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.

The invention claimed is: 1. A control system to control a rise rate or a descent rate of a free-floating lighter than air platform comprising a vent actuator, an altitude sensor, a processor located on the free-floating platform, a termination controller adapted to terminate a flight of the free-floating lighter than air platform, and a device that controls the vent actuator, wherein the processor comprises stored, programmed or calculated criteria for command and control of the flight of the free-floating lighter than air platform, wherein the free-floating lighter than air platform is without any longitudinal and latitudinal position control. 2. The system of claim 1, wherein the altitude sensor determines both an altitude of the free-floating platform and the rise rate or the descent rate. 3. The system of claim 1, wherein the device determines the rise rate or the descent rate. 4. The system of claim 1, wherein the device is located on the free-floating platform. 5. The system of claim 1, further comprising a ballast container, a ballast and a ballast discharge actuator that controls a discharge of the ballast from the ballast container. 6. The system of claim 5, wherein the ballast comprises a byproduct of a reactant used for generating a gas that is vented into the free-floating lighter than air platform using the vent actuator. 7. The system of claim 1, wherein the processor is coupled to the altitude sensor. 8. A method of controlling a rise rate or a descent rate of a free-floating lighter than air platform by a control system comprising a vent actuator, an altitude sensor, a processor located on the free-floating platform, a termination controller adapted to terminate a flight of the free-floating lighter than air platform, and a device that controls the vent actuator, wherein the processor comprises stored, programmed or calculated criteria for command and control of the flight of the free-floating lighter than air platform, the method comprising determining the rise rate or the descent rate and controlling the rise rate or the descent rate, wherein the free-floating lighter than air platform is without any longitudinal and latitudinal position control. 9. The method of claim 8, wherein the controlling the rise rate or the descent rate comprises venting the vent actuator by the device. 10. The method of claim 8, wherein the altitude sensor or the device determines the rise rate or the descent rate. 11. The method of claim 8, wherein the device is located on the free-floating platform. 12. The method of claim 8, wherein the rise rate control system further comprises a ballast container, a ballast and a ballast discharge actuator that controls a discharge of the ballast from the ballast container and wherein the controlling the rise rate or the descent rate comprises discharging the ballast from the ballast container. 13. The method of claim 12, wherein the ballast comprises a byproduct of a reactant used for generating a gas that is vented into the free-floating lighter than air platform using the vent actuator. 14. The method of claim 8, wherein the processor is coupled to the altitude sensor.
