project about to be finalized, shown in Beppu Japan
ADU-11e
The ADU-11e (Analog Digital Unit) is a HF logger with 8 channels and 131 kHz max. continuous sample rate on 6 channels and 65 kHz on all channels (1024 Hz lowest).
The system has a single mainboard with all channels integrated and soldered GPS (GPS, Glonass, BeiDou, Galileo).
The CPU can be a ARM quad core i.MX 64bit.

One of the design aims is to keep the system small and light weight for airborne applications.
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 or
coils like MFS-06e or MFS-07e ;
GPS data will be written @0.1Hz for control.
< 5 W power consumption
~ 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)
