INTRODUCTION
Thank you for purchasing di-GPS® ECO ProFessional GPS receiver (digital images GPS).
di-GPS® ECO ProFessional GPS receiver (thereafter “ECO PF1 GPS”) is specially designed for a DSLR
(Digital Single-lens Reflex) camera. It provides real time position (latitude, longitude, elevation) and
the precise time (UTC time) information to your DSLR camera. It records the locations to each digital
image file so that you will never forget the exact location where you took the pictures.
ECO PF1 GPS has built with the latest third generation MTK MT3339 ultra low power consumption
GPS engine. It supports up to 66 channels of satellite searching with -165dBm sensitivity. ECO PF1
GPS repeats the last fixed position when no GPS signal is available or the unit is out of GPS coverage
with real UTC date/time.
ECO PF1 GPS allows you to save your present location data to your digital image file. Its State-Of-The-
Art technology provides extremely fast TTFF (Time-To-First-Fix), unrivaled high sensitivity and
superior performance in virtually any outdoor environment. ECO PF1 GPS receiver can work in a
place where GPS was not possible before : in the woods, under very heavy foliage, canyons, terrain
obstructions, in cities with densely populated high-rise buildings and even inside a train or a car, with
no external antenna required. It is designed to meet the rigorous demands of today's digital
photographers.

POWER SUPPLY
ECO PF1 GPS is not equipped with battery and On/Off switch. Power is supplied from the camera’s
battery via 10 pin connector.
The power On/Off is controlled by the camera, the GPS turn on when the camera’s metering system
is on, the GPS turn off when the camera’s metering system is off.
CAMERA SETTING
In the camera setting, the GPS item in the setup menu contains two options as below:
Auto Meter-Off (1) –Enable
When select GPS > Auto meter-off > Enable in the Setup menu, the exposure meters will be turned
off automatically according to the time specified(2) in the camera menu. This reduces the drain on the
battery but may prevent GPS data from being recorded if the exposure meters are not activated until
immediately before the picture is taken. Check that the GPS icon is displayed before shooting.
Remark
(1) Auto meter-off is only available for D4, D3, D3s, D3x, D800, D800E, D700, D300 and D300s and is not available for D2X,
D2XS, D2HS and D200.
(2) Time specified will be overridden by Auto Meter-off delay function in the camera when GPS data cannot be acquired in the
specified time. Auto Meter-off delay allows the camera time to acquire GPS data, the delay is extended by up to one minute
after exposure meters are activated or the camera is turned on.
Auto Meter Off –Disable
Exposure meters will not turn off while a GPS unit is connected. GPS data will always be recorded.
The drain on the camera battery can be reduced by turn off the camera when not in use.

RECORDING GPS DATA (II)
Each satellite broadcasts a digital message that contains two types of information. One type is
ephemeris data, which includes the assigned serial number of the satellite, the status of the satellite
(healthy or faulty), current date and time. The second type is almanac data and includes precise
orbital position of every satellite in the system.
At the initial stage, ECO PF1 GPS needs all these data for the position fixed. It usually takes a minute
to few minutes to receive all data. An open sky outdoor environment will enable faster acquisition
process. It will take a longer time at a weak signal environment. Once ECO PF1 GPS locks to the
satellites, it will take a few seconds for reacquisition even at weak signal environment.
The EASY™ function is Embedded Assist System for quick positioning. ECO PF1 GPS will calculate and
predict automatically the single emperies (Max. up to 3 days) when power on, and save the predict
information into the memory, ECO PF1 GPS will use these information for positioning if no enough
information from satellites, this function will be helpful for positioning weak signal environment.
Before the EASY™ function works properly, ECO PF1 GPS needs to collect enough information from
satellites. The GPS usually needs 1-2 minutes to collect all information from satellites after the first fix.
Please let the GPS turn on for 1-2 minutes after the first fix for the first time of use.
ECO PF1 GPS has a memory backup capacitor inside. The capacitor can provide about two minutes
power to the internal memory after disconnect from the camera of changing battery. To avoid the
lost of ephemeris data in the internal memory, ECO PF1 GPS should be connected to the camera all
the time. The internal memory only consumes a very small amount of energy, it will not affect the
battery life of the camera. As the ephemeris data only be good for 3 days maximum, ECO PF1 GPS
should be disconnected from the camera if the camera will not be used for a long period of time.

LAST POSITION RETENTION (“LPR”)
ECO PF1 GPS is able to provide the last known GPS position with current UTC date / time to the DSLR
camera even if there is the GPS signal is lost or the unit is out of the GPS coverage.
No fix will be reported when no GPS position. The camera’s GPS icon will flash and no GPS
data will be recorded.
A first fix is needed during initialization before the LPR works properly.
Current GPS position will immediately be reported to the camera once the new fix available.
Last known GPS position with current UTC date / time will be continuously reported when
the GPS signal is lost, the unit is out of GPS coverage, until there is a good position fix.
The LPR function works only when the camera is on with the Auto meter-off disabled, the
last known position will be cleared once the power turns off.
