How to Hold the
Receiver
Tracking satellites with your receiver requires that you use the
receiver outdoor and hold it in an appropriate manner.
The receiver will have the best view of the sky when you hold
it at an angle of 30 to 45 degrees (38° ideally) from
horizontal and not too close to your body.
You can check that your receiver is tracking enough satellites
by running the GNSS Toolbox, and more particularly the
GNSS Status function (see GNSS Status on page 33). When
enough satellites are tracked, you can start using your
receiver and run your application software.
Switching to
Suspend Mode
Switching the receiver to Suspend mode is the right thing to
do when you need to make a short pause in your work and you
want to save the operating time of your battery. You should
not however switch the receiver to Suspend mode when it is
collecting raw data.
In Suspend mode, GNSS reception and the modem are off.
The receiver is idle, using the minimum of energy required to
save the use context. The Power & Battery LED flashes green
every 5 seconds or so.
To switch to Suspend mode, just press briefly on the Power
button [8].
