Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless communications device detects a trigger to communicate via non-terrestrial network (NTN) connectivity, determines whether one or more obstructions are estimated to be blocking a subset of NTN space vehicles of a set of NTN space vehicles expected to be in view of the wireless communications device at a current location of the wireless communications device, and transmits, in response to a determination that the one or more obstructions are estimated to be blocking the subset of NTN space vehicles, at least one message towards at least one NTN space vehicle of the set of NTN space vehicles other than the subset of NTN space vehicles.

Abstract: Described are methods, systems, and devices for correcting ionospheric error. In some aspects, a mobile device equipped with a Global Navigation Satellite System (GNSS) receiver is configured to determine a positioning measurement of a GNSS signal. The mobile device is further configured to receive augmentation data from an augmentation system. When the mobile device is unable to obtain newer augmentation data, the mobile device can instead obtain augmentation data associated with historical Total Electron Content (TEC) values. In such instances, the augmentation data will have been generated to represent ionospheric delay during a time period that ended before the augmentation data is obtained. Based on the augmentation data associated with historical TEC values and a pierce point of the received GNSS signal, an ionospheric error in the positioning measurement of the GNSS signal can be determined and corrected.

Abstract: In some implementations, a device may obtain historical orbital data indicative of orbital movement of a set of satellites over a period of time, the set of satellites comprising at least a subset of satellites of the satellite constellation. The device may, for each satellite in the set of satellites, estimate a set of orbital parameter values by fitting an orbital model to the historical data of the respective satellite, wherein at least one orbital parameter value of the set of orbital values is common across a group of satellites within the set of satellites. The device may send assistance data to at least one mobile device, the assistance data indicative of the respective set of orbital parameter values for all satellites of the set of satellites.

Abstract: A method, apparatus, and system are disclosed for providing modified orbital assistance data to a mobile station to determine its location using global navigation satellite system (GNSS). In some example embodiments, a method for determining a location of a mobile station using orbital assistance data may include: receiving satellite positioning signals from a plurality of GNSS satellites; receiving orbital assistance data comprising a distance between a location on an antenna which is associated with a first frequency of the satellite positioning signals and a location on the antenna which is associated with a second frequency of the satellite positioning signals; and determining the location of the mobile station based on the orbital assistance data and the satellite positioning signals.

Abstract: Described are methods, systems, and devices for correcting ionospheric error. In some aspects, a mobile device equipped with a Global Navigation Satellite System (GNSS) receiver is configured to determine a positioning measurement of a GNSS signal. The mobile device is further configured to receive augmentation data from an augmentation system. When augmentation data for a current measurement period is unavailable, the mobile device can obtain augmentation data associated with Total Electron Content (TEC) values (e.g., vertical TEC values) during one or more prior measurement periods. Based on the augmentation data associated with TEC values during one or more prior measurement periods and a pierce point of the received GNSS signal, an ionospheric error in the positioning measurement of the GNSS signal can be determined and corrected.

Abstract: In an aspect, a user equipment (UE) determines a target orientation associated with the UE for a two-way satellite communication session that provides a line of sight (LOS) alignment between an antenna of the UE with a satellite antenna, determines a current orientation associated with the UE, determines difference information associated with a difference between the current orientation of the UE and the target orientation of the UE; and transmits, to a user feedback component, an instruction to provide user feedback that is based on the difference information and that comprises non-visual user feedback or visual feedback that is separate from a display screen of the UE.

Abstract: In some implementations, a method of facilitating pointing of a mobile device at a satellite of a satellite constellation for satellite-based data communication, may comprise obtaining, at a first time point, historical orbital data indicative of orbital movement of a plurality of satellites of a satellite constellation over a period of time. The method may also comprise assigning a reference orbital dataset of the plurality orbital datasets determined at a reference time point to corresponding control boxes of a reference grid covering the satellite constellation, wherein each control box of the reference grid corresponds to a satellite of the satellite constellation. The method may also comprise mapping the plurality orbital datasets to the reference grid for an orbital model based on the assignment of the reference orbital dataset.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a non- terrestrial network (NTN)-capable user equipment (UE) determines to perform at least one NTN transmission to an NTN station, and transmits information associated with the at least one NTN transmission to one or more one or more global navigation satellite system (GNSS)-capable UEs via at least one peer-to-peer (P2P) channel. The NTN-capable UE performs the at least one NTN transmission. At least one of the GNSS-capable UEs receives the information, and performs one or more GNSS position measurements based on the information so as not to overlap with the at least one NTN transmission in a time domain, a frequency domain, or both.
