摘要： A UE may include IoT NTN device, and the UE may acquire the GNSS location to perform the time/frequency pre-compensation. A NAS layer of the UE may initiate a connection request procedure based on the GNSS fix procedure at one or more lower layer of the UE. A network may transmit a paging request to the UE, and manage a paging response timer based on the GNSS fix procedure at the UE.

摘要： Machine learning techniques can be used to mitigate multipath in a GNSS receiver that includes a first trained model that provides extra path length (EPL) corrections in the GNSS receiver. The first trained model can be updated using an updated and trained model from one or more assistance servers that are in communication with the GNSS receiver. The GNSS receiver can provide, for a particular computed position and time, extracted features from received GNSS signals to the one or more assistance servers. The assistance servers can then use the extracted features and a source of true EPL corrections (e.g., from a 3D building map database for the particular computed position and time) to train a server model. The server model, once trained to a desired level of accuracy, can be transmitted to the GNSS receiver to replace the first trained model. The server model can be compared to the first trained model to verify it can provide more accurate EPL corrections than the first trained model. The server model and the source of true EPL corrections can be specific for a geographic region, so different regions have different server models based on the corresponding sources of true EPL corrections.

摘要： A communication device is attached to an animal in a facility, for example, using a band. The communication device transmits at least a position of the communication device (hereinafter referred to as position information) and identification information of the communication device (hereinafter referred to as a communication device ID) to a position information transmission device. The position information transmission device uses the position information and the identification information received from the communication device to select an animal whose position information is to be delivered. The position information transmission device transmits the position information about the selected animal to at least one of an in-zoo display device, a user terminal, and a staff member terminal.

摘要： Improvements in Global Navigation Satellite System (GNSS) spoofing detection of a vehicle are disclosed utilizing bearing and/or range measurements acquired independently from GNSS technology. Bearing and/or range measurements are determined from a GNSS-calculated position. Additionally, bearing and/or range measurements are acquired from an independent sensor, such as a Very high frequency Omnidirectional Range (VOR) receiver and/or a Distance Measurement Equipment (DME) receiver. The differences between the GNSS-based bearing and/or range and the bearing and/or range determined from the independent sensor, along with any applicable sources of error or uncertainty (including the post-hoc residuals from the GNSS-calculated position), are input into an analytical algorithm (e.g., RAIM) to determine whether GNSS spoofing is present with respect to the calculated GNSS position. If spoofing is detected, an alternative position determining system can be used in lieu of GNSS technology, and alerts can be sent notifying appropriate entities of the spoofing result.

摘要： An information processing system includes a server and a first vehicle acquiring a combination of first and second position information of the first vehicle. The first position information is calculated using a positioning signal from the first satellite system. The second position information is obtained by correcting an error of the first position information using a positioning reinforcement signal from the second satellite system. The first vehicle or the server calculates difference information between the first and second position information for each combination thereof. The server estimates a calculation accuracy for the first position information in a road section on a road map based on one or more pieces of difference information in which one or more positions indicated by the second position information corresponding to the difference information are within the road section and to output the calculation accuracy for the first position information in the road section.

摘要： A method for a user equipment (UE) in a non-terrestrial network (NTN) is provided. The method receives, from a base station (BS), an indication associated with a UE-specific timing advance (TA) report. The indication includes a value. The method initiates a random access (RA) procedure. The method then determines whether to transmit the UE-specific TA report based on the value of the indication. If the method determines that the value enables transmission of the UE-specific TA report, the method transmits, to the BS, the UE-specific TA report through the RA procedure.

摘要： In a positioning system configured to perform positioning using N mobile terminals, where N is an integer of two or greater, each of the mobile terminals includes a positioning device, a communication device configured to exchange information with another mobile terminal using wireless communication, and a battery configured to supply power to the positioning device and the communication device. Each of first mobile terminals that are some of the mobile terminals activates the positioning device to perform positioning of a first current position, and a second mobile terminal other than the first mobile terminals reduces at least power to be used by the positioning device, and uses information of the first current position positioned by the first mobile terminal, and the information exchanged with the first mobile terminal by the communication device to perform positioning of a second current position.
