Abstract
Innovative new methods in connection with lighter-than-air (LTA) free floating platforms, of facilitating legal transmitter operation, platform flight termination when appropriate, environmentally acceptable landing, and recovery of these devices are provided. The new systems and methods relate to rise rate control, geo-location from a LTA platform including landed payload and ground-based vehicle locations, and steerable recovery systems.
Claims30
A method to determine a location of a device transmitting wireless signals to a plurality of lighter-than-air (LTA) platforms, the method comprising
- taking signal path delay measurements from the plurality of LTA platforms;
- determining the location of the device transmitting wireless signals based on the signal path delay measurements;
- and
- communicating the location of the device transmitting wireless signals to an LTA platform.
A method to determine a location on the earth of a device transmitting wireless signals comprising a GPS unit, the method comprising:
- measuring a location of the device transmitting wireless signals by the GPS unit;
- determining that the device transmitting wireless signals is stationary on the earth;
- and
- communicating the location of the device transmitting wireless signals to a lighter-than-air (LTA) platform.
A method to determine a location of a device transmitting wireless signals to one or more (LTA) platforms, the method comprising:
- taking signal path delay measurements from an LTA platform at different intervals of time;
- determining the location of the device transmitting wireless signals based on the signal path delay measurements;
- and
- communicating the location of the device transmitting wireless signals to the LTA platform.
