SRC has received a $7.2m contract to supply radars for the US Army’s ground-based sense and avoid (GBSAA) programme.

The company’s manufacturing subsidiary, SRCTec, will supply LSTAR radars in order to establish ten GBSAA test sites across the US.

The contract also includes additional options for radars, spares and sustainment.

The GBSAA is a radar and warning system designed to enable unmanned aircraft systems (UAS) operation in National Airspace System (NAS) in compliance with Federal Aviation Administration (FAA) regulations, which require a pilot to be able to ‘see and avoid’ other aircraft flying in the same airspace.

"We are proud that our LSTAR air surveillance radar will be instrumental in the safe operation of unmanned aircraft."

In addition, the system can monitor the location and altitude of the UAS and other aircraft, and also detect possible collisions and subsequently provide the operators with solutions to avoid such collisions.

SRCTec president Drew James said: "This is a very important effort and we are proud that our LSTAR air surveillance radar will be instrumental in the safe operation of unmanned aircraft within the United States."

The LSTAR family of air surveillance radars provides 360 degree, 3-D electronic scanning capabilities for detection and tracking of a broad spectrum of fixed and rotary wing aircraft, such as ultralights, para-gliders, hang-gliders and UAS.

Easily transportable with rapid, unobtrusive emplacement, the radars are claimed to be ideal sensors for border air surveillance, UAS sense and avoid, local airspace management, critical infrastructure protection, as well as wind farm applications.

The radar’s design is scalable to support the requirements of the US Air Force, Navy, Marine Corps, and National Guard for routine access to the NAS, and can also enable first responders and civil operators to safely pilot UAVs in public service operations.
