AccVHDL.pdf "Accelerated Verification of Digital Devices Using VHDL"
This paper presents two aspects for improving the verification
of microprocessors; program-less verification, and methods for
handling large differences in abstraction level between a
reference model and the actual design. Program-less
verification is a type of pseudo random verification where the
notion of a software program executing on the microprocessor
has been abandoned. This paper will be presented at the VHDL
Users' Forum in Europe in Lausanne (CH), September 1998.

AGGA2Intro.pdf "Development of an Advanced GPS GLONASS ASIC"
This paper presents the second generation radiation tolerant
Advanced GPS GLONASS ASIC, the AGGA-2, implementing the core
digital signal processing for combined GPS and GLONASS
receivers. The AGGA-2 supports a wide range of space related
applications, both for single-frequency (C/A- code) and
dual-frequency (both C/A- and P-code) receivers. The paper
describes the principles of GPS operation, followed by a
list of applications supported by the AGGA-2, typical receiver
configurations and an overview of the AGGA-2 functionality.

Iris.pdf "A Single-chip CCSDS Packet Telemetry and Telecommand
Based Microcamera"
By applying the packet telemetry and telecommand standards
endorsed by the European Space Agency (ESA) and the
Consultative Committee for Space Data Systems (CCSDS) to a
microcamera, the need for support from the on-board data
handling system can almost be eliminated. If the microcamera is
designed with interfaces that fully match those of the
telemetry and the telecommand subsystem, the additional
interface components will be reduced to simple transceivers.

on-board spacecraft. This paper introduces the advantages of

each PETRA chip can connect up to 40 analogue or digital
sensors which are sampled at a nominal period between 10 ms
and 50 s. The sensor data is output as CCSDS compliant
Telemetry packets. Several PETRA chips can be cascaded in
a chain, to be able to connect as many sensors as required.

ReadOut.pdf "Miniaturised Microcontroller based Read-out Electronics for
Space Applications"
The Particle Detector Front End (PDFE) ASIC together with an
8052 based microcontroller forms a chip set being developed by
the European Space Agency (ESA) for compact low cost scientific
energetic particle instrumentation. Driving requirements of low
noise and power consumption led to the selection of a single
configurable analogue channel followed by an internal 8-bit
ADC. Low mass and volume necessitated for space applications
require on-chip integration of supporting functions such as
discriminators, independent coincidence event detection and an
efficient serial control interface. This paper was presented at
the 8th European Symposium on Semiconductor Detectors in
Schloss Elmau (G), June 1998.

TeamBullet.pdf "The TEAMSAT Experience: TEAMSAT's Data-Handling Systems"
Twenty-five weeks from project approval to the delivery of two

and the availability of the ESA Telemetry and Telecommand chipset,
a working data-handling system including ground segment was
already available six weeks prior to TEAMSAT's shipment to Kourou.
