GLISTIN Captured Image

Initial engineering test flight imagery.

GLISTIN-A

Remote Sensing Solutions (RSS) and the Jet Propulsion Laboratory (JPL) teamed to design and build the Airborne Glacier and Land Ice Surface Topography Interferometer (GLISTIN-A). Planned for deployment this summer as part of the UAVSAR configuration on the NASA Gulfstream III aircraft, this new system will provide single pass ice surface topography mapping over 10 km swath with 10 cm to 50 cm resolution.

The original system (GLISTIN) was developed through the NASA International Polar Year program in which RSS and JPL first demonstrated the capability of airborne Ka-band interferometry to provide wide-swath topography. GLISTIN-A's unique use of solid-state technology and ping pong geometry produces a very compact sensor that is deployed directly on the UAV SAR panel, external to the aircraft fuselage, and will be compatible with deployment on the NASA Global Hawk UAV and other high altitude platforms.

iRAP

The RSS Internet-based Radar Digital Receiver and Processor (iRAP) system is a high fidelity, modular processing system for radar applications. Easily reconfigurable at both hardware and firmware levels, it provides a cost effective solution that can be optimized for each application.

With its Linux-based network processor, it provides multiple independent gigabit Ethernet interfaces to other systems and client applications. Its FPGA-based processing cards can implement a variety of tasks including, multi-channel digital receivers, waveform generation, Doppler / spectral processors and synthetic aperture processing. With interchangeable mezzanine cards, each FPGA processor module can be configured with different external interfaces.

iRAP's unique mesh system architecture provides ultra high-speed data communication between its processing cards allow for complex parallel processing. Through a switch fabric PCIe module and embedded DMA engines on the FPGA cards, data and products can be passed through the network processor to client applications, network storage, and downstream processing applications at rates exceeding 120 MB/s per network interface.

Its conduction cooled design is very compact and can operate at altitudes up to 70 kft. The system has been deployed on the NASA Global Hawk UAV and NASA ER-2 aircraft. iRAP was developed wiht funding from the NOAA SBIR program and the NASA IIP.

HIWRAP

Remote Sensing Solutions (RSS), NASA Goddard Space Flight Center (GFSC) and the University of Massachusetts (Umass) teamed through the NASA Instrument Incubator Program to develop the High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) for deployment on the NASA Global Hawk and other high altitude aircraft. The HIWRAP is a solid-state conical scanning, dual-frequency, dual-beam Doppler radar. It acquires volume and surface backscatter profiles simultaneously at Ku and Ka-band wavelengths and two incidence angles (30 an 40 degrees).

From these measurements it maps the 3-dimensional tropospheric and atmospheric winds, ocean vector surface winds and precipitation field in and around tropical cyclones and severe ocean storms.
To achieve high sensitivity and overcome range-Doppler ambiguities, HIWRAP uses a novel transmit waveform (frequency diversity pulse compression) developed through a RSS NASA STTR project. HIWRAP has been deployed on the Global Hawk in the NASA Genesis and Rapid Intensification Processes (GRIP) experiment and on the NASA ER-2 in support of Global Precipitation Measurement (GPM) Mid-Latitude Continental Clouds Experiment (MC3E). HIWRAP is to participate on the Global Hawk in the multi-year hurricane study (HS3).

D3R

Leveraging a novel transceiver and waveform design developed during a RSS NASA Phase II project, Remote Sensing Solutions, Colorado State University and NASA Goddard Space Flight Center teamed to develop the Dual-wavelength, Dual-polarized Doppler Precipitation Radar (D3R). This innovative solid-state radar systems is serving as a calibration/validation radar system for the Global Precipitation Measurement (GPM) mission.

It acquires dual-polarized Doppler and reflectivity precipitation volume backscatter measurements simultaneously at Ku and Ka-band wavelengths. Utilizing frequency diversity pulse compression approach, it achieves sensitivity close to traditional tube-based precipitation radars while suffering no blind region. Internal calibrations enable the system to maintain better than 0.1 dB stability.
