摘要:
A satellite navigation system assistance server is configured to reply to client requests that include an indication of the client's location, and if an accurate location is included in the server request, the satellite navigation system assistance server computes which particular SBAS systems are observable to the requesting client, and in this case the satellite navigation system assistance server limits its replies to pertinent information for a more compact response message.

An information display device (20) is provided. The information display device includes a controller (21) for being able to execute a plurality of applications, a user interface (23) for allowing a user to instruct the controller, and a display unit (24) for simultaneously displaying an application selection menu item for allowing the user to select one of the applications and an application proprietary menu item that is used with a selected application, along with an information image created by execution of the selected application. The display unit is configured to display the information image, the application selection menu item, and the application proprietary menu at substantially the same position on a display screen of the display unit, regardless of which application is selected.
摘要:
An improved extended ephemeris navigation receiver includes a fully autonomous satellite navigation receiver for receiving microwave transmissions from orbiting navigation system satellites, and able to demodulate navigation messages that include the ephemerides for those navigation system satellites. The improvements include a force model of the accelerations acting on a particular satellite vehicle, and are exclusive to the receiver. A single observation of the ephemeris for each SV is input and propagated days into the future by integrating each SV's orbital position with its corresponding force model. The fully autonomous satellite navigation receiver thereafter has available to it extended ephemeris predictions that can be used as substitutes when said navigation messages from the respective SV cannot otherwise be immediately obtained and demodulated.

This disclosure provides a container, which includes a containing part (45), a cooling part (44) arranged outside of the containing part and for cooling by a heat absorbing action at the time of a phase transition, and a heat insulating part (41) arranged outside of the cooling part. The container may further include a holding part (42) arranged outside of the cooling part and for holding the cooling part near the containing part (45). Another cooling part (37) may be arranged outside of the heat insulating part (41), in addition to the inside of the heat insulating part. The cooling part may be a bag shaped container filled with a cooling material and may have a joined part (44a) formed by closing an opening of the container. The joined part may be configured to be exfoliated when a temperature near the cooling part reaches a predetermined temperature or more.

A high frequency circuit and radar device is disclosed. The high frequency circuit (10) includes a microstrip line (MSL), a suspended line (SML), and a connector (MTP). The MSL includes a dielectric substrate (20) having opposing first surfaces (201) and second surfaces (202), a first signal conductor (31) arranged on the first surface (201), and a ground conductor (41) arranged on the second surface (202). The SML includes a dielectric substrate (20), a second signal conductor (32) arranged on the first surface, and a metal housing (82) arranged from the second surface through a cavity (50). The MTP includes a dielectric substrate, a signal conductor (300) connecting the first signal conductor and the second signal conductor, and a metal housing arranged from the second surface through a lower cavity (53). The height H53 of the lower cavity gradually increases from the first end to the second end.
摘要:
A target object detecting device (1) is provided, which may include an acquisition part (25), a generation part (31a), and a detecting part (31b). The acquisition part (25) may acquire echo signals from target objects around a ship. The generation part (31a) may generate a first echo image based on the echo signals. The detecting part (31b) may input the first echo image into a model (41) built by machine learning, and may detect a first target object that is a target object other than a ship corresponding to the model (41), based on an output from the model.
