Hello Beau,
The IridiumSDB source in LRGS listens for a connection from the gateway
(specifically the gateway initiates the connection to the LRGS, not the
other way around). So the data will come from whichever gateway handles the
particular device you're getting data from. Looking through the Iridium
documentation it looks like the IPaddress/hostname of the receiving system
(your LRGS in this case) is set when the remote device is provisioned or by
the owner of the device. If you didn't provision through the DoD, data
would likely go through the Hawaii gateway.
As for formats, someone more knowledgeable about iridium itself will need
to provide guidance but the Iridium data source in LRGS will handle the
baseline date that all devices may send (the IMEI, lat/long, etc). All LRGS
would do is save the raw message provided by the device, you would need to
create a DECODES script to handle whatever the actual format is. If there
are already industry standards though hopefully someone will be kind enough
to share a DECODES script if they have one.
If you aren't the provisioner of the device though, or the provisioner
won't set your IP as a destination, you'd have to coordinate with them how
to get data into your LRGS.
I did see an option in the Iridium docs about having the gateways send the
data through email, which would help with organizational firewall rules;
however, we don't currently support email as an LRGS data source.

Hoping someone might be willing to reach out and give me some advice
setting up an iridium based LRGS for openDCS. The documentation is pretty
sparse and we are having some trouble getting things off the ground. In
particular I'm trying to discern if the Iridium LRGS pulls from the DoD
(Hawaii) or civilian (Arizona) gateway, furthermore - does the LRGS require
a specific format (DoD -PECOS vs industry proprietary formats)? And lastly,
can DECODES be utilized to decode the messages and does anyone have any
experience setting up the configurations for this whichever format is being
utilized.
Thanks in advance for any advice or hints anyone is willing to pass along,
