Patria OPTIME is set up according to the customer’s requirements The specification of the Patria OPTIME solution begins with an assessment of the current state of the customer’s operating environment, equipment and sustainment solution as well as the requirements set for them. After a successful feasibility study, there will be a more thorough value proposal phase together with the customer. Patria OPTIME ensures the performance of different kinds of fleets in all conditions over their entire lifecycle.

The Integrated Weather Observation System (IWOS®) is the compact, wireless, rugged weather station that can be customized to any customers’ specific needs. This system can replace legacy weather stations that require hardline power or extensive infrastructure for permanent installation. It integrates up to eight environmental sensing modules with optional satellite communication in a package that fits into a single case and weighs less than 25 lb. In addition to its portability, performance, and professional-grade construction, the modular design of the IWOS lends itself to higher accuracy, higher availability, and a lower lifecycle cost thanks to its easily replaceable and serviceable modules.

It features IR plus RGBW color LEDs (red, green, blue, white), all housed under a high‑strength polycarbonate dome. It supports multi‑wireless synchronization via short‑range communication, GPS/RTC, and mesh relay—enabling simultaneous use of RGB LED + IR or RGB LED + white LED, with up to 42 pattern synchronizations (expandable to 252) using 256‑bit encrypted data. Runtime reaches up to 130 hours (LED 130 h / IR 125 h) on a single AA battery. Built to MIL‑STD‑810G and KC standards, it ensures drop, dust, sand, immersion, and temperature resistance. Manufactured in Korea with domestic service support.

Hyundai Rotem's UGV has adapted the top-notch autonomous driving technoolgies from Hyundai Motor Group, capable of search and reconnaissance missions as well as munition transport. Fielded in real operation after approval by the ROK Army in 2021, its technologies were also appreciated in major events such as National Armed Forces Day and Combined Joint Live Fire Exercise.

Developed in 2002 as a single-soldier, short-range, anti-tank weapon system, we continue to work with soldiers to provide the weaponry needed to succeed. Backed by nearly two decades of experience, the resurgence of the tank in battle validates our expertise in this field. It’s the same old story – and David still beats Goliath.

Digitally recorded distressed and alarmed birds, along with the sounds made by their natural predators are broadcast through high output weather-resistant speakers. This triggers a primal fear and flee response. Super easy installation figure makes the systern portable across crop and place Replaceable, customizable species specific bio- acoustic sound chip according to birds kinds and specific regions Effective Coverage: Up to 50m for one single direction, approximately 5,000 square meter Technology integrated operation system enables sound duration and interval to prevent habituation to the sounds Overcharge, over-discharge protection Sound Pressure: 120-130 db at 1 meter Frequency: 3-5 kHz With severe bird infestations, it is always recommended to use at least 2 bird control methods together. Sonic cannon is a very good to use in conjunction with the bio-acoustic bird repeller.
