GPS Testing
You can perform GPS preconnection tests before you connect
to the Sprint network. Your device’s GPS receiver must be
locked on to at least three orbiting satellites to calculate a 2D
position (latitude and longitude) and track movement. When
it is locked on to four or more satellites, the GPS receiver can
determine your 3D position (latitude, longitude, and
elevation).
ᮣ Click the Test GPS button to perform the test. The
number of satellites found, your HEPE (horizontal 3D
estimated position error), latitude, longitude, and
elevation will be shown in the box to the right of this
section.
Note:
Sometimes geomagnetic disturbances in the earth’s
atmosphere and sunspots can affect the ability to fix on your
position. If you are within Sprint’s coverage area and still
cannot connect, such factors may be the cause.
