The voice communication and control system (urgencies) combines all modern and standard communications into a single, secure and reliable system for significant improvement of operational efficiency. Modular hardware and decentralized software create flexibility in implementation.The investment is strictly defined according to the required capacity with options for its expansion.This minimizes the ubiquity and operating costs by directing investments to the specific application and system requirements. It is designed based on years of experience in the defense industry. The architecture of the system is built on the principles of security, failure resistance and reliability.Using repeatable hardware, end-to-end encryption, and decentralized software, Apostille ensures reliable coordination between forces on all available standard and modern communications.
