System and method for determining vehicle position by triangulation
A system and method for determining the location of a vehicle when GNSS signals are not available use triangulation between one or two radio transmitters and, respectively, two or one radio receivers mounted on the vehicle. The distance between each radio transmitter and/or each radio receiver can be determined according a phase difference between received radio signals. The radio signals can have the geographical location of the radio transmitter included therein. Utilizing the demodulated geographical location of each radio transmitter and the distance between the radio transmitter and each radio receiver, triangulation can be used to determine the geographical location of the vehicle.

A method, apparatus and computer readable medium are provided for determining position information of a receiver device. The method includes determining a plurality of beams and combining received multipath signals from the plurality of the beams. The received multipath signals are generated by a transmitter device.

Methods for measuring roll, pitch and yam angle and orientation misalignment in objects
A method for determining angular orientation of an object in two or more directions. The method includes: generating a scanning polarized RF source signal; receiving the scanning polarized RF source signal at one or more cavities of a sensor disposed on the object; measuring the scanning polarized RF source signal at a first portion of the sensor; reflecting the scanning polarized RF source signal toward a second portion of the sensor; measuring the scanning polarized RF source signal at the second portion of the sensor; and determining the angular orientation of the object in the two or more directions based on the measured signal at the first and second portions of the sensor.
SIM-based positioning
In various embodiments, techniques are provided for deploying a positioning applet to a SIM (e.g., a physical SIM card or an embedded SIM (eSIM)/integrated SIM (iSIM)) via an over-the-air (OTA) update or by permanent programming (i.e. “burning in”) during manufacture. The positioning applet may run solely on a processor of the SIM, functioning without support of application, OS or baseband software executing on the CPU or baseband processor of the UE, or network deployed infrastructure support. In operation, the positioning applet collects positioning measurements from a baseband processor (e.g., a baseband chipset) of the UE (e.g., via 3GPP protocols) which are sent (e.g., as an encrypted payload) to a remote location platform that compares the positioning measurements to known positioning data in a database (e.g., a crowd sourced database) to determine UE position. The remote location platform may provide an estimated position to a designated recipient system, without involvement of the UE.
