Configuring position report transmission options
The DZM can transmit GPS positions using three different options:
SMS over the cellular network
SMS or SBD over the Iridium satellite network.
NOTE!
Messaging via the cellular network is currently only supported by TracPlus Global in New Zealand and
Australia. In other countries or with other tracking providers, position reports may only be sent via the Iridium
satellite network.
The cost of messaging differs between these three options:
If messaging via the cellular network is available, this is usually the cheapest option.
When using the Iridium network, SBD is the default mode as it is usually faster and more economic than SMS.
However, if you are only flying a small number of hours, SMS may be more economic.
Your tracking service provider will be able to recommend the most economic option based on your operation.
The DZM is designed to switch between these three options depending on network availability, as shown in the
following drawing, and on the preferences programmed into the DZM.
If the DZM has a cell modem connected,
and
Cell Phone is selected as the preferred device (see page 66),
and
the cell modem has a network lock, then the DZM will first attempt to transmit via cellular SMS
If a message can’t be transmitted via the cellular network, the DZM will send the message via Iridium
If the Iridium SBD service is enabled on the DZM (see page 66), the DZM will first attempt to send the
message via SBD
If the message can’t be sent via SBD (because the Iridium phone is being used for a voice call), the DZM will
send the message via Iridium SMS (messages reports can be sent via SMS even when the phone is in use for
a voice call).
