Close Air Solutions – IZLID

Close Air Solutions (CAS) is a Bristol based company situated at the acclaimed Bristol and Bath Science Park that design and produce simulation equipment used for training defence and security personnel. CAS provide a vast array of simulation applications, which include software applications and the integration of replica military equipment providing the trainees with the most realistic and lifelike training environment.

Close Air - IZLID

Close Air Solutions approached Cubik Innovation to design and develop the IZLID training simulator in conjunction with other simulation devices developed by CAS.

In the field an IZLID is a compact, lightweight infrared laser pointing and marking device used by the military. It is designed to be used as a command pointer, for target marking and for communicating with aircraft. The IZLID is small enough to fit in a user’s pocket or attach to their belt for quick access, offering swift guidance to ground personnel over a range of 39km.

Cubik’s scope was to replicate the look and feel of an IZLID in its aesthetics, ergonomics and user functions minus the real world infrared beam.

The IZLID simulator connects to the Close Air Solutions simulator system via a single USB lead and sends back data regarding movement.

Using the IZLID physically, the operator points the IZLID at the display during training scenarios and the beam is generated in sync with the position of the IZILID in the real world. The allows the operator to gain an understanding of how the IZILID behaves and reacts.

CAS sought a small batch run of units in order to develop their simulator and for sale to their simulator owners.

Cubik were responsible for the electronic design (carried out in Altium designer), the enclosure design (carried out in Solidworks) and embedded software.

As the quantity was too low to allow cost effective injection moulding, the housing was produced in a short run using Vacuum casting methods. On completion of the embedded software, a short run of units was built using our in-house production facility.

Maintaining a close working relationship with the CAS Team not only allowed for excellent communication, but also the opportunity to collaborate in the development of the product, ensuring the end result replicated the real wold product.

Adrian Schmieder of HiETA commented: “Cubik’s quick turn-around of a functioning PCB has sped the delivery of the project and enabled me to focus on areas of the project in which HiETA has expertise.  The project is a great success and produced valuable information even from its first use.  I am very impressed with the support Cubik provided me throughout the project, from initial concept through to PCB delivery.  I will not hesitate to engage with them again as future PCB projects arise.”


Speaking about the collaboration between Inductosense and Cubik Innovation, Founder and CTO Dr Chenghuan Zhong (Bamboo) stated: "It was great working with the knowledgeable and experienced team at Cubik Innovation. They always provide full support as well as useful and thoughtful advice to us, helping us find solutions for really difficult problems."


Geoff Jones, Aquabar Inventor: "It was a pleasure to work with Cubik on our project. Paul and Sam understood the concept at one meeting, and produced a solution filling the brief within two weeks which has enabled us to find a potential partner. We will certainly use Cubik for our production units later in the year, Many thanks."

Paul Davey, Associate Professor (SL) Plymouth University: "If you need a prototype developed to a high standard and on time you would be hard pushed to find someone better. They have highly trained, experienced engineers who get the job done."

Clean Energy Prospector Ltd

Damon Rand, Head Product Design: "Paul and the team have really helped us speed up the turnaround on our prototypes and assure the manufacturability of our designs. If you’re designing electronics in the South-West, then Cubik is a great choice for short-run manufacturing."
