ASTRA is a ground based air defence system designed for SHORAD SAM, AAA and MANPADS forces. GBAD forces and weapon systems are controlled from ASTRA mobile command post (MCP) located on a tracked vehicle and equipped with hardware and LETVIS AD software designed for C3I systems applications. ASTRA C3I system provides the commander with accurate and timely information required for effective control/employment of short range SAM (optionally medium range SAM through modification of SW and communication equipment), MANPADS, and AAA weapon systems.

>track data receipt from PSR
>ASTRA fire units position/status data transfer to MCP ASTRA – for system database reconfiguration
>ASTRA fire units positioning via GPS
>processing of radar data received from higher command level
continuous air situation analysis for air threat assessment, establishing air defence priorities and a flexible countering air attacks
>support to commander decision-making process for timely employment of most suited weapon system in terms of its >capabilities, location and sustainability
>recognized air picture dissemination to MCP workstations for air defence operations
>fire units tasking within the GBAD cluster
>co-ordination with the Air Force for tasking of AD aircraft
>operation control and monitoring of workstations and associated equipment, weapon systems status as well as continuous supervision of data links
>monitoring and record/archiving of operator activities during each mission, creation of documentation in electronic form
>combat simulation and operator training
