Flight-control hardware has been upgraded on board, and Sentinel inherits key capabilities from the BMR2 family: it can support GPS and ground-referenced imaging modules to enable fully autonomous missions. With an encrypted, frequency-hopping C2 datalink, it maintains reliable communications even in high electromagnetic-interference environments.

In coordinated operations with the BMR2, Sentinel is designed for mesh networking; its compact size and autonomy allow it to act as a rapidly deployable airborne relay, extending the BMR2 C2 datalink.
