performance/accurac...
is the government's site on it. They use this page as a propaganda outlet, stating it's the same accuracy, but then uncovering the truth that government GPS is more accurate because the signal is encrypted and contains more information per packet.
3. You are NOT the "guy, a year before 911, suggesting it may be a good idea to reinforce cockpit cabin doors." for a number of reasons.
A - 9-11 was a tragedy, and I recommend that you stop using it to advertise your company. I lost loved ones in 9-11, as did thousands of others, and it's uncouth to use it to relate your company to something.
B- The aircraft industry and government have access to a better GPS signal with more satellites orbiting the earth (You see, GPS works on the "time lag" from satellites in orbit broadcasting the same time, GPS triangulates [or more] itself based on the lag, you're further away from a satellite if the time is older, hence, lag) than civilians do.

Like I said- your company's tech is good, but it's not a security thing, that's just FUD FUD FUD.

By the way - I AM SHOOTING THE MESSENGER - because the messenger is WRONG.

Dear dnyank1.
I'm sorry for your loss, and I share your pain. If you care to look you'll find I lost family in NY in 911 too... and it will always hurt.

With respect, we do NOT spread FUD, but tell the unadulterated truth. Please take the time to either watch the video referenced elsewhere here, or do your own research within GPS industry publications. EVERY reference I made in the video is from someone that is a respected, independent authority. I just collated and presented the information, starting with the US Government's own Volpe Report of 2001 and ending with UK's Royal Academy of Engineers Report from 2011 (http://www.raeng.org.uk/news/publications/list/rep... There are dozens of other authoritative reports if you do the research. Alternatively, just browse the front covers of GPS World Magazine over the past few years (http://www.gpsworld.com/archives/) and see how many articles highlight the massive jamming and spoofing problems now faced by GPS-type systems. If this is FUD, then most of the professional industry is responsible. As I said, I'm just a messenger for the information the industry has been trying to report for YEARS.

Your other points:
(1) The truth today is the military are trying to save money wherever they can, so there is no largesse here. Our technology is important because warfighters operate in an environment where the enemy is nowadays EASILY jamming GPS signals in operational areas, and they need something else for development purposes that works when GPS is jammed (which is VERY often).
(2) Locata can be encrypted , which gives you another reason why it's valuable. Civilian GPS is not encrypted, and to change that will take many years of effort, completely new satellites, and leave a huge number of current GPS devices inoperable or needing upgrades. That would be great for the GPS industry, but presents a nightmare for handling encryption keys for civilian use. Just check out what the military have to do for their encryption keys and you'll see how difficult it would be for general use.

Finally, some inaccuracies in your understanding (sorry) of GPS technology:
- Military GPS is NOT more accurate because it is encrypted. It's secure because of that. The military signal at L2 is more accurate than the civilian signal because their CDMA code is chipped at 10Mhz instead of the 1MHz civilian chipping rate. This gives the military system a higher code resolution of ~15 meters vs the ~30 meters in civilian code solutions.
- I think I've addressed #3, #3A above, but as for B... (i) the aviation industry uses exactly the same signals as the civilians do; (ii) The FAA is strongly working towards APNT (Alternate Position, Navigation and Time) because, like the military, they know they have SERIOUS problems emerging with GPS jamming. Please read a recent important article on the problem from the April 2012 issue of GPS World Magazine (http://www.gpsworld.com/archives/) and (iii) mate... with your apparent level of GPS technical knowledge I would honestly avoid trying to explain GPS time to the co-founder and CEO of a company that has 98 granted patents on synchronization technology and daily runs wide-area Locata networks that synchronize to better than a billionth of a second without using atomic clocks. And which is technology the GPS industry is adopting all over the place. Just sayin'...

The most important point in any of this is there is no FUD. Just facts. And even if I wasn't here, the authorities quoted above would not have gone away. Go read the info from someone that is NOT me. You can't shoot all of them.
