PRODUCT OVERVIEW

Moog Broad Reach (MBR) Integrated Avionics systems and boards allow build-to-print and custom tailored configurations. The use of existing board designs configured with specific I/O devices can be used as-is or with FPGA modifications in support of spacecraft component and payload needs. Maximizing re-use enables rapid system evolution while minimizing program. This successful design approach is the foundation of the traditional MBR IAU.

Integrated Avionics UnitPRODUCT OVERVIEW

The single board C&DH AJEET is a powerful general purpose processing and I/O platform that can be used for spacecraft flight software, spacecraft and payload I/O processing along with other program unique processing tasks. The AJEET provides all digital and analog interfaces required to support typical small spacecraft Command and Data Handling requirements as well as a powerful payload interface. The BRE440 Rad-Hard by Design power PC based design also offers the users’ access to the Xilinx Virtex-5 reconfigurable FPGA for specific payload or mission specific processing.

PRODUCT OVERVIEW

The Nav-SBR is a very capable single board GPS POD receiver optimized for fast signal acquisition and weak signal tracking capable of operation at LEO and GEO orbits. The MBR Nav-SBR is a single frequency 12 channel GPS receiver ported to a single 3U cPCI card. The Nav-SBR is available as a standalone assembly or as a single 3 U cPCI card for direct chassis integration.

Generated observables are filtered using GPS-Enhanced Onboard Navigation Systems (GEONS) technology under license from GSFC providing high quality solutions employing extended Kalman filter (EKF) augmented with physically representative models for gravity, atmospheric drag, solar radiation pressure clock bias and drift to provide accurate state estimating and realistic state error covariance. MBR’s Nav-SBR GPS receivers very fast un-seeded acquisition time (<1.0 min LEO and <10.0 min GEO), highly precise positional data (<3 m LEO <10 m GEO) and low mass and power provides an elegant solution for spacecraft navigation needs.

Nav-SBRPRODUCT OVERVIEW

McLASI cards provide the H-bridge torque rod drivers (3), analog output drive for reaction wheel control, tachometer and direction sensing, as well as analog and AD590 temperature sensing. Other functions include reporting the switch status, torque rod current, total bus current, and bus voltage. Additionally, if no torque rod interfaces are required the circuitry can be configured as additional low power switches.

PAPIPRODUCT OVERVIEW

The Solar Array and Charge Interface (SACI) hosts the FPGA responsible for battery charge management, power distribution, switch control, telemetry collection and data interface to the IAU computer. The card contains solar array switches, low voltage switches and the floating power supplies. It also contains SC load, battery and solar array current sensors, battery voltage sensor, PRT, and thermistor temperature sensors, along with open collector output interfaces. Variable and fixed timers for identified output switches are included in the SACI FPGA. The voltage sources for the low voltage switch outputs are the side panel-mounted DC/DC converters for the IAU.
