+The GPS module is certified to operate up to -40 degrees.
+When you first power on the GPS module, you will need to get a fix. If you take power away, the superCap will hold the fix information for a couple of hours. When you restart within a couple of hours, you will get a fix very quickly. However, if the power is off for longer than a few hours, you will need to start the fix process again.
+An external antenna will increase the reception greatly.
