Part 2 Features
G-RAYS 2 is the Bluetooth GPS receiver with internal antenna. ublox used in its core is high-tech component and included
function of auto-log record of journey, which are useful in
navigation, security tracking purpose, topography and other
agricultural needs. USB connector and Bluetooth interface
ensures easy linking with other electronic devices .The GPS
acquisition status, the last record of time and position can all be
stored in non-volatile memory. It has 16 GPS channels and its low
power-consumption can last continuous 10 hours of operation. GRAYS 2 can boast of its smallest size ever with fullest features in
the world.
G-RAYS 2 contains u-blox GPS IC and the high-performance
CPU.
Maximum 16 channels can be acquisitioned quickly.
Highest tracking sensitivity: -158 dBm
Internal decode ”SBAS” is used excluding the need for
external hardware in receiving SBAS signal.
System supports NMEA0183 2.3 (GPRMC, GPGGA, GPGSA,
GPGSV) for data transfer.
Data-logging acts like the in-flight black box and can record of
position, date and time as long as power source is maintained.
For down-load of log-data and programming of G-RAYS 2,
provided software tool “Time Machine X” can simplify usage.
It is designed to be water-proof.
Data link can be done thru Bluetooth within 10 meter range.
Versatile design aimed for car/personal navigation, fleet
management, AVL, tracking and topography purpose.

Part 3 Safety notes
GPS (Global Positioning System) is provided by the United
States government. Its accuracy may varies depending on
speci al conditions (area at war or if it is blocked) . Any control
by USA will affect this system and its accuracy.
If installed on the transportation device, driver must not
operate this while driving.
GPS performance is affected when satellite coverage is
degraded as near a high-rise building, in the tunnel or under a
cover.
Personal replacement of components and re-structuring of
this is prohibited and may result in loss of legal usage.
Operation of this device is strictly prohibited in highly
explosive environment such mining, in-flight or other
unauthorized area against use of this.
Avoid exposing this at places of high temperature and
humidity.
Return to original dealer immediately if it emits strange smell
or fume.

Part 4 Quick user’s guide
Package: G-RAYS 2 (Bluetooth GPS with logger)+USB
cable+ sticker＋car cigarette lighter adapter + power adapter ,
installation Disk, Quick user’s guide.
G-RAYS 2 Operation:
Temporarily press power button to power on it. The
Bluetooth and GPS status LED will glow to confirm it is in
GPS mode and GPS start acquisition.
GPS LED glows red to show GPS acquisition is done (1
Hz). But if this LED is solid on, the GPS acquisition fails.
Temporarily press on power button. Bluetooth will turn off
after Bluetooth LED goes off. Another press on power
button can turn Bluetooth on after its LED glows again.
After power on, press and hold power button to turn the
power off.
If Power LED (glows red) starts to blink, the power is low
and needs recharging. Power LED stays solid while
charging .It snuff out red LED and glows green LED solid
on after it is fully charged.
Temporarily press “TRACK” button (GPS LED flash green
light) to mark point in current track when log function is
enable.
Press and hold “TRACK” button (GPS LED glows green
and snuff out after 1.5 sec) to re-start new track when log
function is enable.
When the USB is used as interface:
USB driver must be installed first.
After connection to USB port of computer, place the G-
RAYS 2 at suitable area where it can best receive GPS
signal for acquisitioning.
6
Power it (or switch its power on).
G-RAYS 2 will start acquisition.
When the Bluetooth is used as interface:
Ahead of Bluetooth connection, make sure the target
device to pair can support Bluetooth SPP master.
After pairing with G-RAYS 2, place it at suitable area where
it can best receive GPS signal for acquisitioning.
Activate the application software of paired device. G-RAYS
2 starts to provide GPS data.
Battery charging:
Connect G-RAYS 2 with USB cable and turn on power
source.
Charging can be done by USB cable connected to
computer r, power adapter or car cigarette lighter adapter.
Charging is in process even during G-ray is operating.

Part 5 Operation notes
G-RAYS 2 will do self-check once it is powered. Bluetooth
and GPS start to work when both Bluetooth LED (glows blue)
and GPS LED (glows red) turns on. GPS automatically starts
acquisition and auto-logs. If sky is clear overhead, it requires
only 34 sec for acquisition. (If the data in its memory is still
valid, it needs only 4~33 sec). After acquisition, G-RAYS 2
starts output data of position, speed and time in NMEA0183
format.
For the first time if it is placed at the area well exposed to the
satellite signal, this device requires approx 13 min
(theoretically 12.5 min) to receive or update Almanac. Refer to
trouble shooting guide when signal is not received well.
If G-RAYS 2 formatting the internal data is not correct, or if
satellite data has been deleted, it takes longer time to position.
But under the following conditions, it can take even longer
time to get cold start.
If it is not in use for over 3 months (the almanac is old-
dated).
If the last recorded position data is over 500 km.
After positioning, G-RAYS 2 transfers navigation data thru
export interface as below:
Latitude
Longitude
Altitude
Speed
Date
Time(UTC time)
Estimated error
Satellite status

Receiving status
After positioning, if auto-log function is activated, G-RAYS 2
begins to auto-log the following way.
Maximum data up to 131072 Points.
Recording in a circular way.
Auto-logging goes on without the need of any device.
Log-data can be read out by way of the ”Time Machine X”
software included.
Data can be read out thru USB or Bluetooth.
Data includes latitude, longitude, altitude and time in year-
month-date-hour-min-sec.
After successful positioning, it wills auto-log GPS data into
its internal memory chip. It recorded in a rotational order.
The earliest (oldest) data will replaced by the latest (newest)
one when memory space is full (when data excesses
131072 maximum).
Auto-log will continue even the Bluetooth is switched off.
When auto-log function is disabling and the Bluetooth is
switched off, its power will be turned off after 10 minutes
(that interval can be set by yourself). It will not shut down
while auto-log function is activated.
