A system and method for positioning based on navigation systems. The method includes receiving a list of Street Level Stations (SLSs), conducting ranging measurements with each SLS identified within the received list, receiving a global position of the each SLS identified within the received list, and computing a position of a user device based on the ranging measurements and a position of the each SLS identified within the received list.

System and method for combined ranging and GNSS positioning

A system and method for determining accurate positions of stationary global navigation satellite system (GNSS) sensors are provided. The method comprises triggering collection of satellite measurements by each of at least a first stationary GNSS sensor and a second stationary GNSS sensor, wherein the satellite measurements are collected per epoch; determining a position of the first stationary GNSS sensor using the satellite measurements collected by the first stationary GNSS; and determining a position of the second stationary GNSS sensor using the satellite measurements collected by the second stationary GNSS and at least the determined position of the first stationary GNSS, wherein the first stationary GNSS sensor is deployed in the vicinity of the second GNSS sensor.

System and method for determining accurate positions of stationary global navigation satellite system sensors

A system and method for detecting cyber-attacks. The method includes receiving satellite data from at least one satellite orbiting at a location of a ground-level sensor. The satellite data is received from the ground-level sensor. The method also includes determining whether the received satellite data is valid, and upon determining that the received satellite data is invalid, extracting a list of GNSS devices in a region where the ground-level sensor is deployed, and alerting each GNSS device in the list of GNSS devices on a potential cyber-attack.

System and method for providing cyber security for satellite-based navigation systems

A system and method for providing navigation through an underground space. The method includes receiving ephemeris data of a plurality of satellites in orbit at a location of the underground space, determining a schedule of the plurality of satellites in orbit, obtaining location of a plurality of pseudolites within the underground space, and determining satellite parameters to configure each of the plurality of pseudolites. Satellite parameters are determined based on the obtained location of each pseudolites and the determined satellite schedule. Also, the satellite parameters include at least a signal modulation parameter and a broadcast data parameter. The method also includes configuring each of the plurality of pseudolites with the respective satellite parameters, and controlling the plurality of pseudolites to broadcast satellite signals based on the determined satellite parameters. The broadcasted satellite signals simulate locations of the plurality of satellites in orbit.
