Login | Register | Cart Products GPS Receiver/ Data Logger Mouse Type GPS Receiver GR-213 U Smart GPS Receiver is a total solution GPS receiver, designed based on Si RF Star III Architecture. This positioning application meets strict needs such as car navigation, mapping, surveying, security, agriculture and so on. Only clear view of sky and certain power supply are necessary to the unit. It communicates with other electronic utilities via compatible dual-channel through USB interface and saves critical satellite data by built–in backup memory. With low power consumption, the GR-213 U tracks up to 20 satellites at a time, re-acquires satellite signals in 100 ms and updates position data every second. Trickle- Power allows the unit operates a fraction of the time and Push-to- Fix permits user to have a quick position fix even though the receiver usually stays off. Si RFstar III chipset with embedded ARM7 TDMI CPU available for customized applications in firmware High performance receiver tracks up to 20 satellites while providing first fast fix and low powe consumption. Compact design ideal for applications with minimal space. A rechargeable battery sustains internal clock and memory. The battery is recharged during normal operation. Users can adjust power-saving percentage (20%~80% which achieves the best power efficiency. User initialization is not required. LED display status: The LED provides users visible positioning status. LED “ ON” when power connected and “ BLINKING” when GR-213 U got positioned. Water proof design for industry standard.
If none of these FAQs seems to address your problem, look at the Upstream Bugs page. How can I verify operation of a new GPS? 1. First, check that the GPS has power. If it is a USB device, it needs to be cabled to a USB port to have power. All Bluetooth GPSes and some serial GPSes are powered by an on-board battery; check that the battery is present and charged. The GPS may have an on-off switch which needs to be in the 'on' position. 2. Most GPSes have a power-on LED; it should be continuously on or blinking once a second. If it is continuously off, your GPS is dead or disconnected. Check that it has power. 3. For anything other than a serial ( RS232) device, there should be a discovery utility that allows you to check that the device is connected. 3a. For a USB device, run lsusb before and after connecting your GPS; after, you should see an additional line indicating a new device. Expect the new line to describe a serial-to- USB adapter chip, often (but not always) the Prolific Technology PL2303. Then run dmesg, looking for a message indicating a new USB device of that kind and giving you the device path - /dev/tty USBn for some number n. 3b. If your receiver lists in lsusb(1) but doesn't show up as a tty USBx device, don't lose hope. It might be a tty ACM device, probably /dev/tty ACM0; some receivers, including for example the u-blox EVK 6 H evaluation kit, announce themselves as USB modems. 3c. For a Bluetooth device, see our Bluetooth instructions. 4. If you have installed a GPSD binary package on a Linux system and are using a USB GPS, you should not need to start gpsd manually, because the hotplug system will have done it for you. You should be able to start a test client (such as cgps or xgps) and watch it report fixes. 5. If your test client fails to run, a good test to try is to, after stopping any instances of gpsd that are running (eg, killall gpsd run.
