A navigation system using GPS, which informs the user, is used. A GPS receiver used in a navigation system using this GPS receives radio waves from three or more artificial satellites and calculates the distance between the artificial satellite and a mobile object from the arrival delay time of the radio waves, thereby moving the vehicle. It measures the position of the body.
Therefore, the radio wave transmitted by this artificial satellite includes information on the position of the artificial satellite, information on the position of another artificial satellite, information on the time at which the radio wave was transmitted, and is always transmitted. Thus, the position can always be detected even when used in a moving body.

For this reason, conventionally, data of such initial setting items is input from a keyboard before the start of measurement and GP data is input.
An information storage means such as a ROM (read only memory) in which data is stored in an internal memory of the S receiving apparatus and measured in accordance with the input data, or data of these initial setting items is recorded in advance is mounted inside the GPS receiving apparatus. The measurement is performed by using a GPS receiving device or the like.

However, in the case of the method of inputting from the keyboard, there are problems that the input is troublesome and that it takes a long time to start the measurement. In the case of the method using the information storage means, it is necessary to replace the information storage means in order to change the conditions. In the case of the replacement, it is necessary to pay attention so as not to cause electrostatic breakdown or the like. There is a problem that a plurality of information storage units having different contents of data of the initial setting items are required, so that the number of types of information storage units increases, and it is difficult to manage the types of information storage units.

Therefore, there is a need for a GPS receiver having an information storage means, which can change the data of the initial setting items by a simple operation and which can easily manage the type of the information storage means. Have been.
