Canmore GT-730F USB GPS Stick Dongle (WAAS - A-GPS - 54 channels)

The Canmore GT-730F USB GPS Stick Dongle is an USB GPS Dongle that is easy to use, compact and provides excellent GPS performance. Key features: Excellent GPS performance without the need to use an USB Extension Cable Majority of the USB GPS dongles in the market require an USB extension cable to be used to extend the GPS antenna away from the laptop or a GPS position fix may not be obtained or takes forever to obtain a position fix. This is due to the fact that notebook / laptop produces electrical interference that weakens the GPS signal in the nearby vicinity. The Canmore USB GPS Stick Dongle is an exception; thanks to the enhanced antenna and RF frequency tuning implemented in the Canmore USB GPS Stick Dongle, it could obtain GPS position fix without the need of an USB extension cable. Supports A-GPS (aka Assisted GPS), which shorten GPS position fix time to 15 seconds from 30 seconds With the supplied A-GPS software (PC application), users may download the most updated satellite data (known as almanac) from SkyTraq servers and store the satellite data in to the Canmore USB GPS stick dongle. Rubberize coating on the top surface of the USB GPS dongle for easy removal. Canmore GT-730F USB GPS Stick Dongle has 54 parallel channels and its Venus 5 search bins provide short start-up time and fast signal acquisition. Having fast time-to-first-fix and high sensitivity, the GT-730F offers good navigation performance even in urban canyons. Satellite-based augmentation systems, such as WAAS and EGNOS, are supported to yield improved accuracy. Software compatibility: The Canmore USB GPS Stick is compatible with nearly any GPS mapping software available and fully compatible with NMEA standards (all versions). Hardware compatibility: Works with UMPC / Laptop / Notebook / Tablet PC with a USB port. Included USB Drivers: Windows XP, Vista 32-bit/64-bit.

User Reviews about Canmore GT-730F USB GPS Stick Dongle (WAAS - A-GPS - 54 channels)

This is a very useful device. I've tried several gps modules to install inside the laptop including Holux gpsslim 240, Bluetooth, usb, etc. (I didn't want any external hardware to carry around) this is the only gps worked inside the computer (under and very close to touchpad#. The vista drivers can be used for Windows 7 32bit, the inital #out-of-the-box) start-up and satelite acquisition takes about 90 seconds (i guess to load the ephemeris and other satelite predicted locations# . The next day consecutive cold start-up takes between 30-60 seconds. Hot startup is about 14 seconds. The A-GPS #assisted gps) option is not very effective I tried both the GPS Viewer software (auto A-GPS configuration) and also Skytraq AGPS tool. Both tools download the gps sat ephemeris data and flash it to the unit succesfuly but I couldn't see any speed improvement. (Note use the unit with 38600 baud rate otherwise NMEA data seems corrupted) -- Useful device
I've read several reviews of this item.

I believe I'm a tech savvy person, so I hope I can make this clear. I'm going to start with the device itself:

It's a GPS receiver, don't expect anything else from it. If you're expecting more, you're wrong. The device will connect to your USB port and act as a "serial" device, that you can read from. That is, like a terminal that prints information in the standard NMEA format.

That being said, the driver provided for Windows, it's simply a driver that allows you to use a USB port as a serial port. Therefore, You'll be able to connect to the device using something as simple as Hyperterminal (If you still use Windows XP). - Note aside: For people that feel they understand about computers: this driver simply makes your USB port look like a COM port.

Since reading from a serial device is not an issue for Linux (and I'm assuming, although I haven't tried, for Macs which are Darwin/Linux based), you just need to make sure that the port speed is set to 38400. Otherwise, you'll only get gibberish (data that doesn't mean anything). I found that in Linux, you can do that with the command "stty". How? You plug your device, and check what USB port it's connected to. Which should show up as /dev/ttyUSBx, where x is a number starting from zero. Then run a command along the lines of: 'stty 38400 -f /dev/ttyUSBx'. And then read from it (using for example, cat): 'cat /dev/ttyUSBx'.

Boom! All the standard NMEA lines should show up. (Just the same if you use hyperterminal, and configure the right COM port to that speed. I thought Macs would do that transparently, but apparently it doesn't)

PROS: It's really easy to install anywhere, once you know how the device is supposed to work. It's pretty accurate with the coordinates, once it acquires the signal.

CONS: I've found that when you get into a tunnel (of course it won't work), but after that, it seems to take longer to re-acquire the signal. It's not the fastest GPS, but it's cheap and does the job.

On the other hand, seems important to remark that several versions of MS Streets and Trips / MS Map Point DO NOT support the serial speed 38400, but only 4800. Therefore, they won't work with this device.

Last, but not least, I've found very interesting information and pages with applications, particularly, if you don't want to learn the NMEA standard, yet play with the device, you can capture chunks of data and use it at [..] -- It does what it's supposed to do.
