NavSpark: Arduino Compatible with GPS GNSS Receiver

The iPhone’s Positioning Sensors Were Never Good. Much is being made of Gizmodo’s tests showing that the positioning sensors in the iPhone 5s are off.

The iPhone’s Positioning Sensors Were Never Good

Not just a little off, but off in a non-trivial way. The gyroscope read 3 degrees off, the compass 8 to 10 degrees off, and even the accelerometer seemed to be inaccurate. There was only one problem with Gizmodo’s experiment: they only compared the iPhone 5s against the previous iPhone 5. That may have seemed reasonable at the time, but it assumes that the iPhone 5’s positioning sensors were accurate. Testing by TechHive in a variety of locations with an iPhone 4S, 5, 5c, and 5s now shows that the iPhone’s positioning sensors have never been any good. The Shine: A Self-Tracking Device That You'd Wear Even If It Didn't Do Anything. If you wear a self-tracking fitness device like the Fitbit, Nike FuelBand, or Jawbone Up, you probably do it because you’re keeping tabs on your health goals.

The Shine: A Self-Tracking Device That You'd Wear Even If It Didn't Do Anything

Unless you’re trying to show off your membership in the self-tracking community, these devices just aren’t pretty enough to wear without a good reason--you’d never buy one simply as an accessory. Sonny Vu, the founder of Misfit Wearables, is aiming to give people self-tracking devices so unobtrusive and attractive that they’ll want to wear them all the time. "Don’t you want a product that you’d wear even if it didn’t measure anything? I tried wearing a Fitbit on a tie once and it tore the silk on the tie," says Vu, who also acknowledges that he’s still a fan of the device. "We should expect more from wearable technology. Misfit is gunning for simplicity with the Shine, which measures steps, swimming strokes, and pedal movement on bikes.

"We decided, do people really want to know how many steps they took? Untitled. The future of GPS Chips: Sony to launch low powered GPS chips aided by motion sensors. Home » Gadgets » The future of GPS Chips: Sony to launch low powered GPS chipset aided by motion sensors Any smartphone user who has used GPS for navigation or location based services would know how much of a “Battery Hog” GPS on the phones can be. They drain your battery at an exponential rate. SONY – low powered GPS Chipsets Thankfully, Sony was paying attention to it and all this will end soon.

Arduino GPS Shield: Computers & Accessories. Geo Data Logger: Arduino+GPS+SD+Accelerometer to log, time-stamp, and geo-tag sensor data. UPDATES Oct 17, 2013: I have published a guide on using your Android phone to accomplish a similar task by leveraging your Android device's built in GPS and sensors.

Geo Data Logger: Arduino+GPS+SD+Accelerometer to log, time-stamp, and geo-tag sensor data

Feb 6, 2013: Featured on GeoAwesomeness Nov 24, 2012: Featured on Hackaday Nov 21, 2012: Featured by John Boxall @ Freetronics Nov 20, 2012: Featured on Dangerous Prototypes INTRODUCTION I thought it would be educational to build a prototype that I can take on the road to log, geo-tag, and time-stamp sensor data to be analyzed later with mapping and/or data analysis applications.

So I figured why not start with a gadget that can log road conditions. This prototype, the Bump-O-Meter, measures road conditions by using an Arduino, a GPS receiver, an SD card, and an accelerometer sensor. This prototype is a generic sensor logging/geo-tagging gadget which means the accelerometer can be replaced with any other sensor(s) to log and map anything anywhere.

This guide is divided into the following sections: Arduino GPS shield. Overview It's based on u-blox NEO-6M GPS module , and the footprints is compatible with Arduino/MEGA boards.

Arduino GPS shield

The regular GPS pins (RX, TX) can be connected to D0-D7 of Arduino. Adding GPS to your Arduino has never been easier. Multiple GPS receivers attach easily to the shield, and with the example sketch (check below), you will be able to locate your exact position within a few meters. Here's where we are.

GPS Shield With SD Card Slot for Arduino V2. Adafruit Ultimate GPS. This is not available in v1 or v2 so if you do not see the uFL connector, you have an older version of the module which cannot support antennas All Ultimate GPS modules have a built in patch antenna - this antenna provides -165 dBm sensitivity and is perfect for many projects.

However, if you want to place your project in a box, it might not be possible to have the antenna pointing up, or it might be in a metal shield, or you may need more sensitivity. In these cases, you may want to use an external active antenna. Active antennas draw current, so they do provide more gain but at a power cost. Check the antenna datasheet for exactly how much current they draw - its usually around 10-20mA. Most GPS antennas use SMA connectors, which are popular and easy to use. The Ultimate GPS will automagically detect an external active antenna is attached and 'switch over' - you do not need to send any commands There is an output sentence that will tell you the status of the antenna.

GPS SD Shield for Arduino. GPS Receiver (MTK3339) .:oomlout:. Looking to add location awareness to your next project this is the perfect solution.

GPS Receiver (MTK3339) .:oomlout:.

This is a really high quality GPS receiver (10 Hz, 66 Channels & high sensitivity) mounted on a really friendly breakout board (3-5v logic compliant, on board regulator & mounting holes) all for a very reasonable price. Using it is super simple as well, just four wires, then either get it up and running with an example sketch (link below) or the easy to use parsing library (link below) to start.
