Northrop Grumman's Amherst Systems business unit has delivered a combat electromagnetic environment simulator (CEESIM) for Gripen JAS 39 multirole fighter, developed by Saab.

The advanced technology simulator will be used to perform aircraft testing on the multirole fighter.

Northrop Grumman Amherst Systems site director Joe Downie said: “This delivery represents the continuation of a long-standing relationship with Saab and confirms our dedication to the success of their mission.”

The CEESIM system offers advanced pulse generation (APG) capability, which uses the latest digital technology to generate advanced waveforms.

The simulator is also capable of performing digital modelling of multiple active electronically scanned array (AESA) antennas.

When coupled with CEESIM’s angle-of-arrival modelling and controlled by a graphical user interface, the system is immediately transformed into the most powerful, advanced simulator available, Northrop stated.

Downie added: “CEESIM’s high-speed direct digital synthesiser technology brings significant advantages to Saab, including higher modulation sample rates, wide bandwidth precision intrapulse modulation, higher frequency resolution and accuracy, and reduced calibration time.

“The APG utilises a modular design for improved maintainability.

"All of this leads to lower cost and increased system reliability.”

"This delivery represents the continuation of a long-standing relationship with Saab and confirms our dedication to the success of their mission."

Additionally, the CEESIM is said to provide radio frequency simulation of multiple, simultaneous emitters and static/dynamic platform attributes that are required to simulate true-to-war conditions.

Equipped with up to 8,192 instantaneous emitters and platforms, the system offers unmatched signal fidelity, according to the company.

The Gripen multi-role fighter aircraft has been designed to perform an extensive range of air-to-air, air-to-surface and reconnaissance missions, by employing modern range of weapons.
