ADU-11e

project about to be finalized, shown in Beppu Japan

The ADU-11e (Analog Digital Unit) is a HF logger with 8 channels and 131 kHz max. continuous sample rate on 6 channels (1024 Hz lowest).
The system has a single mainboard with all channels integrated and soldered GPS (GPS, Glonass, BeiDou, Galileo). The CPU is an ARM quad core 64bit.

One of the design aims is to keep the system small and light weight for airborne applications (250 g board and 250 g connectors).
The channel configuration shall be 2xE and 6xH sampled.
3 H channels can be connected to a SHFT-02e or SHFT-03e and the other 3 H channels to a FGS-04e type fluxgate (airborne)
GPS data will be written @0.1Hz for control.
For ground based you connect coils like MFS-06e or MFS-07e and electric field. For extended LF recordings with 6 magnetic fields, use the ADU-12e

  • < 4 W power consumption

  • 8 channels 24 bit ADC

  • weight including casing: 4.8 kg

  • Dimensions: WxHxD 33 cm x 12cm x 25 cm

  • ~ 64 Hz yaw, pitch, roll sampling for SHFT-02e, SHFT-03e and FGS-04e

  • simultaneous recording of AMT & MT with dedicated sensors

  • continuous streaming of atss data for remote logging

The systems writes standard ats files as well as streamed double data atss (Matlab, Python/Julia NumPy array compatible with JSON data header)

You can use syncthing, rsync and WebDAV to transfer data to your office.
