B. Introduction
MG-950d is marvelous Sport GPS with data logger. The chip designed based on SiRF Star
III LP which provides the high sensitivity for personal navigation and the wireless Bluetooth
transmission in the world.
This new gadget with LCD monitor is ideal for biking, driving and long journey. User could
easy to view the screen while workout such as total mileage/kilometer, moved time,
elevation and speed. This new device is compact and easy to carry.
MG-950d is a small, robust unit that records NMEA position data from a GPS. It is really
convenient, economical alternative to using a laptop computer especially on long road.
Simply connect the logger to a GPS during your trip then download the track data to a PC.
Also, our photo map part is one of brilliant function, User could match photo in certain
waypoint by their own which show on Google earth.

E. Operational characteristics
Initialization
Once the initial self-test is complete, MG-950d start the process of satellite acquisition and
tracking automatically. MG-950D takes about 45 seconds to achieve a position fix in normal

8
circumstances. After a position fix has been calculated, valid position, velocity and time is
transmitted over the output channel.
Also, our MG-950d records NMEA position data from a GPS. It is really convenient,
economical alternative to using a laptop computer, especially on long road. Simply connect
the logger to a GPS during your trip then download the track data to a PC.
