From requirements to a link
that holds.

The discipline that turns a mission need into a buildable subsystem. Meezak brings a satellite-systems-architecture background to the early, decisive phases of a programme — where the right trade-off saves a year of rework downstream.

• Requirements capture, system architecture, and interface definition
• RF link budgets, modulation and coding trade-offs, capacity analysis
• Phase A/B concept and feasibility study support for SATCOM payloads and terminals
• Independent review and verification of subsystem specifications

Electronically steered antennas are how a modern terminal tracks a moving satellite without moving parts — and how it rejects interference. Meezak works across the array, from element-level design to the beamforming that shapes the pattern in software.

• Active electronically steered array (AESA) architecture and trade studies
• Digital and hybrid beamforming design
• Adaptive nulling — steering pattern nulls onto interferers in real time
• Multi-beam and multi-orbit tracking concepts

A link is only as capable as the air interfaces it speaks. Meezak integrates across the established satellite standards and the emerging 5G non-terrestrial path.

• DVB-S2 / S2X forward link and DVB-RCS2 return link
• 5G-NR Non-Terrestrial Network (NTN) integration
• Modem selection, integration, and terminal-side signal processing
• Signal-processing integration on standard commercial modems

When positioning and timing can be jammed or spoofed, resilience is no longer optional. Meezak's research heritage is in exactly this problem: keeping the navigation solution trustworthy under deliberate interference.

• Interference detection and antenna-array nulling for GNSS
• Anti-spoofing techniques and signal-authenticity checks
• Robust position, navigation, and timing (PNT) for contested environments
• Resilience assessment of existing receiver and antenna chains
