# Satellite-linked remote devices

Small power budgets, links measured in bytes, nobody nearby.

32.5Mby 2029

Remote devices on satellite links, up from 5.8 million.

Berg Insight

Sensors on pipelines, farms, rivers and stations report over satellite links measured in bytes. When something goes wrong there, it has to be handled there.

Mru Field runs on the processors already in the equipment. When one fails and nobody can come, it continues on the ones left and delivers only results it can check. Status: decision core at TRL 3; first field pilot planned for 2027.

01

## The link is thin

Bytes per message, or nothing until the next window. Problems have to be solved on site.

02

## No one to ask

When two computers disagree, there is no operator to say which one is right.

03

## Power runs down

Batteries fade and panels foul. The system has to do less, on purpose, and keep the important part going.

## Three computers. Then two. Then one, still working.

Most redundant systems stop when they lose their majority. Mru Field steps down instead, and says which mode it is in.

3 alive · vote

A B C

Three computers vote. One bad result is outvoted.

2 alive · compare

A B C

Two compare. A known-answer test finds the faulty one.

1 alive · self-check

A B C

The last one checks its own work and keeps sending checked results, at half speed.

## Questions

Does Mru Field need new hardware?

No. It is software for the processors you already deploy. It runs beside your control code and decides which computer to trust as parts fail.

Does it need a lot of bandwidth?

No. It decides on the device and sends results, not raw votes.

How do we start?

Use the form below. We first model your hardware and show what each redundancy design returns over its whole life. Then we plan a pilot on your own equipment.
