Abstract

A method and apparatus for measuring depth of waterways and elevation of land features through autonomous consolidation of GPS device data acquired from a plurality of mobile platforms is disclosed. The GPS device data may then be processed and compared to published reference data. A data recorder and a wireless transmission system comprise an onboard unit, which serves to interface with the GPS device for collecting, recording and transmitting data. The onboard device also provides an apparatus for collecting other georeferenced data from multiple mobile platforms, and serves as a node on a two-way meshed communication network.

Claims

1. A system for collecting and processing location data comprising:

a vehicle comprising;

a global positioning system (GPS) device; and

a data collection device in communication with the GPS device;

wherein the data collection device collects position data from the GPS device and is configured to transmit the position data to a remote data station.

2. The system of claim 1, wherein the GPS device is in communication with a vertical sensing device, the vertical sensing device configured to receive elevation or depth data.

3. The system of claim 1, wherein the GPS device is in communication with a sensor configured to receive other data of interest.

4. The system of claim 2, wherein the vertical sensing device is selected from the group consisting of augmented GPS, radar, altimetry, sonar, and combinations thereof.

5. The system of claim 2, wherein the data collection device is configured to receive at least one of time, horizontal position, elevation, depth, heading, speed, environmental data, platform status, and quality of information data.

6. The system of claim 1, wherein the data collection device comprises:

a data interface module;

a data storage module; and

a wireless transmission module,

wherein the data interface module is in communication with the GPS device and the data storage module and wherein the data storage module is in communication with the wireless transmission module, the wireless transmission module being configured to transmit the position information to a remote data station.

7. The system of claim 1, wherein the vehicle is selected from the group of air vehicles, land vehicles, sea vehicles, or combinations thereof

8. The system of claim 1, wherein the data collection device further comprises an attitude sensor module.

9. The system of claim 1, wherein the data collection device is configured to include metadata with the position data, the metadata providing identifying information for the vehicle.

10. A system for storing and transmitting data comprising:

a data collection device comprising;

a data interface module configured to receive location data;

a data storage module configured to store the location data; and

a wireless transmission module configured to transmit the location data,

wherein the data interface module is in communication with the data storage module and wherein the data storage module is in communication with the wireless transmission module.

11. The system of claim 10, wherein the data interface module receives location data from at least one of a horizontal position device and a vertical position device.

12. The system of claim 10, wherein the wireless transmission module transmits location data to a remote data harvesting station.

13. The system of claim 10, wherein the wireless transmission module serves as a two-way communication node for other data collection devices.

14. The system of claim 13, wherein for a plurality of data collection devices, each having a wireless transmission module, the communication nodes form a meshed network.

15. The system of claim 14, wherein the meshed network provides for connectivity between the plurality of data collection devices.

16. The system of claim 14, wherein the meshed network provides for sharing data harvesting station internet connectivity.
