Patent ID: 7646295

Claim:
An asset tracking system for use on an asset transporter carrying an asset load, a form of said asset transporter precluding attachment of a device above said asset load, comprising: a mobile terminal that is affixed to said asset transporter at a location on said asset transporter whose visibility to a satellite is reduced when a particular orientation of said asset transporter causes the asset load on said asset transporter to be between said mobile terminal and said satellite; a first antenna coupled to said mobile terminal for receiving signals from said satellite, said first antenna being positioned on a first side of said asset transporter; and a second antenna coupled to said mobile terminal for receiving signals from said satellite, said second antenna being positioned on a second side of said asset transporter different from said first side, said positioning of said first antenna on said first side of said asset transporter and said second antenna on said second side of said asset transporter causing at least one of said first and second antennas to have a relatively unobstructed view of said satellite for every orientation of said asset transporter relative to said satellite, said positioning of said first and second antennas on said asset transporter assuring that the asset tracking system receives satellite signals in said mobile terminal using at least one of said first and second antenna regardless of an orientation of said asset transporter relative to said satellite.
