Abstract
A natural environment observation system has a GPS for detecting the present location (address), a calendar for providing the present date and time, a memory for storing natural phenomenon data, such as astronomical data, oceanic data, etc.; and an arithmetic unit for processing the natural phenomenon data, in accordance with the present location and time and the kind of information to be observed.
Claims16
A portable system for observing astronomical and tide-related phenomena in accordance with a present location of a user and a present date and time, comprising:
- detection means for detecting the current location of a user;
- calendar means for providing the present date and time;
- a memory for storing tide-related and astronomical data, including data for a celestial chart showing the arrangement of the constellations;
- input means responsive to an operation by the user for supplying an input signal specifying an astronomical or tide-related item to be observed;
- data selection means responsive to the input signal for selecting and loading the corresponding data from the memory;
- processor means, connected to the detection means, calendar means and data selection means, for modifying the data supplied from the memory through the data selection means in accordance with the current location of the user and the present date and time;
- and
- output means responsive to the processor means for showing the modified data.

A portable system for observing celestial and tidal information, comprising:
- detection means for detecting the current location of a user;
- calendar means for providing the present date and time;
- a memory for storing information on celestial and tidal data, said data including at least high tide and low tide times at predetermined locations and the mean number of alternations of tide at each of said predetermined locations;
- input means responsive to an operation by a user for supplying an input signal specifying celestial and tidal information to be observed;
- data selection means responsive to the input signal for selecting and loading the corresponding data from the memory;
- processor means connected to the detection means, calendar means, and data selection means, for modifying the data supplied from the memory through the data selection means in accordance with the current location of the user and the present date and time;
- and display means responsive to the processor means for displaying at least the high tide and low tide times for the user at the current location.

A system for observing astronomical information in accordance with a present location of an observer and a present date and time, comprising:
- a satellite navigation receiver for detecting the longitude, latitude, and height above sea level of the observer's present location;
- a calendar means for providing the present date and time;
- a memory for storing astronomical data including orbits of the sun, moon, planets, and constellations;
- an input means responsive to the operation of the observer for specifying astronomical information to be observed;
- an arithmetic unit programmed to process the astronomical data stored in the memory in accordance with the observer's present location, the present date and time, and the astronomical information specified by the observer;
- an information output unit for showing the specified astronomical information;
- and
- a control unit for supplying the processed astronomical data to the information output unit, wherein
- said astronomical information specified by the observer is an elevation of a celestial body, and said arithmetic unit calculates a predetermined time when the celestial body reaches the specified elevation, further comprising:
- a sound generator coupled to said control unit for generating a predetermined sound when the time provided by the calendar means coincides with said predetermined time, so that the observer may know a time when the predetermined elevation occurs, and the observer cannot miss an optimum position to see the celestial body.
