Researchers at the Moscow Institute of Physics and Technology (MIPT) have developed a navigation method that determines the coordinates of moving objects using mobile network signals. This approach relies on standard measurements from mobile terminals, such as smartphones or modems, to track position without relying on satellite systems.
The technology utilizes the Reference Signal Received Power (RSRP) parameter, which measures the signal strength from base stations. By continuously analyzing these signals, the system builds a radio wave propagation model. The method functions even without an active SIM card, leveraging existing telecommunications infrastructure.
Experimental tests conducted with a modem mounted on a vehicle demonstrated that the system achieves positioning accuracy ranging from 3 to 20 meters. The algorithm processes RSRP values from multiple fixed base stations with known coordinates, automatically filtering out anomalous data and unstable signal sources to calculate the most probable location.
The developers suggest this technology could serve as a primary or supplementary navigation tool in urban areas, industrial zones, or indoors where satellite signals are often weak or unavailable. Potential applications include tracking railway transport, long-haul trucks, autonomous freight vehicles, and heavy machinery in mining operations.
Currently, the MIPT team is discussing the pilot implementation of this software and hardware platform to test its performance in industrial environments.
