Parvus DuraNET 20-11 Ultra-Small Form Factor (USFF) Gb Ethernet switch: weighing 0.50 pounds, the DuraNET 20-11 consumes under 8 watts of power. It provides a level 2+ management feature that includes support for IEEE-1588v2 Precision Timing Protocol (PTP). The DuraNET 20-11 is a line replaceable unit (LRU) designed to meet MIL-STD-704F, MIL-STD-1275D, MIL-STD-461F, and RTCA/DO-160 for civil and military use. The subsystem is sealed with no moving parts and supports temperature operations ranging from -40 ºC to +85 ºC. It is resistant to shock, vibration, humidity, altitude, dust, and water ingress.

Parvus DuraMAR 5915 Rugged IP Router: This LRU integrates Cisco’s 5915 embedded services router (ESR) card in a rugged chassis for unmanned vehicle installations. It can be used for IP networking technology and situational awareness applications. The DuraMAR has dual WAN uplinks and comes either as a 5-port network router or with an integrated Gb Ethernet switch for a total of 19 Ethernet ports.

Parvus DuraCOR 80-40 Rugged Mission Computer: A COTS mission computer LRU subsystems, the DuraCOR 80-40 is based on the 2nd Gen Intel Core i7 processor with stackable PCI-Express bus (PCIe/104) architecture for I/O card expansion. It is designed for SWaP UAV applications combining graphics and multi-core processing. The DuraCOR 80-40 delivers environmental and EMI performance per MIL-STD-810G and MIL-STD-461F.
MPMC-9351 3U 5-slot Mission Computer: the MMPMC-9351 accommodates the power 3U cards within a 5-slot forced-air enclosure. The installed circuit cards in the system are isolated from environmental conditions. The system was designed to meet DO-160F Environmental Conditions for Airborne Equipment.

Data Transport System (DTS): The DTS Network Attached Storage (NAS) system is a SWaP network file server that supports storage protocols (NFS, CIFS, HTTP and FTP) through four 1 Gb Ethernet ports. It also has PXE protocol support. DTS system offers AES256 encryption to protect critical data-at-rest. It has three removable memory cartridges (RMC) that can store video, audio, and mission data. The record features can act as a sniffer for mission analysis by WireShark.
Acra KAM-500 Data Acquisition System: the Acra KAM-500 is an airborne data acquisition unit (DAU) that brings the COTS design approach to UAV Flight Test, Structural Health and Flight Data Monitoring applications. Hardwired finite state machines drive the DAU. The KAM-500 reduces cost and its design allows for installation in restricted spaces as well as for reducing weight on unmanned vehicles.
