Method for antenna beam and null steering under high platform dynamics
An electronically steerable antenna includes an embedded antenna processor and orientation sensor, separate from any orientation sensor within a corresponding GPS receiver. The orientation sensor tracks orientation changes in the mobile platform including the electronically steerable antenna, and an antenna processor updates beams and nulls produced by the antenna to track a real-world location based on the orientation changes. The embedded antenna processor periodically compares the orientation data from the embedded orientation sensor with orientation data from systems aboard the mobile platform to calibrate.
Time-domain waveform reporting for positioning
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may report measurements of a signal transmitted by a base station via a waveform. Based on the waveform, the base station may determine a position of the UE. The UE may measure the signal in a frequency band, where additional signaling in an adjacent frequency band causes interference on the signal. The UE may determine characteristics for measuring the signal based on the interference and may generate samples of the signal based on the measurement characteristics. Additionally, the UE may identify one or more antennas for measuring the signal and generate the samples based on the identified antennas. The UE may transmit the waveform report to the base station based on the samples. In some cases, the waveform may be based on a fractional symbol reporting scheme or a time mask with an offset and sampling rate.
APPARATUS, METHOD AND COMPUTER PROGRAM FOR BEAM MANAGEMENT
There is provided an apparatus, said apparatus comprising means for receiving an indication from a base station, at a user equipment having at least one antenna panel, to provide beam reporting information according to one of a plurality of beam reporting formats and providing beam reporting information to the base station according to the indicated beam reporting format.

SYSTEM AND METHOD FOR NAVIGATION AND TARGETING IN GPS-CHALLENGED ENVIRONMENTS USING FACTOR GRAPH OPTIMIZATION
A system and method for enhanced aircraft-based targeting senses RF emissions or other signals associated with a target while navigating a trajectory through a GPS-challenged airspace. While the target is being observed, the aircraft targeting system tracks GPS-challenged state vectors (e.g., via an onboard inertial reference system) and pressure altitudes consistent with each observation. When the aircraft emerges from the GPS-challenged airspace, the targeting system determines multiple GPS-driven subsequent absolute positions of the aircraft. The targeting system determines a refined estimate of the target location via batch factor graph optimization of measurements taken while inside and outside of the GPS-challenged airspace.
CONTROL DEVICE AND CONTROL METHOD
A positional relationship between devices that have transmitted and received signals is more accurately estimated.
A control device comprising a control section configured to perform control of estimating a positional relationship between a communication device and another communication device based on a signal transmitted and received between the communication device including at least three or more antennas, and the another communication device including at least one or more antennas, wherein the control section performs the control of estimating the positional relationship by excluding a contradictory temporary result among temporary results of the positional relationship estimated based on the signal received by the communication device from the another communication device.
ANTENNA DEVICE
A positional relationship between devices that have transmitted and received signals is more accurately estimated.
An antenna device used for an arithmetic operation that is based on a signal received from a certain communication device, the antenna device comprising a first antenna, a second antenna, and a third antenna at positions meeting respective vertices of an equilateral triangle.
Determining positional information for an object in space
The technology disclosed relates to determining positional information about an object of interest is provided. In particular, it includes, conducting scanning of a field of interest with an emission from a transmission area according to an ordered scan pattern. The emission can be received to form a signal based upon at least one salient property (e.g., intensity, amplitude, frequency, polarization, phase, or other detectable feature) of the emission varying with time at the object of interest. Synchronization information about the ordered scan pattern can be derived from a source, a second signal broadcast separately, social media share, others, or and/or combinations thereof). A correspondence between at least one characteristic of the signal and the synchronization information can be established. Positional information can be determined based at least in part upon the correspondence.
