MARS

Key Features and Capabilities

At the core of the MARS stack is the Pathfinder algorithm, which is responsible for precise distance estimation. This algorithm is essential for calculating accurate distance values between devices.

MARS supports the draft specification for Bluetooth® Channel Sounding (CS), a technology specifically designed for accurate proximity and navigation applications. This feature enables even more precise determination of distance and angle of arrival.

The MARS stack seamlessly integrates with various hardware platforms, expanding its applicability across a wide range of products. This flexibility makes MARS an ideal solution for developers looking to incorporate advanced localization technologies into their products.

MARS offers a powerful platform for companies aiming to develop innovative solutions in the field of precise positioning and navigation, especially in complex environments where traditional methods may fall short.

The MARS Pathfinder algorithm is the cutting-edge algorithm at the core of the Metirionic Advanced Ranging Stack (MARS). Engineered for exceptional precision, this innovative technology models radio wave propagation to accurately distinguish the direct signal path from the various multipath reflections that can occur in complex environments.

The result? Unmatched accuracy in distance estimation with minimal computational effort. The MARS Pathfinder empowers your applications with reliable and precise proximity and navigation capabilities, making it an essential tool for leveraging Bluetooth® Low Energy (BLE) technology in today’s connected world.

The new Bluetooth® Channel Sounding feature does not provide direct distance data but instead offers PCT (Phase Correction Term) data that contains In-Phase (I/Q) values. These raw data must be further processed by application developers and Bluetooth® integrators to derive accurate distance measurements. The Metirionic MARS algorithm plays a crucial role in this process. This algorithm is designed to precisely process the PCT data and calculate exact distances. By combining Channel Sounding with MARS, developers can create a customized solution for their applications that fully leverages the power of Bluetooth® technology and enables reliable distance measurement.
