Compact INS & GPSDome
Specifications:
Performance Comparison:
Honeywell's alternative navigation suite for UAVs combines the Compact Inertial Navigation System with the GPSdome anti-jammer to ensure reliable drone navigation during GNSS outages, in environments such as urban canyons, and during deliberate attacks such as GPS jamming and spoofing.
The tactical-grade Compact INS provides highly accurate navigation in a low-SWaP package, enabling safe operations for a wide variety of drone platforms. Accuracy can be refined down to centimeter-level with RTK corrections received via a 4G LTE modem.
The Compact INS can be seamlessly integrated with the Pixhawk 2.1 Cube autopilot line as well as the ArduPilot Mission Planner GUI.
