Enhancing Reception Of Signals In Global Positioning System (Gps) Receiver Module

US Patent:
7986269, Jul 26, 2011
Filed:
May 14, 2010
Appl. No.:
12/780797
Inventors:
Ralph M. Kling - Sunnyvale CA, US
Darren S. Liccardo - San Jose CA, US
Michael J. Grimmer - San Jose CA, US
Assignee:
Crossbow Technology, Inc. - Milpitas CA
International Classification:
H01Q 3/02
US Classification:
342374
Abstract:
An antenna assembly for receiving the GPS signals in a global positioning system (GPS) receiver module automatically orients the antenna to better receive the GPS signals. The antenna is oriented by a positioner (e. g. , a counterweight) that automatically rotates a frame on which the antenna is mounted. The GPS receiver module may also include multiple antennas oriented in different directions to maintain good reception of the GPS signals in any position. The multiple antennas are oriented in a manner so that the poor reception range an antenna is covered by other antennas. Signals from multiple antennas may be combined or chosen for processing by a GPS processor. Also, multiple GPS receiver modules may be deployed in close proximity so that wireless communication between the GPS receiver modules may be established.

Enhancing Reception Of Signals In Global Positioning System (Gps) Receiver Module

US Patent:
8077082, Dec 13, 2011
Filed:
Jan 14, 2008
Appl. No.:
12/013860
Inventors:
Ralph M Kling - Sunnyvale CA, US
Darren S Liccardo - San Jose CA, US
Michael J Grimmer - San Jose CA, US
Assignee:
Crossbow Technology, Inc. - Milpitas CA
International Classification:
G01S 19/42
US Classification:
34235725
Abstract:
An antenna assembly for receiving the GPS signals in a global positioning system (GPS) receiver module automatically orients the antenna to better receive the GPS signals. The antenna is oriented by a positioner (e. g. , a counterweight) that automatically rotates a frame on which the antenna is mounted.

Signals from multiple antennas may be combined or chosen for processing by a GPS processor. Also, multiple GPS receiver modules may be deployed in close proximity so that wireless communication between the GPS receiver modules may be established. The GPS receiver modules with good GPS signals reception may determine its location and send its location information to the GPS modules with poor or no signal reception. The GPS receiver module receiving the location information from other GPS receiver modules may take the location as indicated in the received location information as its location or process the location information further to determine its location.
