Rohde & Schwarz had four patents in internet of things during Q2 2024. Rohde & Schwarz GmbH & Co KG filed a patent for a terrestrial positioning system that includes a mobile terrestrial transmitter with a local clock source and an inertial measurement unit, and a synchronization master with stored positioning information. The transmitter determines altered positioning information using the IMU and broadcasts a positioning signal with a timestamp. The synchronization master calculates expected time of flight based on the altered and stored positioning information to adjust the broadcast timing of the positioning signal.

Application: Terrestrial positioning system and method for improved terrestrial positioning (Patent ID: US20240192386A1)
The patent by Rohde & Schwarz GmbH & Co KG describes a terrestrial positioning system that involves mobile terrestrial transmitters with local clock sources and inertial measurement units, along with a synchronization master storing initial positioning information. The terrestrial transmitters broadcast positioning signals with timestamps, allowing the synchronization master to calculate expected time of flight, determine deviations, and instruct the transmitters to adjust broadcast timing accordingly. This system aims to enhance terrestrial positioning accuracy by utilizing IMUs and synchronization feedback to optimize signal transmission.
The system includes multiple mobile terrestrial transmitters mounted on land-based platforms, each broadcasting positioning signals with timestamps derived from local clock sources and altered positioning information determined by IMUs. The synchronization master stores initial positioning data for each transmitter, calculates expected time of flight, and provides feedback to adjust broadcast timing based on deviations. By enabling trilateration through delayed or preponed signals, this method improves terrestrial positioning accuracy and efficiency, particularly when utilizing FeMBMS or NB-IoT signals. Overall, the patent outlines a comprehensive approach to enhancing terrestrial positioning through synchronized adjustments based on IMU data and feedback mechanisms.
