Minifog is a advanced, precise, solid-state true north seeking compass that has no moving parts achieving an extremely fast start-up time. The system has a reliable performance far exceeding any traditional mechanical compass with an average time between failures of over 25000 hours.
The MiniFOG is a solid‑state subsea heading and attitude reference unit that delivers precise heading, roll and pitch measurements without moving parts. It is designed for use on ROVs, AUVs, and surface platforms in harsh marine environments.
The manual covers technical specifications, power requirements, environmental limits, dimensions, startup procedures, data interfaces (RS232/RS485, analog), and software options, helping users install, configure, and operate the device safely and efficiently. This manual is written in Chinese.
| Typical heading accuracy (static/dynamic) | 0.2" - 0.3" x tan(latitude) |
|---|---|
| Worst‑case heading accuracy | 0.7" x secant latitude |
| Roll & pitch typical accuracy | better than 0.02" |
| Startup time (typical) | 3‑5 minutes |
| Maximum operating depth | 1000 m SW |
| Power supply | 24 VDC @ 2.2 A max (also 110‑220 VAC) |
| Data interfaces | RS232/RS485, optional RS422, analog 0‑3.599 VDC |
The MiniFOG typically starts up in 3 to 5 minutes.
It requires a 24 VDC supply at up to 2.2 A, and can also be powered from 110‑220 VAC.
The unit is rated for a maximum depth of 1000 m seawater.
The MiniFOG provides RS232/RS485 serial ports (optional RS422) and an analog voltage output representing heading, roll and pitch.
