IMT messages can also be sent using AT commands over serial, with data transfer packet size flexible from 25 to 100,000 bytes. | Position and other data reports at a set interval or on request from Cloudloop Device Manager. IMT messages cannot be sent using AT commands over serial. |
| APNT | Integrated Iridium PNT module | Integrated Iridium PNT module |
| Supported Messages | Position reports, alerts (geofence/power/tamper as configured), and additional operational payloads (size/rate profile configurable) | Position reports, alerts (geofence/power/tamper as configured) |
The NMEA 0183 model uses the shared RockBLOCK Pro command set. Browse the RockFLEET Assured AT command reference →
Physical​
The Above Deck Unit is the RockFLEET Assured antenna assembly. Below Deck Unit is the general term for equipment installed below deck; depending on the selected bundle, this can be the standalone Chart Plotter, the Chart Plotter in the Rapid Deploy case, or the Power Hub.
The supplied below-deck equipment depends on the selected bundle:
- Full bundle: a standalone Raymarine AXIOM® 9 Chart Plotter and a Power Hub.
- Rapid Deploy bundle: a Raymarine AXIOM® 9 Chart Plotter fitted inside an Explorer rugged case.
- NMEA 0183 or NMEA 2000 stand-alone bundle: a Power Hub for connection to compatible third-party equipment.

Dynamic position accuracy varies by latitude. Iridium satellites have closer spacing at higher latitudes, resulting in improved accuracy nearer the poles.
| Location | Latitude | Median Accuracy | 95th/97.5th Percentile |
|---|---|---|---|
| Norway | 69° N | 25m | <50m (95%) |
| Red Sea | 19° N | 42m | <200m (97.5%) |
