The QRF-4500-BC™ combines long-range 1550 nm laser ranging, ballistic computation, GPS, digital compass, and environmental sensing into a compact weapon-mounted fire-control system. Rather than requiring operators to combine separate rangefinding, ballistic, and environmental equipment, the QRF-4500-BC provides the data required to rapidly generate an actionable firing solution at the weapon. Its eye-safe laser, integrated ballistic library, rugged construction, and recoil-resistant design support demanding applications from individual weapons through heavier-caliber platforms.

Beyond its operational capability, the QRF-4500-BC provides a rapidly available, Canadian-made and ITAR-free alternative for users seeking to field or supplement existing fire-control capabilities without relying exclusively on US-controlled supply chains. As an OEM, GSCI can support configuration, production, and sustainment directly, providing a scalable solution for programs requiring responsive delivery and long-term availability.  The system addresses the equipment and decision burden associated with obtaining range, environmental data, orientation, and ballistic calculations from multiple separate devices. It also provides an alternative procurement pathway for organizations requiring rapid access to a mature, production-ready fire-control capability without dependence on US-controlled sourcing, at a more competitive/flexible price point.

The Inertial Labs RMCU utilizes three 3-axes, each precision MEMS accelerometer, miniature Fluxgate magnetometers, and MEMS gyroscopes, to provide accurate heading, pitch, and roll of the device under the measure. The integration of gyroscopes’ output provides high-frequency, real-time measurement of the device rotation for all three rotational axes. Accelerometers and Fluxgate magnetometers measure absolute and very accurately in static and dynamic conditions, such as pitch, roll, and heading/Azimuth at RMCU initial alignment, and provide ongoing corrections to gyroscopes during operation.

These devices utilize advanced, tactical-grade MEMS sensitivity whose size, power consumption, reliability, and performance are ideal for accomplishing complex tasks requiring accurately stabilizing assorted platforms. The TAG units are factory-calibrated over their operational temperature range and precision machined to ensure low non-orthogonality and misalignment between sensitive elements. Additionally, these items are ITAR-free and exportable (ECCN 7A994) to available countries. Each unit is supplied with individual Calibration and Acceptance Test Certificates and goes through extensive Quality Assurance and Quality Compliance procedures to ensure product reliability before shipping.
