The NanoS2 acquisition system is the new most efficient flight test recorder, with an ultra-compact design, and an ease of changing acquisition modules.

The NanoS2 provide modularity and permit to stack twelve data acquisition modules by unit. A unit is constituted by a CPU/Controller module with a recording capacity (from 8 to 1TB) and a power supply module that can support twelve modules.

The NanoS2 is a data acquisition concentrator completed with recording system combined in the same device, with this device you can make all in one modular and compact solution where other solutions require two separated unit.

The NanoS is declined in two versions (NanoS and NanoS2), depending of type of connector desired and your installation constraint. A large types of acquisition modules can be Stacked on the NanoS2

The NanoS2 CPU module

There is equipped with a reliable internal time code source/Irig B or it can be coupled in option with GPS time code. The unit is also equipped with solid state disk available from 8 to 512 GB capacity which directly record data in IRIG 106 chapter10 format. The flow rate of 500 Mbits/second by unit allowing to collect and record a large type of data like Full HD video, with another types acquisition modules in same time. You have also the possibility to make a connection with a remote control unit who can be supplied and download by Gigabyte Ethernet connection or by USB connection the data acquired by the unit. The unit can be also Configured/Controlled by a remote control box or by a computer. An optional IRIG 106 chapter 4 telemetry output is also available in option, who permit to transmit all or a part (Selectable) of collected data in real time to a ground station.

The NanoS2 CPU module

Power supply module

The power supply modules was constituted by two electrical circuits and is conform to MIL-STD-704F One circuit DC-DC Converter card, and another one is Ultra capacitor circuit who protect Nanos² installation from power interruption about >100 millisecond. There is no battery and therefore no preventive maintenance for power down protection. These modules are also able to be powered by battery if aircraft power is not available.
Power supply module


The coupling with other slave units is operated by a serial fiber optical link or Ethernet Link. Total of 1000Mbps flow rate is available in this configuration, in a total synchronous mode by IEEE 1588 Ethernet Precision Time Protocol for Ethernet or by proprietary protocol for Fiber optical network . The advantage of slave unit, its to capture others sensors parameters from another aircraft location and reducing the wiring.

CPU Module of master unit multiplex the data from other units placed in different place of the aircraft. Slave units are extension of the master unit assured by sFPDP connection of 2.5 Gbits/s (Full Duplex fiber optical) or Ethernet connection, who assure a total synchronous acquisition, between units.
