The present disclosure relates to a receiving device and a receiving method that can receive both signals of a GNSS signal and a wireless LAN at lower cost and more compactly. A selecting unit selects either a received GNSS signal or wireless LAN signal. By multiplying the signal selected in the selecting unit by a local oscillation signal generated in a local oscillation circuit, a converting unit converts the selected signal into an IF signal with lower intermediate frequency. A control unit controls the selecting unit, and performs control so that the GNSS signal and the wireless LAN signal are processed in a time-sharing manner in the converting unit. The technology of the present disclosure can be applied to a receiving device that receives a signal from a GPS satellite, for example.

A method for determining orientations and positions of a plurality of electronic devices is applied for at least 3 or 4 electronic devices in an area, and comprises that each electronic device obtains angle measurements, ranging measurements and positioning measurements of the electronic device; one of the at least 3 or 4 electronic devices and/or a server collects the angle measurements, the ranging measurements and the positioning measurements of each electronic device and determines an orientation and a position of each electronic device based on the collected measurements by performing a global computation.

The disclosed examples are directed to systems and methods for computing copresence of devices using GPS signals. The systems and methods access a plurality of GPS signals comprising a first set of GPS signals associated with a first device and a second set of GPS signals associated with a second device. The systems and methods align the first set of GPS signals with the second set of GPS signals and compute copresence probability for each pair of GPS signals in the aligned first and second sets of GPS signals. The systems and methods smooth the copresence probability for each pair of GPS signals and determine one or more copresence events based on the smoothed copresence probability for each pair of GPS signals.

A global, rapid acquisition, centimeter-level accuracy, high-integrity, space-based positioning service for autonomous ground vehicles, unmanned aerial vehicles (UAS), air taxis, all-weather aircraft precision landing, precision agriculture, and offshore machine control is presented. Low Earth orbit (LEO) constellations of satellites are a means to enhance medium Earth orbit (MEO) global satellite navigation systems (GNSS). An efficient spectrum broadcast underlay that enables users to access LEO carrier phase signals and their broad applications. User equipment employs coherent feed forward of the MEO GNSS ambiguous solution to recover the LEO carrier phase broadcast via robust coherent signal processing gain. Subsequently, the LEO carrier phase residuals enable rapid resolution of the unknown carrier phase biases to yield rapid acquisition of high-performance user positioning.

A satellite signal receiving device includes a sampling clock outputting circuit that receives a reference clock and outputs a sampling clock, a first RF receiving circuit that is capable of performing intermittent driving in which an on operation and an off operation, and, during the on operation, down-converts a first satellite signal received by a first receiving antenna and outputs a first intermediate signal, a first baseband processing circuit that processes the first intermediate signal in accordance with the reference clock, a second RF receiving circuit that is capable of performing intermittent driving, and, during the on operation, down-converts a second satellite signal received by a second receiving antenna and outputs a second intermediate signal, and a second baseband processing circuit that processes the second intermediate signal in accordance with the sampling clock.
