      abstract     = {The NDMC (Network for the Detection of Mesospheric Change)
                      is a global network of measurement sites dedicated to the
                      surveillance of the mesopause region. One main objective of
                      the network is the early identification of climate signals.
                      A key parameter is the mesopause temperature which can be
                      derived from the emission spectrum of a layer of
                      vibrationally excited hydroxyl (OH) at an altitude of
                      approximately 87km. Foremost, emission lines in the SWIR
                      regime between 1520nm and 1550nm are of interest for remote
                      temperature sensing. This report deals with the development
                      of a new generation of GRIPS instruments, which are commonly
                      employed for the observation of mesopause temperatures. The
                      new prototype demonstrates how the application of so called
                      Spatial Heterodyne Interferometers (SHI) can overcome the
                      limitations of currently used grating spectrometers, in
                      terms of spectral resolution and optical throughput. The
                      presented prototype proposes improvements in optical
                      throughput and spectral resolution of about one order of
                      magnitude, significantly reducing the uncertainties of the
                      measured mesopause temperatures. Furthermore, an SHI can be
                      built in monolithic configurations which are aligned and
                      characterized once during assembly without the need of
                      realignment at the measurement site. This makes SHI based
                      instruments ideal for mobile applications.},
