ABB has recently designed a compact, low-cost and light weight infrared spectral imager. That instrument re-use many
building blocks from ABB’s commercial line of products, repackaged in a system adapted for field operations. That
instrument incorporates limited imaging capacity in order to improve the fill factor and the signal to clutter ratio when
the target is not spatially uniform. The current version operates in the long-wave infrared from 6 μm to 14 μm. Its main
applications include chemical detection and identification, environmental monitoring and LWIR infrared signature
measurements.
Current fleet of geostationary Earth orbit (GEO) satellites are used to provide communication in remote areas and to acquire meteorological data that are fed to Numerical Weather Predictions models.

The Polar Communications and Weather (PCW) mission is proposed by the Canadian Space Agency (CSA), in partnership with Environment Canada, the Department of National Defence, and several other Canadian government
departments. The objectives of the PCW mission are to offer meteorological observations and telecommunication
services for the Canadian North. These capabilities are particularly important because of increasing interest in the Arctic and the desire to maintain Canadian sovereignty in this region. The PCW mission has completed its Phase A in 2011. The PCW Meteorological Payload is a Multi-Spectral Imager (MSI) that will provide near-real time weather imagery for the entire circumpolar region with a refresh period of 15 to 30 minutes. Two satellites on a Highly Elliptical Orbit (HEO) will carry the instrument so as to observe the high latitudes 24 hours per day from a point of view that is almost geostationary. The data from the imagers are expected to greatly enhance accuracy of numerical weather prediction models for North America and globally. The mission will also produce useful information on environment and climate in the North. During Phase A, a certain number of critical technologies were identified. The CSA has initiated an effort to develop some of these so that their Technology Readiness Level (TRL) will be suitable for the follow-on phases of the program. An industrial team lead by ABB has been selected to perform technology development activities for the Meteorological Payload. The goal of the project is to enhance the TRL of the telescope, the spectral separation optics, and the infrared multispectral cameras of the PCW Meteorological Payload by fabricating and testing breadboards for these items. We will describe the Meteorological Payload concept and report on the status of the development activities.
CARVE-FTS is a near-IR Fourier-Transform Spectrometer (FTS) used by the Jet Propulsion Laboratory (JPL) for the
Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE). CARVE is a 5-year mission of intensive aircraft
campaigns in the Alaskan Arctic selected as part of NASA’s Earth Ventures program (EV-1). The CARVE-FTS has
been designed, manufactured and tested by ABB Inc. The objective of this instrument is to provide integrated column
measurements of carbon dioxide (CO2), methane (CH4), and carbon monoxide (CO). The system is inspired from the TSUKUBA-FTS built by ABB for the Japanese Aerospace Exploration Agency (JAXA). JAXA uses the instrument for preparation, calibration and validation within the GOSAT program. The instrument is a Michelson based FTS with three spectral bands. The light modulator is a Michelson single pass type interferometer with large aperture and medium spectral resolution. It provides infrared spectra from 12,900 cm-1 to 13,200 cm-1, from 5,800 cm-1 to 6,400 cm-1, and from 4,200 cm-1 to 4,900 cm-1. This instrument is also able to measure
the scene radiance with S and P polarization simultaneously using monopixel detectors. The instrument is mounted on a
damping platform and is installed in an aircraft. It delivers continuous data for flight campaigns over the Alaskan Arctic.
SNR higher than 100 is reached for each band and the measured ILS full width at half maximum is as low as 0.26 cm-1 at
6,566 cm-1. We present the instrument design, its specification and test results obtained at ABB.
