Abstract

A mobile platform includes a GPS receiver system to collect position related information for storage in a database. Sensors further collect platform operational information for storage in the database. A control processor for the mobile platform collects the stored information for periodic transmission over a wireless communications link to a remote location for further processing and handling. The control processor is configured to periodically engage in data collection from the GPS receiver system and sensors at a first rate and remotely report any interim collected information over the wireless communications link at a second rate. Preferably, the first rate is greater than the second rate by integer multiple to most efficiently and economically utilize wireless communications resources. At the remote location, a central controller receives the mobile platform reported information for processing in accordance with tracking management applications. An interface to the central controller allows a user to control the information collection and reporting operations of the control processor (in the mobile platform) as well as the tracking management functions performed by the central controller.

Claims

1. A system for collecting and remotely reporting mobile platform related information, comprising:

a GPS receiver system operable to collect mobile platform position related information;

a database storing the collected position related information;

a processor operable to control operation of the GPS receiver system to collect position related information for database storage at a first rate, the processor further controlling actions to remotely communicate any interim collected position information from the mobile platform at a second rate, wherein the second rate is a positive integer multiple of the first rate greater than one; and

a transceiver operable to remotely communicate the position related information over a wireless communications link.

2. The system of

claim 1

further including:

a sensor operable to collect mobile platform operational information under the control of the processor at the same first rate, the collected information stored in the database, and the collected information remotely communicated by the processor at the same second rate.

3. The system of

claim 2

wherein the mobile platform position related information and mobile platform operational information are remotely communicated substantially simultaneously at the second rate.

4. The system of

claim 1

further including a timer associated with the processor and operable to time the first and second rates, the processor operating responsive to timer expiration of the first rate to control information collection and storage and responsive to time expiration of the second rate to control remote communication of the information.

5. The system of

claim 4

wherein the GPS receiver system generates a GPS time reference to which the clock is synchronized.

6. The system of

claim 5

wherein the first rate comprises an X time period and the second rate comprises a Y time period, and wherein the processor determines expiration of the first and second rate by counting modulo X and Y, respectively.

7. The system of

claim 4

wherein the processor delays remote communication of the information following expiration of each consecutive second rate by an offset time period.

8. The system of

claim 7

wherein the offset time period is a randomly or pseudo-randomly selected time delay.

9. A mobile asset tracking system for use with a plurality of mobile platforms, comprising:

a central data collection center monitoring the plurality of mobile platforms; and

each of the plural mobile platforms including;

a GPS receiver system operable to collect mobile platform position related information;
