Title:
T603-29ET
Telecommand & Telemetry System Security
This design study will include the following areas:
1. Identification and evaluation of threats and vulnerabilities on current ESA Spacecraft Telecommand and Telemetry systems
with an end-to-end perspective but with particular emphasis on the Space link and considering the particulars of various ESA
missions, e.g. Science, Earth Observation, Manned Space flight, Navigation, Telecommunications.
2. Exploration and definition of technical concepts for security measures at the relevant CCSDS protocol layers to guarantee
adequate levels of availability, authentication, confidentiality, integrity and non-repudiation; particular emphasis shall be given
to: physical and coding layers where current ESA/ECSS standards make no provision for Security and denial-of-service
(jamming) attacks or traffic analysis are a possibility; application, packet, segment and transfer layers for the definition of
authentication and encryption protocols where generic concepts have been documented by CCSDS but not standardised;
particular implementations performed by ESA and other Agencies but either outdated or constrained by the particular mission
and therefore, inadequate for future missions; Consideration of Operational aspects, e.g. key management; Consideration of
Ground Networking aspects, e.g. outsourcing.
3. Selection and detailed study for a case-study mission, e.g. Earth Observation.
4. Derivation of security requirements for equipments and facilities on both Space and Ground Segments.

Title:
Linearity Assessement of GaN Technology
GaN offers the potential for realising state of art power performance. Previous ESA work programmes have shown that there
is a requirement to investigate novel device structures to further enhance transistor performance. The aim of this activity is to
optimise the GaN transistor structure (both physically and from a materials growth perspective) to achieve higher power
performance through the introduction of device architectures known to enhance performance such as field plates, double
hetero-junction channels, recess structures, graded channel doping and new vertical transistor structures. In particular, efforts
will be undertaken to investigate the device and technology trade-off’s required to achieve simultaneous high linearity and high
power added efficiency performance, along with undertaking an assessment of the introduction of the proposed techniques for
improvement of device reliability and manufacturability. This work is an important requirement for future multi-carrier
telecommunications transponders and if successful will allow world class device performance with increased power added
efficiency and linear output power to be achieved compared with GaAs pHEMT technology.
