Profiling floats and gliders
Deployed once, rarely recovered. The battery sets the mission length.

Argo floats replaced each year, at about $40,000 each.
Argo Program
Profiling floats dive and surface on their own for years, until their batteries run out. Gliders fly for months between recoveries. Every extra month of good data counts.
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
Power runs down
Batteries fade and panels foul. The system has to do less, on purpose, and keep the important part going.
02
Computers fail one by one
Radiation, heat and age take out processors and memory. Nothing is replaced until the next visit.
03
The link is thin
Bytes per message, or nothing until the next window. Problems have to be solved on site.
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
Three computers vote. One bad result is outvoted.
2 alive · compare
Two compare. A known-answer test finds the faulty one.
1 alive · self-check
The last one checks its own work and keeps profiling until the battery ends, 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.
Floats are rarely recovered. Why does decay matter?
Because the last months still produce data. Mru keeps checking results as processors and memory fail, so that data stays trustworthy.
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.
