Authenticating a mobile user device with a mobile network operator in advance of an MNO authentication request from the mobile user device can be done by a satellite network sending an authentication request to the MNO system, obtaining a set of authentication vectors related to the mobile user device, storing them into a proxy home location register, receiving the MNO authentication request from the mobile user device, generating an authentication request response based on the authentication vectors, sending the authentication request response to the mobile user device, receiving an authentication response including a received signed response, comparing the received signed response with the stored signed response, and if the received signed response and stored signed response match, deem that to be a successful authentication, add an MNO location update message to a request queue and forward the MNO location update message to the MNO system over the channel when available.

Technology for a cellular signal booster with a satellite location system signal rebroadcast functionality is disclosed. The cellular signal booster can identify a satellite location system signal received via a satellite location system module of the cellular signal booster. The cellular signal booster can provide the satellite location system signal to a signal path for amplification of the satellite location system signal. The cellular signal booster can broadcast an amplified satellite location system signal to a mobile device within a defined distance from the cellular signal booster.

The terrestrial-based satellite telephone monitoring system may be used for, among other things, intelligence gathering purposes that intercept communications to or from target satellite handsets or terminals. The exemplary signal processing units receive wireless signals and extend the line-of-sight range of a terrestrial-based satellite telephone monitoring system. The exemplary signal processing unit may be installed in or on an aerial vehicle, such as an unmanned aerial vehicle (UAV), or a satellite, such as a CubeSat, or other vehicle

The method of authenticating the source of a communication is disclosed. The method includes executing a clock for an operation period. The method also includes receiving a communication from a remote device at a communication time corresponding to a time interval of a plurality of time intervals sequentially covering the operation period. Each time interval has an associated authentication value. The communication includes a commitment value. The method also includes determining whether the commitment value matches the authentication value associated with the time interval corresponding to the communication time. The method also includes processing the communication when the commitment value matches the authentication value associated with the time interval corresponding to the communication time. The authentication value associated with the time interval corresponding to the communication time includes a hash digest of a hash function applied to the authentication value associated with a sequentially subsequent time interval.

Systems, methods, and apparatus for satellite operations with secure enclave for secure inband hosted payload operations are disclosed. In one or more embodiments, a method for payload operations comprises receiving, by a vehicle, host commands from a satellite operation portion of a host spacecraft operations center (SOC). The method further comprises reconfiguring a payload and at least bus component on the vehicle according to the host commands. Also, the method comprises transmitting, by the vehicle, host telemetry to the satellite operation portion of the host SOC. In addition, the method comprises receiving, by the vehicle, hosted commands from a secure enclave of the host SOC. Additionally, the method comprises reconfiguring the payload on the vehicle according to the hosted commands. Further, the method comprises transmitting, by a payload antenna on the vehicle, host payload data, hosted payload data, and the encrypted hosted telemetry to the secure enclave.

An electronic user device includes inclusion list storage with electronically readable memory, for storing an inclusion list and the inclusion list indicating included logical IDs. The device also has a security module app that receives a cellular broadcast message and extracts logical IDs therefrom. This processes a targeted cellular broadcast message embedded in the payload of the cellular broadcast message, based on whether a logical ID, also embedded in the payload, of the targeted cellular broadcast message is on the inclusion list. It then formats it for consumption by an electronic user device app that receives data via a data channel when available.

A wireless telecommunications apparatus for use with a non-terrestrial wireless telecommunications network, the wireless telecommunications apparatus comprising circuitry configured to: receive first information associated with a satellite of the non-terrestrial wireless telecommunications network, the first information comprising incomplete ephemeris information of the satellite; transmit a signal usable by a second wireless telecommunications apparatus to verify a location of the wireless telecommunications apparatus relative to the satellite; and receive second information associated with the satellite, the second information being usable by the wireless telecommunications apparatus to determine complete ephemeris information of the satellite.

Systems and techniques are provided for wireless communications performed at a network entity. For example, the systems and techniques can include obtaining, at the network entity, a target relative time difference (RTD). A transmission timing pre-compensation can be determined at the network entity between a first reference signal and a second reference signal, wherein the transmission timing pre-compensation is determined based on the target RTD and one or more network delay components. The first reference signal and the second reference signal can be transmitted using the transmission timing pre-compensation to offset the first reference signal from the second reference signal by the target RTD.
