The actual isolated DC-DC converter is a low to
medium power radiation hardened device of high
reliability designed for hostile radiation
environments, such as those encountered by LEO satellites.
All components are fully derated to meet the
requirements of EEE-INST-002 (NASA) and ECSS-Q-
The DC/DC converter has four positive outputs
(more outputs could be added, or replaced by
negative outputs). Each one is independently
regulated via linear post regulators. The outputs
are sequenced during turn-on and turn-off, so that
the main output is available only after the other
outputs have been established and goes off before
the other outputs have decreased. The converter
incorporates a fixed frequency power converter
and internal EMI filter that meet the requirements
of most major satellite power buses. The converter
includes input under voltage shut-down
Due to the linear post regulation of the outputs,
the converter is well suited for RF-applications
where low noise, high output voltage accuracy and
high CS attenuation is required. In addition, the
converter can feed high-power pulsed loads, as
radar RF power stages with excellent output

The STI-MTR-L-35W is a dual channel LDMOS power
amplifier based on L-band transmitter and receiver
module designed for pulsed radar applications with
electronic steering capability. The module is
intended to be used as the basic building block for
active phased array radar systems.
The Voltage Regulator & Battery Management (VREG)
interfaces the solar array and a lithium-based battery
to conform a semi-regulated power distribution bus in
a direct transfer energy configuration.
Based on sequential switch regulator VREG control,
the average current value in bus limited avoiding
VREG can work without a digital platform support,
avoiding extra hardware.
Bus voltage value set at 28 v, which can be changed in
fly via onboard computer (optional).
The VREG can accommodate to a total power output
of 400W to 850W with minimum component
The battery charger implements a constant current
charge control loop, suitable for lithium-ion & lithium-
Up to 16 pre-conditioning analog measurements,
including battery telemetry (current, intermediate
voltage and 3 thermal status) are available.
Fuse based protection to avoid the bus short-circuit in
case of switch failure.
The STI-OBC-700 is an On-board Computer (OBC) for
SABIA-Mar payload module specifically designed to
meet subsystem specific requirements.
These requirements are mainly large count of high-
speed interfaces, and sensing of voltage, current and
The proposed architecture is based on a Leon3FT
processor on a cPCI bus. The microprocessor (placed
on a main board) controls and monitors the different
specialized boards that perform the acquisition of
signals and counts on the interfaces to manage the
• The OBC housing outline is LxWxH: 380 mm x 240 mm x 240 mm.
• The CBE mass is 18 kg.
• This configuration includes a nominal and a redundant OBC within a common housing.
The Integrated Navigation System is a complete
navigation solution that combines measurements
from an inertial measurement unit, a magnetic
compass, and a GPS receiver in a real-time navigation
algorithm to provide position, speed and attitude
information. The system is specifically designed to
operate in the harsh aeronautical environment.
The inertial measurement unit is thermally stabilized
and provides accelerometer and gyroscopic digital
data on all three axis.
The system has flown over two years in CoNAE's
airborne L-band synthetic aperture radar (SARAT).
The Proximity Modem is a highly flexible design
communications modem, which can be accommodated to multiple mission scenarios,
including inter-satellite and Earth-satellite link slant
range up-to 100.000 Km.
As it is able to work under CCSDS Proximity-1
protocol, it allows the user to customize its
parameters in-orbit, (e.g. duplex mode, datarate,
codification rate, frequency channel, and QoS type,
among others) and to adapt itself to the needs of
Due to its intermediate frequency output, the
module can be connected to either UHF/S or X-Band
interface radio (IR), including the IR provided by the
Designed for hostile radiation environments, such
as LEO orbits.
6 Dof simulator intended to be used for spacecraft
orbiting around the earth. Primarily used to evaluate
the performance of different sensors and actuators in
relation to their capability and also their position in
