One of the important issues being explored in Industry 4.0 is collaborative mobile robots. This collaboration requires precise navigation systems, especially indoor navigation systems where GNSS (Global Navigation Satellite System) cannot be used. To enable the precise localization of robots, different variations of navigation systems are being developed, mainly based on trilateration and triangulation methods. Triangulation systems are distinguished by the fact that they allow for the precise determination of an object’s orientation, which is important for mobile robots. An important feature of positioning systems is the frequency of position updates based on measurements. For most systems, it is 10–20 Hz. In our work, we propose a high-speed 50 Hz positioning system based on the triangulation method with infrared transmitters and receivers. In addition, our system is completely static, i.e., it has no moving/rotating measurement sensors, which makes it more resistant to disturbances (caused by vibrations, wear and tear of components, etc.). In this paper, we describe the principle of the system as well as its design. Finally, we present tests of the built system, which show a beacon bearing accuracy of Δφ = 0.51°, which corresponds to a positioning accuracy of ΔR = 6.55 cm, with a position update frequency of fupdate = 50 Hz.

“…In particular, [11] shows how to perform carrier phase tracking for positioning with orthogonal frequency-division multiplexing (OFDM) signals from time and frequency synchronized BSs, considering aspects of multipath and phase wrapping, while [12] shows that CPP in FR1 provides sub-meter accuracies for both static and dynamic users. The use of reference stations, common in GNSS RTK, was also explored for 5G positioning [6], [15]. CPP has also been combined with various MIMO configurations, such as massive MIMO [16] for tracking phase information from multipath components, cell-free MIMO [13] for evaluating the impact of dense multipath, and near-field tracking [17].…”

The carrier phase of cellular signals can be utilized for highly accurate positioning, with the potential for ordersof-magnitude performance improvements compared to standard time-difference-of-arrival positioning. Due to the integer ambiguities, standard performance evaluation tools such as the Cramér-Rao bound (CRB) are overly optimistic. In this paper, a new performance bound, called the mixed-integer CRB (MICRB) is introduced that explicitly accounts for this integer ambiguity. While computationally more complex than the standard CRB, the MICRB can accurately predict positioning performance, as verified by numerical simulations, and hence it serves as an useful guide to choose the system parameters that facilitate carrier phase positioning.
