NeuroPulse: command links that keep working when a link fails.

RecoupIQ is a software company. Our main product is company risk checks built on UK public records. NeuroPulse is our second line of work: software that keeps uncrewed aircraft, boats and remote sensors in contact over satellite, long-range radio and mobile links that are narrow, delayed and unreliable.

01What NeuroPulse does

Several links in one session. Commands go on every link at once, so losing one link does not stop control. Other data moves to a working link, and each change is logged.
Commands that cannot be forged or replayed. Every message carries a tag made with the device’s key. Forged, replayed and out-of-date messages are refused.
Fewer bytes on paid links. A low-traffic mode and compression reduce the data sent over satellite and narrowband links.
A record of each command link. It logs delay, interruptions and availability, for operators and test reports.

Works with the open autopilots PX4 and ArduPilot through MAVLink 2. Runs on computers as small as a Raspberry Pi.

21 / 21

flight-test steps completed in ArduPilot's flight software with the main link frozen for 8 s after take-off. A second link, 0.6 s slower, kept command.

Limit: Simulator and emulated links. With one link, the same test triggered the failsafe.

failsafes with the vehicle software on a Raspberry Pi 4 over Wi-Fi and the main link blocked for 8 s, in 3 runs.

Limit: Laboratory network. While the slower link carries the data, the ground sees the vehicle about 0.6 s late.

0 / 20

forged commands accepted. Plain MAVLink accepted all 20.

Limit: ArduPilot simulator. Equal to MAVLink 2 signing, with fewer bytes.

0 / 200,000

forged alarms accepted across a simulated fleet of 1,000 devices. Each alarm is 11 to 20 bytes.

Limit: Simulation. It does not prevent radio jamming.

1.5×

fewer bytes per hour than hard-tuned MAVLink in a hover: 191,500 against 296,500, on a satellite-like link.

Limit: Simulation. Its failsafe is slower: about 24 s, against 4.4 s.

88.6

buoy readings per 340-byte satellite message, against 28.4 for a standard compressor with a trained dictionary.

Limit: Recorded NOAA data. For one fixed reading, a hand-built binary format matches it.

~4 s

of speech per 340-byte satellite message, for short operational voice notes.

Limit: Clear but tiring to listen to; for short messages, not conversation.

300 / 300

Modbus exchanges correct through Serial Guard, which encrypts and authenticates legacy serial radio links (XChaCha20-Poly1305).

Limit: Raspberry Pi 4 with emulated serial ports. Not a certified security product.

03Where we are

These results come from our laboratory: flight-control simulators, emulated links and a Raspberry Pi. NeuroPulse has not yet flown on a real aircraft or used a live satellite link, and it is not certified aviation equipment.

Our next step is a field test with a partner. We work with operators and device makers who want a measured result on their own links. Alex Vasile, Founder · alex.v@recoup-iq.tech
