Avionics Suite Design and Manufacturing Capabilities

SATUMA is a pioneer in South Asia for development of Digital Flight Control Systems (autopilots) for precise control of UAVs. SATUMA has created it’s autopilot with the need for total UAV control in mind. Our hardware offers numerous interfaces to flight control components, payloads and data links and has been carefully engineered to provide the maximum capability with the least amount of power, space and weight requirements.

Using an advanced architecture, SATUMA’s Avionics System offers a degree of adaptability and user-friendliness that cannot be found in other application specific designs. Surface-mounted components and industry standard electronics packaging techniques have been utilized to ensure rugged, professional hardware made to survive in real-world operating environments. All software used in SATUMA’s avionics suite has been programmed in ANSI “C” language, providing a robust code with a variety of user-programmable functions.

SATUMA has autopilots suitable for many fixed-wing air vehicles; with minor modifications to the hardware, repackaging for critical fit applications is possible. Similarly, software features can also be reprogrammed to enable tailoring of control functions to meet each customer’s hardware requirements. Autopilot systems have the following features built into them:

• Wing-levelling
• Altitude-hold
• Heading-hold
• GPS Waypoint Navigation (Ground and/or On-The-Fly Re-programmable)
• 12 or 24 volt operations
• Telemetry support

Airframe Design and Manufacturing Capabilities

Airframe Design

Conceptual designing of aircrafts is an integral part of SATUMA’s effort to attain self reliance and independence in the UAV research and development sector. SATUMA’s aircraft configuration development team works in the fields of preliminary, detailed, aerodynamic, and structural design of aircrafts. A variety of performance prediction tools are designed and implemented for each UAV system to optimize its performance for its particular mission requirements. Computational fluid dynamics and flight testing is carried out to validate and improve the design changes.

Composite Construction

SATUMA Airframe design team specializes in lightweight fiberglass structure designing and production for its UAVs. These fiberglass structures are produced using CNC machined molds, and incorporate special features for wing installation, internal equipment mounting, disassembly and shipment. Advanced materials and techniques have been adopted to improve the strength of the airframes and at the same time to reduce the weight.

UAV Systems Support

Maintenance

In close co-operation with the end-user, SATUMA designs and adapts maintenance concepts according to the customer’s needs.
The maintenance activities include:
- Build-up of preventive and corrective maintenance procedures.
- Management of the maintenance build-up for a UAV system.
- Documentation support including writing users and technical documentation.
- Configuration control support includes follow-up of configurations as a result of modifications and changes/upgrades or service bulletins.
- Help desk support to the end-users for the UAV system in question.
- Support during the engineering and purchase of spare parts.

Technical Support

The technical support activities include:
- On-site technical support including all actions from preventive/corrective actions.
- Investigations of failures to practical end-user support.
- Technical support on-mission for flight campaigns including various actions from hands-on practical support up to flight supervision support.
- Production and review of documentation for both technical and tactical functionality verification/validation.
- Evaluation and reporting of verification/validation results.
