Proteus Unity
The Proteus™ Unity Modem System is the only dual-use satellite modem proven to operate efficiently through rotor blades. This advanced Software-Defined Radio (SDR) system delivers resilient, safe, secure IP communications on all commonly-used frequency bands across land, naval and airborne platforms.



Greater Resilience
Resistant to rotor blade blocking and agnostic to blade size, number of blades, single or twin rotor platforms Uses hybrid Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum (DSSS) techniques Automatic link adaptation for rain fade, platform movement, satellite footprint variation Provides interference-free, through-rotor communications to helicopter satellite terminals

Increased Efficiency
Highly scalable, supporting up to 125 modems in a single network Automatically shares bandwidth to optimise satellite resources and cost-efficiency Suitable for fixed, land mobile, airborne and naval platforms Supports all commonly-used frequency bands to reduce equipment required in the field Hosts multiple waveforms for different uses with simple software upgrade, reducing through-life costs Designed for easy integration into modern IP-based networks, including support for QoS and advanced routing



Increased Security
All configuration and management interfaces are secured so the system cannot be maliciously re-configured or monitored All network control traffic is secured and protected from exploitation, including that for DAMA and ACSM Entire modem is designed against UK CESG CPA baseline standard Hardware security module is designed against NIST FIPS140-3 Level 2 standard, providing independent assurance

Safe Operation
Supports EMCON Silence Mode, allowing users to receive without transmitting Supports ESM Mode, enabling simultaneous operation of Electronic Support Measures and satellite communications equipment Eliminates the backscatter of RF into the aircraft cabin by not transmitting into a overhead blade and causing RF reflections



Easier to Deploy
No ITAR components, allowing export to most countries Standard sizes and installation requirements Easy to use with automated modem management Quickly re-plans network as requirements change and automatically disseminates into the field Seamless integration with IP networks, with standard interfaces and fully-featured integrated router and switch
