GPS Units Disable Themselves If They Go Faster Than 1,200 MPH

Saturday, August 13th, 2011

This is somehow a legacy border, but anyone out there have busted this fact? – GPS units disable themselves if they go faster than 1,200 mph and if they go above 60,000 feet…

GPS module

In GPS technology, the phrasing “COCOM Limits” is also used to refer to a limit placed to GPS tracking devices that should disable tracking when the device realizes itself to be moving faster than 1,000 knots (1,900 km/h; 1,200 mph) at an altitude higher than 60,000 feet (18,000 m).This was intended to avoid the use of GPS in intercontinental ballistic missile-like applications.

Some manufacturers apply this limit literally (disable when both limits are reached), other manufacturers disable tracking when a single limit is reached.

This limit is a frequent obstacle encountered, if not discussed, among hobbyists seeking to make high altitude balloons and of course would be a problem for homemade space programs.

Japan setting out to get its own GPS off the ground

Sunday, July 3rd, 2011

japan-gps.jpgHow’s your Sunday? ah-ha, here some GPS-related article for your weekend technological feed, have a nice weekend.

The Japanese government – with the the assistance of private firms – is ramping up research on a Japanese version of the Global Positioning System in a bid to turn satellite-based technologies into a key export, the Nikkei reports. As far as we know,  it’s already runs. But turning it into an export – is really a good idea to me.

Plans are afoot to conduct joint research and development on this – nine firms and two organisations are slated to participate in a study group to be formed by the Ministry of Economy, Trade and Industry at the end of the month, with an aim to come up with new services in five years, the report says.

The venture will include companies such as NEC and Mitsubishi Electric Corp, which develop satellites or ground facilities, as well as those with a broad range of businesses, including transport systems, logistics and machinery.Having launched a quasi-zenith positioning satellite last September, the addition of two or three more satellites will enable an around-the-clock service, though specific plans for the second satellite haven’t been drawn up yet.

The Japanese satellite system is designed to supplement the GPS currently operated by the US, and is meant to cover the region, including that of Southeast Asia and Australia.A domestic GPS would yield many benefits beyond just making and launching satellites – with a projection that the overall market will grow from around four trillion yen in 2008 to roughly 10 trillion yen in 2013, a wide range of infrastructure-related fields will stand to grow as well.

Public bus transportation notifier

Friday, April 16th, 2010

bus-notifier.jpg

Knuckles904 at Random Hacks of Boredom was tired of waiting for the bus. His town had installed GPS units on the buses so that riders could track their locations via the Internet so he knew there should be a way to avoid the wait while also never missing the bus. He developed a sketch for an Arduino to check the bus location and notify him when it was on its way.

This method saves him from leaving his computer running. It parses the text data from the public transportation website and updates both an LED display, as well as a Twitter feed. Now he can monitor several different bus lines via the hardware at home, or though a cell phone if he’s on the go.

This guy have done a useful tricks and provides some sources to make this project works. Well done!

Open Source Lion-Tracking Collars In the Works

Thursday, April 15th, 2010

liongps.jpg

Want to help save some lions in Kenya? Well, help these guys make some open source lion-tracking collars, complete with GPS and GSM on board.

Lions are not doing too well in Kenya, with only 2,000 or so left. Two groups called Lion Guardians and Living with Lions are dedicated to studying and saving the diminished lion population. In order to help them out, Justin Downs of Brooklyn’s GRND Lab built them a solar-powered treehouse last year. Now, he’s working on some of the aforementioned collars to help them track the lions.

He’s looking for donations on Kickstarter for the project now, so if your passions create a Venn diagram between open-source hardware and lions, well, here you go.

Arduino balloon tracking

Friday, March 19th, 2010

The Ferret is a high-altitude balloon tracking hardware package. Created by [Adam Greig] and [Jon Sowman], it uses an Arduino to gather NMEA data from a GPS unit, format the data into a string, and transmit that string on narrow-band FM. The project, built in one afternoon, is a tribute to the prototyping simplicity the Arduino provides.

The unit was powered by four AA batteries, using the Arduino’s on board voltage regulator. This provided a bit of heat which helps in the frigid reaches of the upper atmosphere. The bundle above was put in a project box and attached to the outside of the balloon’s payload, then covered with foam for warmth and moisture resistance. This tracking is a lot less complicated than some of the photography setups we’ve seen for balloons. It’s also more versatile because it broadcasts the GPS data so that many people can track it, rather than just logging its location.

AIDA the dashboard bot

Sunday, November 1st, 2009


In an attempt to create more interaction with our vehicles, researchers have created AIDA. AIDA is basically a car computer and GPS that has some well designed personification. That cute little face will learn your daily habits and schedules and make recommendations to keep you out of traffic. We really like the idea, and the little bit we see of AIDA already has us falling in love, but won’t the placement be a distraction? We already know some people who give their car a name and treat it like a person, we don’t want to imagine what would happen if their car actually had some interactive personality. AIDA’s motion and emotive display are worthy of the crabfu challenge for sure, but do we want AIDA on our dashboard? Yes, most emphatically. She can sit right by the little hula girl.

Blue Force Tracking

Wednesday, October 21st, 2009

Tank_traning.jpg

 Blue Force Tracking is a United States military term used to denote a GPS-enabled system that provides military commanders and forces with location information about friendly (and despite its name, also about hostile) military forces.

In military symbology, the color blue is typically used to designate friendly forces while red is used for enemies, and green or yellow are used for neutral forces.

Blue Force Tracking systems consist of a computer, used to display location information, a satellite terminal and satellite antenna, used to transmit location and other military data, a Global Positioning System receiver (to determine its own position), command-and-control software (to send and receive orders, and many other battlefield support functions), and mapping software, usually in the form of a GIS, that plots the BFT device on a map. The system displays the location of the host vehicle on the computer’s terrain-map display, along with the locations of other platforms (friendly in blue, and enemy in red) in their respective locations. BFT can also be used to send and receive text and imagery messages, and Blue Force Tracking has a mechanism for reporting the locations of enemy forces and other battlefield conditions (for example, the location of mine fields, battlefield obstacles, bridges that are damaged, etc.). Users will include the United States Army, the United States Marines Corps, the United States Air Force and the United Kingdom. Recently, the United States Army, the United States Marines Corps have reached agreement to standardize on a shared system, to be called “Joint Battle Command Platform”, which will be derived from the Army’sFBCB2system that was used by the United States Army, the United States Marines Corps, and the Army of the United Kingdom during heavy combat operations in Iraq in 2003.

Brake assist with GPS data for new Nissan Fuga

Saturday, August 15th, 2009

nissan-fuga-system.jpg

Nissan has announced a new driving aid system called the Navigation-Cooperative Intelligent Pedal which basically uses data from the car’s satellite navigation system to help smoothen the drive when it comes to a curving road.

How many times have you approached a bend and then suddenly realised you’ve gone in too fast? Can you see ahead past a blind corner in a bend? Some bends can sharpen mid-way… and then you panic and have to deal with understeer or worse! If the system detects that you are about to do this, it sounds an audible warning.

If you persist, the system moves the accelerator pedal upwards to assist the driver to release it. Once the foot is lifted off, the system will smoothly reduce vehicle speed by braking. The system will debut on the new Nissan Fuga when it is unveiled in fall 2009. As it currently is, the Fuga is the Japanese name for the Infiniti M.

A similiar system was introduced earlier this year on the Toyota Crown Majesta, though it doesn’t work exactly the same. The Toyota system uses gear changes and engine braking to help slow the car down in anticipation of a corner (the car is aware of this via the in-car GPS system too) or a toll booth.

In addition to that, the Toyota system will activate a brake-assist function if it thinks the driver is too late in decelerating when approaching a stop sign or a junction.

Cobra Connex Stolen Vehicle Recovery system for the Honda Accord

Sunday, July 26th, 2009

Here’s more info on the Connex Stolen Vehicle Recovery system that is currently an option with the Accord.

The system is actually by the Cobra vehicle security company, and is pretty reknown. For example, the Italian company’s Connex systems are being used by alot of companies such as Audi France where they use Connex as the standard alarm and recovery solution for the Q7, A8, S, RS and V8-engined cars.

When you buy the package from Honda at RM3,660 inclusive of installation, first year annual service fee (RM360) and a compensation guarantee (optional and worth RM140), it will be installed at the Honda dealer. This package is currently for Peninsular Malaysia cars only, and comes with a 3 year warranty.

Cobra LogoNow what is the compensation guarantee? Basically if your car is recovered within 72 hours of theft management notification, you get cash of up to RM5,000 and bills of up to RM5,000. This covers bills for repair and replacement of damaged parts.

If the stolen vehicle is not recovered within 72 hours, you get a cash compensation of RM15,000 and a RM15,000 subsidy at Honda dealers for a new car if the car is not recovered at all. If recovered after 72 hours, you get a RM5,000 compensation for repair and replacement of parts related to the theft.

The system operates based on GPS to track the vehicle location and a GSM-based communication device that runs on the cellular networks to communicate with the Cobra Connex operation center. The annual fee of RM360 (first year free) covers the GSM device charges, you will not have to pay any extra cash to maintain the Connex system’s GSM SIM card.
