Laser interferometry high-precision tracking for LEO
The GSP study “Laser Doppler Interferometry Mission for Earth Gravity”, has identified a number of technological criticalities
for LEO laser interferometry high precision tracking. The laser beam steering mechanism needs to be further investigated. In
particular, repeatability of the beam pointing calls for a testing activity to ensure reliable results. Another issue is the final
implementation of the laser interferometer: a heterodyne interferometer with amplitude modulation scheme has been proposed
to mitigate photo-detector noise issues and proof-of-concept tests have been performed that confirm feasibility. Additional
tests with state-of-the-art components and, possibly longer baselines, are needed to demonstrate the required performances.
Deliverables:
Test-bed demonstrator of critical technologies.

Title:
T103-27MM
Large format APS detectors with on-chip intelligence for lightning imaging
The Lightning Imaging Mission is intended for continuous mapping of lightning discharges during both day and night, into a
geostationary orbit. Detection on a geostationary earth disk basis, real time observation of the total lightning flash activity
represents valuable improvements for all operational applications. From geostationary orbit, the sensor will be capable of
detecting all forms of lightning with a high spatial resolution and detection efficiency. Since this data will be distributed in real
time, it will be an invaluable tool to aid weather forecasters in detecting severe storms in time to give advance warning to the
public. The lightning imagery mission will also support applications in atmospheric chemistry, as lightning plays a significant
role in generating nitrous oxides. The natural nitrous oxide budget is a matter of great uncertainty at this time, and long-term
observations of one of its sources will prove valuable as the subject develops.
The selected observation technique is based on the detection of the strongest lightning emission feature within the cloud top
optical spectra produced by the neutral oxygen line at 777.4 nm.
