A while back I was awed and wrote about what I thought was a miniscule GPS receiver that fit on a keychain. Well, I just received a smaller one from Proporta.com that is even more awesome.
The Freedom Keychain GPS 2000 comes in black with a rubberized coating, weighs 0.77 ounces, and measures 1.81 x 1.26 x 0.58 inches with a swivel detachable hook on one end. On one side is a slider power switch and a mini-USB port for charging.
In the box, you get a power charger for your car and a USB cable for charging from a computer. There is also a small printed user’s manual with instructions offered in ten languages.
Some of the important technical data are as follows:
• Bluetooth v 2.0
• 10 meter range
• MTK chipset
• 51 channels “all-in-view” tracking
• ARM7EJ-S processor
• Protocol: NMEA 0183/ V3.01, GGA, GSA, GSV, RMC
• Baud rate 115,200
• Frequency L1, 1,575.42 Mhz
• Tracking Sensitivity 158dBM
• WAAS/EGNOS/MSAS enabled
• P:osition deviation: 10 meters 90% 2D RMS 1-5 meters
• Velocity: 0.1 m/sec
• Cold/warm/hot start: 36/33/1 sec
• Rechargeable 350 mAh Lithium polymer battery
Operation is simple and straight forward. After charging the device, switch the power on and pair it with your GPS navigation device via Bluetooth using the normal procedure.
On the end opposite the keyring hole are a series of LED lights that glow blue for Bluetooth connection, orange for GPS, red for battery, and green for charging.
Once you are paired with a navigation device, you are good to go. This miniscule signal grabber is a powerful little fellow. You don’t even have to have it in plain view of the satellites in your windshield. You can keep it hooked to your ignition key while navigating, and it will receive the signal just fine. You can also put it in your pocket, backpack or purse.
