HIGH RELIABILITY RADIATION HARDENED MULTI OUTPUT DC-DC CONVERTER

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- ST-30-11 (ESA).
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 functionality.
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 voltage ripple.

The board outline is LxWxH: 144 mm x 134 mm x 41 mm.

HIGH RELIABILITY RADIATION HARDENED 28V REGULATOR & BATTERY MANAGEMENT

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 battery damage.
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 variation.
The battery charger implements a constant current charge control loop, suitable for lithium-ion & lithium- polymer technologies.
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.

RAD HARD CPCI BASED ON BOARD COMPUTER FOR SATELLITES

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 temperature inputs.
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 payload module.

  • • 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.

INTEGRATED NAVIGATION SYSTEM

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).

Proximity Modem SPACE FLIGHT COMMUNICATIONS MODEM

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 any environment.
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 ground stations.
Designed for hostile radiation environments, such as LEO orbits.
