摘要： Apparatus for determining the present location of, or time of observation by, an observer on or in the vicinity of the Earth's surface. The apparatus provides a Satellite Positioning System (SATPS), such as GPS or GLONASS, in a portable device or card that is built to PC/104 standards. The PC/104/SATPS card (11) includes an SATPS antenna (13) to receive (and frequency downconvert, if necessary) SATPS signals (15) from one or more SATPS satellites, a microprocessor (17) programmed to receive the SATPS signals from the antenna and to perform calculations to determine the location of the antenna and/or the time of observation. The PC/104/SATPS card optionally has a buffer/translator (23, 25) to compensate for differences in SATPS signal arrival rate and signal processing rate and/or to translate signals from SATPS format to whatever format the microprocessor uses. The PC/104/SATPS card optionally has a keyboard, pen-and-tablet or other information entry means (31) and optionally has an information transfer module (29) for transferring information from the PC/104/SATPS card to another electronic apparatus for further processing or for display of the location of, or time of observation by, the antenna. Optionally, the PC/104/SATPS card also includes a display module (33) for displaying the location of, or time of observation by, the antenna in a visually perceptible manner on the card itself.
