/ VN-310

The VN-310 is for applications requiring a highly accurate inertial navigation solution in both static and dynamic operating conditions, especially in environments with unreliable magnetic heading and good GNSS visibility. was designed. The VN-310 provides the ability to accurately estimate true heading (azimuth relative to true north) in both static and dynamic conditions without relying on magnetic sensors. This is achieved by utilizing GPS interferometry technology (RTK moving baseline technology) that measures the heading of a vehicle or platform without any assumptions about vehicle dynamics. This is a very important feature in applications that require accurate heading at startup or in situations where there is insufficient motion to perform dynamic alignment.

The VN-310 is available in two package options with a precision milled anodized aluminum enclosure designed to meet DO-160G standards. With dual I/O connectors, the VN-310 offers maximum flexibility for interfacing with external GNSS receivers and IMUs. Alternatively, the VN-310 is also available in a miniature board-mount option that delivers tactical-grade IMU performance in an ultra-small package, bringing unprecedented capabilities to SWaP-C constrained applications.
