INTRODUCTION
Thank you for purchasing di-GPS® Mini 3-MTK series GPS receiver (digital images GPS).
di-GPS® Mini 3-MTK series GPS receiver (thereafter “M3-MTK 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.
M3-MTK GPS has built with the latest third generation MTK MT3339 ultra low power consumption
GPS engine. It supports up to 66 channels of satellite tracking with -165dBm sensitivity. M3-MTK GPS
(1)
repeats the last fixed position when no GPS signal is available or the unit is out of GPS coverage with
real UTC date/time.
M3-MTK GPS allows you to save your present location data to your digital image file. Its State-OfThe-Art technology provides extremely fast TTFF (Time-To-First-Fix), unrivaled high sensitivity and
superior performance in virtually any outdoor environment. M3-MTK 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.

HOW TO CONNECT M3-MTK GPS TO CAMERA BODY (1)
Connect the DSLR camera and M3-MTK GPS as described below.
1.
Turn off the camera.
2.
Remove the cap from the 10 pin remote terminal on the camera body.
3.
Connect the 10 pin connector of M3-MTK GPS to the 10 pin remote terminal on camera. Do
not use any extension cord. For exact cable connector of different models, please refer to
Page 5 – Connector Cable of M3-MTK GPS.
4.
Switch the power mode to “On” or “Auto”.
5.
Turn the camera on.
6.
If M3-MTK GPS is properly connected, the camera will display a blinking icon on the top
control panel. It means M3-MTK GPS is searching for a signal. The icon will stop blinking
once signal has been established and M3-MTK GPS is ready for supplying the current position.
7.
M3-MTK GPS will automatically detect the connection of the camera. It cannot be turned on
when the camera is not connected whatever the power mode switch is set to "On" or "Auto".
Both "On" and "Auto" mode only function when the camera is properly connected.
8.
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
which includes precise orbital position of every satellite in the system.
At the initial stage, M3-MTK 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 M3MTK GPS locks to the satellites, it will take a few seconds for reacquisition even at weak signal
environment.
