How can I obtain GPS?
When connected to your phone, your Summit 2 obtains the GPS signal from the phone.
When the connection between the phone and the watch is disconnected, the watch will obtain a GPS signal on its own.
The initial signal fix may take several minutes. Please ensure that you have a clear line of sight of the sky. Large buildings, trees, and other obstacles might also complicate the connection. Finally, the watch must not be covered by a thick sleeve or similar objects.
How can I get a GPS signal?
Your Montblanc Summit 2 can acquire the GPS signal stand-alone or via the connected phone.
How accurate is the GPS position shown on the device?
When using Montblanc Summit 2, many factors can affect the accuracy of the position, distance, and speed readings that appear on the device. With a strong satellite signal, the GPS position reported by the watch should be accurate to about 3 meters or 10 feet. A weaker satellite signal may decrease that positional accuracy, in turn affecting the accuracy of the distance and speed readings that will be reported.
What steps can I take to minimize GPS inaccuracies caused by environmental factors and GPS drift?
When using your Montblanc Summit 2 in an area such as a densely wooded path or the middle of a city with tall buildings, you may experience a longer time for the device to acquire a satellite signal. Once you've received a satellite signal, you may also see a degraded performance with your GPS track as well as your running/walking pace.
Also, as GPS satellite signals pass through the atmosphere and interact with other environmental factors (such as trees, hills, mountains, buildings, cars, reflective surfaces and more), they can become distorted. In the past, this would often cause a loss of position altogether, but with modern GPS devices that have higher sensitivity receivers, only the weakest signal will prevent the device from locating your position. As a result, GPS drift can occur, causing the device to appear to be moving even though you are standing still.
To minimize these factors it is best to begin the satellite acquisition period when you still have a clear view of the sky, even if you are going to start the activity where the view is more limited. And, if you are going to be stationary for a while, pause the activity during that time to help limit the amount of inaccuracy introduced by GPS drift.
