Chapter 5 Learn Geode Connect for iPad and iPhone 51
Owner's Manual
Receiver Mode
These options affect how
the Geode collects and
processes positioning
information, as well as how
it outputs certain types of
data.
■ GPS Only: Enabling this option tells the receiver to only
accept signals from GPS satellites. It stops receiving all
GNSS signals as long as this box is checked. This may
be a useful option in open areas with little interference,
particularly if you are trying to preserve battery life.
■ Mixed: Enabling this option (default) tells the receiver to
use all GNSS satellite signals available to calculate the
position solution. This includes non-GPS satellites, which
do not have DGPS or SBAS corrections. Certain NTRIP
services do provide corrections for non-GPS satellites. For
most applications, Mixed is the best choice, particularly if
there is a lot of interference.
■ NULL NMEA: This option is available because different
navigational apps interpret NULL messages differently. As
a default, when the Geode loses its position (cannot get
a fix), it sends out a NULL NMEA message. Some apps
interpret this NULL message to mean that the Geode’s
position is (0°, 0°), which is west of Africa in the Atlantic
Ocean. If the app you are using starts showing your
position as (0°, 0°), deselecting this option will most likely
correct the problem.
