Title: Receiving apparatus
Inventor: NAKAJIMA SHUJI
IPC: G01S19/34
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a receiving apparatus which has a ease of use and can be made compact. SOLUTION: Almanac information of GPS satellites is stored in a satellite data ROM 6. At a use start point, the information is transmitted to an SRAM 7, and an operation of taking almanac data is discontinued. When data in the satellite data ROM 6 becomes invalid, a flag indicating the fact is written to a flag area 12b of an EEPROM 12 to stop the use. At the same time, fresh almanac information is taken by a GPS part 3 and stored in a satellite data memory area 12a of the EEPROM 12. The data is used thereafter. A secondary power source necessary for holding the almanac information is thus eliminated. After the receive operation by the GPS part 3 ends, electricity is supplied from a main power source to the SRAM 7 for only a predetermined time while an ephemeris is effective, and the power source is shut afterwards.
