US Patent:

57266638, Mar 10, 1998

Filed:

Oct 22, 1996

Appl. No.:

8/734989

Inventors:

Christopher Kent Moyer - Scottsdale AZ
David Moon Yee - Scottsdale AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G01S 502

US Classification:

342419

Abstract:

Survival radio interrogator (1) transmits upon request a message including an identification of survival radio (3). Upon receiving and processing this message, survival radio (3) determines its position from the Global Positioning System and transmits a message back to the search aircraft (2) with the survival radio interrogator (1). The processor (10) of the survival radio interrogator 1 determines a range and bearing of the survival radio (3) and processes data from the survival radio 3 which data includes identification, position and messaging information for display on the LCD display 14. All message transmissions are conducted via the aircraft's (2) radio/intercom system (30).

H04B 7185
G01S 502

US Classification:

342357

Abstract:

A GPS based search and rescue system utilizes an airborne interrogation unit for extending the range of a second interrogation unit. The airborne unit relays communication between a survival radio and the second interrogation unit. The second interrogation unit is typically a ground based unit and is arranged to provide GPS correction information to the survival radio. The normal line of sight communication between a survival radio and an interrogation unit is extended to an over the horizon communication path by utilizing the airborne interrogation unit as a relay for communications.

US Classification:

34235709

Abstract:

A survival radio of the type useable in search and rescue operations and carried by the party to be rescued is described. The survival radio includes a GPS receiver, a transceiver and a microcontroller. The microcontroller responds to interrogation messages containing a predetermined identification code for the survival radio to cause a transceiver to transmit a geographic location of the survival radio as derived from GPS signals.
