International Classification:

H04B 7185

US Classification:

34235702

Abstract:

A Global Positioning System includes a ground monitoring network having a plurality of dual frequency receivers that obtain ionospheric delay measurements to provide double difference ionospheric delay residuals. These double difference delay residuals are converted to zero differences based upon a new mathematical technique. The zero differences are fit to measurement epoch specific and transmitter specific mathematical surfaces (i. e. planes). These planes represent precise ionospheric delay corrections in the area of the ground monitoring network for a specific transmitter at the measurement epoch. The planes are then provided as correction information for use by inexpensive single frequency receivers to obtain highly accurate corrections for single frequency receivers by interpolating the correction planes to the location of the single frequency receiver. With this technique higher accuracy surveying results can be achieved with low cost single frequency receivers in real-time or in post-processing than what is currently achievable even with more expensive dual frequency receivers.

342 26R, 343704, 73 2901, 324640

Abstract:

Apparatus and methods for mitigating precipitation effects realized at an antenna system of an instrument such as a microwave radiometer are disclosed. One embodiment of the apparatus includes a blower mechanism that enables instrument operation even during precipitation events (rain, snow, sleet, or excessive condensation) by causing a flow of air at relatively high velocity tangentially across the antenna system. The air flow is of sufficient force to disallow contact by hydrometeors with the antenna or antenna window of the system by redirecting the path of the falling hydrometeors in flight and/or to sweep hydrometeors reaching or formed at the window from the vicinity of the window. Other mechanisms for such precipitation effects mitigation are also disclosed.

US Classification:

73 2901, 7317028, 342 26 R

Abstract:

Apparatus and methods for characterizing atmospheric refractivity and its evolution in time and space utilizing passive radiation emission measurement devices are disclosed. Based on an instrument such as a passive microwave radiometer, ancillary meteorological measurements and other information and observations, the apparatus and methods provide useful signatures for characterizing atmospheric refractivity. The system can observe to any vector in the sky, giving directional as well as zenithal measurements of the refractivity profile, its spatial and temporal gradients, and the spatial and temporal trending of the profile and its gradients.

US Classification:

Abstract:

The space station of the present invention makes use of a modified space shuttle orbiter vehicle to provide a pre-assembled pre-tested, modular space station. The modified orbiter vehicle has all the equipment need for manned launch, re-entry and landing removed. The modified orbiter vehicle carries a pressurized laboratory module, a solar power system, and docking apparatus. The modified orbiter vehicle provides instrumentation, attitude control, communications, and life support systems. Another configuration includes an external fuel tank permanently attached to the modified orbiter vehicle. In either configuration, all equipment is fully integrated, installed and checked out on the ground before the launch in a single unmanned launch. Since the modified orbiter vehicle remains in space as a part of the space station the complexity and weight of the orbiter can be reduced by removing the systems that are required only for manned ascent, re-entry and landing, such as wings, tail, body flap, thermal protection tiles, landing gear, some of the avionics, some crew related controls, displays and hardware.

International Classification:

US Classification:

324 585R

Abstract:

A passive, multi-channel microwave radiometer includes an antenna-lens assembly for receiving, and a first waveguide designed to provide a common path for propagating, 23. 8 GHz and 31. 4 GHZ atmospheric signals. The 23. 8 GHz signal is above the frequency of relative maximum water vapor absorption and the 31. 4 GHz signal is near a relative minimum in the water vapor absorption spectrum. Circuitry is responsive to the atmospheric signals for generating output signals representing the respective water vapor and liquid content in and the temperature of the atmosphere. For realtime calibration a blackbody assembly is mounted in the near field of the antenna-lens assembly. The blackbody assembly emits known blackbody microwave signals at 23. 8 GHz, 31. 4 GHz and in the V band. The radiometer is calibrated during its normal operation by causing a mirror to select the blackbody signals for propagation along the common path.

International Classification:

G01W 100

US Classification:

7317028

Abstract:

An atmospheric water vapor sensing system using Global Positioning Satellites (GPS) to determine the refractivity and Slant-path Water Vapor (SWV) between an Earth-based GPS receiver and a plurality of satellite-based GPS transmitters. Either the refractivity measure or the SWV measure can be input directly into weather forecasting models. SWV is the integrated atmospheric water vapor in a column of atmosphere at an acute angular line-of-sight path between the Earth-based GPS receiver and any one of the plurality of satellite-based GPS transmitters. SWV sensing facilitates atmospheric soundings over land and water to provide global scale high resolution atmospheric tomography for use in operational meteorology and meteorological forecasting.

International Classification:

Abstract:

An atmospheric water vapor sensing system uses Global Positioning Satellites (GPS) to determine the refractivity and Slant-path Water Vapor Delay (SWD) between an Earth-based GPS receiver and a plurality of satellite-based GPS transmitters. The system provides improved precision in position calculation measurements by eliminating the refractivity effects of water vapor. No other system inputs are required apart from conventional GPS satellite signals and conventional satellite orbit data to implement the method. SWD arises from the refractivity in the integrated atmospheric water vapor in a column of atmosphere at an acute angular line-of-sight path between the Earth-based GPS receiver and any one of the plurality of satellite-based GPS transmitters. The system is especially useful in monitoring the Earth's crustal deformation.
