Hermes Manual 1.0.1 

and will always have their code name (ex. Transfer OK) next to 
this number. 

Message Size (bytes) 

The  size  of  the  actual  message  sent  by  the  Iridium  device, 
which is in the attachment in the email. 

*Unit Location 

The Doppler position of the device as estimated by Iridium’s 
network. It is 

NOT

 the GPS position measured by the device.  

*CEPradius = 2 

The  numerical  value  of  how  accurate  the  above  position  is; 
with a value of 2, 

This means that using the Lat/Long that the 

body has supplied, Iridium is 80% confident (always 80%) that 
the device sending the message is within a circle, 2 kilometers 
in radius, with the Lat/Long given as the center of that circle. 
The  higher  the CEPradius value,  the  larger  the  circle  and 
therefore the less accurate that position.

 

*These items can be enabled/disabled by your Iridium provider if desired. 

Global Positioning System 

Location information generated by the device itself is embedded in the SBD attachment sent via 
the Iridium Gateway and can only be seen through the XeosOnline system or situations where 
the position information is sent in a plain-text format (XeosOnline message forwarder or using 
the $msgenable command). This position information is accurate to within several feet of the 
true position.
