ARTEX has introduced a 406MHz approved transport-grade alkaline battery-powered emergency locator transmitter (ELT) called the ELT 4000, the company announced on 26 February.
ARTEX ELT 4000 features an alternative power source to traditional lithium batteries that is exempt from FAA special conditions. It uses a five-year replaceable alkaline battery and does not require additional protective housing or containment vessel.
The ELT 4000 is suitable for simplified forward fit and retrofit opportunities. It is a one-piece solution featuring built-in NAV interface (ARINC 429), allowing for connection to onboard GPS. As it is a single output ELT, the ARTEX device uses the same RF output and only one coax cable to transmit both 406MHz and 121.5MHz signals. It also features options including a two-wire remote switch that does not require any aircraft power.
The ARTEX ELT 4000 has received Cospas-Sarsat and FAA Technical Standard Orders certification. Activated manually using cockpit remote switch or automatically via internal G-Switch, the 406MHz signal is transmitted to the Global Cospas-Sarsat satellite network and routed to the nearest search and rescue agency. GPS data embedded within the digital transmission reduces the search radius to 100 metres.
The ELT 4000 is also approved and available in a helicopter model with a 5-axis G-Switch.
The airborne three-domain, the two ground-based and the ¼ ATR OpenVPX-based cross-domain systems were engineered to provide real-time security across multi-domain operations.
DARPA’s Mission-Integrated Network Control (MINC) programme was set up to develop an autonomous tactical network and enable critical data flow in contested environments.
Why space is an essential part of modern military capabilities
Defence-secure mixed reality headsets can save hours, or even weeks, of travel time to fix defunct equipment or get subject experts effectively “on-site” where they are needed.
The Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) counter-improvised explosive device (C-IED) and Drone Restricted Access Using Known Electromagnetic Warfare (DRAKE) counter-UAS (CUAS) systems are mounted and dismounted RF jammers.
