摘要： Provided is an information processing apparatus intended to address problems in which positioning devices simply equipped with a plurality of antennas will fail to perform the carrier positioning. The information processing apparatus includes a receiving unit and a processing unit. The receiving unit has a plurality of antennas located at second positions (Pa, Pb) and capable of receiving a carrier wave transmitted from a satellite. The processing unit performs positioning of a set first position (Po) on the basis of second phase information obtained by correcting first phase information of carrier waves respectively received by the plurality of the antennas.

摘要： A Provided is a communication device that includes a plurality of antenna units that are arranged in an array. Each of the antenna units includes a first antenna element and a second antenna element that are arranged in a first direction, a first receiving unit that receives a first wireless signal used in satellite positioning, via the first antenna element, and a second receiving unit receives a second wireless signal used in the satellite positioning, via the second antenna element. Among the antenna units, a first and a second antenna units that are positioned adjacently to each other in a second direction being perpendicular to the first direction are arranged in such a manner that the first antenna element in one of the first and the second antenna is positioned adjacently to the second antenna element in the other antenna in the second direction.

摘要： Even if a cycle slip occurs in which reception of a positioning signal is interrupted, it is not necessary to estimate an integer bias again. A position during previous observation is updated on the basis of observation information from a sensor. The position during current observation is obtained by solving a modified observation equation obtained by applying a periodic function to an observation equation including a double difference of a carrier phase observed from a positioning signal from a satellite and eliminating the integer bias with the updated position as an initial value. For example, while an error in the position updated by the first calculation unit is less than ½ of a carrier wavelength, the second calculation unit solves the modified observation equation with the updated position as the initial value.
