The TAC-440 is the world’s smallest 1°/hour tactical-grade IMU, with an ultra-compact package of less than 5 cubic inches and weighing just 0.5 lbs. Designed as a drop-in replacement for the Honeywell 1930 and 4930, the quartz MEMS IMU is ideal for mission-critical drone and robotics applications in challenging environments.
The rugged IMU features solid-state quartz sensors, electromagnetic interference (EMI) protection and hermetically-sealed construction, ensuring superior longevity and reliability under highly demanding conditions. The unit also provides continuous Built-in Test (BIT) capabilities and configurable communications protocols.
The TAC-440 supports four data message synchronization methods, and the user can select whether the synchronization pulse is internally generated and output as a Time of Validity (TOV) of the output data, or whether the internal software will identify the pulse input and synchronize the output data.
