A method, apparatus and computer readable storage medium are provided for determining whether or not GNSS navigation data are potentially manipulated. In the context of a method, GNSS reference data is received that represents one or more GNSS signals observed by a reference receiver at a reference position. The method also receives GNSS navigation data and determines, at least partially based on said GNSS reference data and the GNSS navigation data, a position estimate of said reference position. The method further includes determining, at least partially based on said reference position and the position estimate of said reference position, whether or not the GNSS navigation data are potentially manipulated.

The present disclosure is related to methods and apparatuses. According to some embodiments of the disclosure, a method includes: receiving, at a user equipment, configuration information indicating zone area information, wherein the zone area information indicates at least one geographic zone; and determining, at the user equipment, that a Global Position System (GPS) function is denied.

An automatic robot control system and methods relating thereto are described. These systems include components such as a touch screen panel (“TSP”) robot controller for controlling a TSP robot, a camera robot controller for controlling a camera robot and an audio robot controller for controlling an audio robot. The TSP robot operates inside a TSP testing subsystem, the camera robot operates inside a camera testing subsystem, and the audio robot operates inside an audio testing subsystem. Inside the audio testing subsystem, an audio signals measurement system, using a bi-directional coupling, controls the operation of the audio robot controller. In this control scheme, a test application controller is designed to control the different types of subsystem robots. Methods relating to TSP, camera, and audio robots, and their controllers, taken individually or in combination, for automatic testing of device functionalities are also described.

Disclosed in some examples are methods, systems, devices, and machine-readable mediums for providing a PNT system provided by stratospheric balloons. This stratospheric PNT system (SPNTS) replaces the space-segment of a standard PNTS with a stratospheric segment comprising one or more stratospheric balloons that provide PNTS signals usable to determine timing, positioning, and/or navigation for user devices.

In one implementation, first and second messages are received that include encoded position information for a transmitter. It is determined that both were received within some time of a previous message and that the second message was received within some time of the first message. A first location of the transmitter is determined based on the encoded position in the first message and the previously determined location. A second location of the transmitter is determined based on the encoded position in the second message and the previously determined location. It also is determined that the first and second locations are within a threshold distance. An updated second location of the transmitter is determined based on the encoded position information in the second message and the first location. A determination is made that the second location and the updated second location are within a threshold distance.

A surveying pole system comprising a surveying pole including two telescopic sections for providing length adjustability. At a first end of the surveying pole, a pointing tip is disposed for positioning on a target point of the environment. At a second end, a length reference point is disposed. The surveying pole also includes a locking mechanism for locking the length adjustability in respective lock-in positions. Each of the lock-in positions provides a corresponding distance between the pointing tip and the length reference point. A plurality of coded identifiers have a predetermined code associated with one of the lock-in positions. The surveying pole also includes a coded-identifier reader for reading the code of a respective coded identifier associated with the respective lock-in position, a communication device configured for transmitting a signal to a surveying instrument, wherein the signal is based at least on the read code.

Disclosed is route planning using a worst-case risk analysis and, if needed, a best-case risk analysis of GNSS coverage. The worst-case risk analysis identifies cuboids or 2d regions through which a vehicle can be routed with assurance that adequate GNSS coverage will be available regardless of the time of day that the vehicle travels. The best-case risk analysis identifies cuboids or 2d regions through which there is adequate coverage at some times during the day. In case path finding using the worst-case risk analysis fails, a best-case risk analysis can be requested and used to find alternate potential path(s). Time dependent forecast data that covers regions along the alternate potential path(s) can be requested and used to route vehicles, including autonomous drones, from starting points to destinations. This includes generation, distribution and use of risk analysis data, implemented as methods, systems and articles of manufacture.

An automatic vehicle positioning management system includes an on-vehicle apparatus and a portable device. The on-vehicle apparatus, installed on a vehicle, acquires a first location of the vehicle through wireless positioning. The first location is sent to the portable device which acquires a second location of the vehicle through GPS. When multiple vehicles form a fleet, each vehicle respectively sends its first and second locations to a server through its portable device. The second location of each vehicle is corrected by operations of point error analysis, image overlay and point error correction, so that the fleet can be managed more precisely.
