29About Positioning by GPS“Positioning” refers to calculation of your current position from the satellite orbit informa-tion and radio propagation time. At least 3 satellites need to be acquired for successfulpositioning. If positioning fails, move away from buildings as far as possible and standin an area with open sky.• About errorsThe measurement environment may result in positioning errors of several hundredmeters. Under favorable conditions, positioning can be performed successfully usingonly three satellites. However, under the following poor conditions, the positioning ac-curacy can decrease or positioning can fail.• Between tall buildings• Narrow paths between buildings• Indoors or near large buildings• Under elevated roads or high voltage power lines• Between trees such as in forests or woods• Inside a tunnel or underground• Through heat reflective glass• Areas with strong magnetic fields• When not in use for a long timeWhen using the GPS functions for the first time after purchase, or when it has beenunused in a while, a few minutes may be required to acquire the satellites. Also, if theGPS function has been turned OFF for several hours, a few minutes may be requiredto search for satellites.Saving GPS Information (GPS Log Function)The GPS position information can automatically be saved periodically onto a microSDmemory card. Using the saved data, tracks can be displayed on commercially availablemap software*.* Technical support for the map software is not provided by YAESU.1. See “Activating the GPS Function” on page 28, and activate the GPS function.2. Press and hold the [DISP] key  touch [CONFIG]  [7 GPS LOG].3. Rotate the DIAL to select the GPS data logging interval.OFF / 1 sec / 2 sec / 5 sec / 10 sec / 30 sec / 60 sec4. Press the PTT switch to save the setting and return to normal operation.The GPS log function is activated, and GPS log“ ”icon will be displayed.• The position information is saved periodically unless “OFF” is selected in step 3 (shownabove) or the power of the transceiver is turned off.• Reselecting the GPS data logging interval in step 3 or turning on the transceiver again,begins saving the GPS data under a different file name.
