Hermes Manual 1.0.1
General Description
The Hermes is a handheld asset tracking beacon which continuously monitors for asset location
and reports and receives location via the Iridium satellite network. Hermes makes use of the bi-
directional, global, real time Iridium Satellite Short Burst Data (SBD) network in combination with
GPS position location.
Inside the Hermes is a 9603 Iridium satellite Short Burst Data core radio transceiver, a specialized
low-power Xeos digital controller with GPS, Iridium & GPS antennas, and rechargeable Lithium
battery.
While the Hermes is intended for recovery of remote deployments, Xeos Technologies Inc. (Xeos)
manufactures other products for fixed location monitoring and remote tracking and surveillance.

Theory of Operation
The Hermes is intended for the recovery of other Xeos products on deployment. Utilizing
XeosOnline’s message forwarding system, up to 10 devices can be set to forward location
information to the Hermes.
The internal GPS of the Hermes determines its own location, and derives the bearing and distance
between the Hermes and forwarded deployed assets. The most recent position of each deployed
asset is stored and can be cycled through on the display of the Hermes. The position of the
Hermes is also updated regularly to make bearing and distance as accurate as possible.
When coupled with a chart plotter and appropriate cable, the Hermes can output position data
of its own position or those of the tracked assets as a standard NMEA-0183 TLL message for
added tracking ability.
