MINIATURIZED RECEIVER FOR LOW ACCURACY TIME RECOVERY.
JOHNS HOPKINS UNIV LAUREL MD APPLIED PHYSICS LAB
This paper describes a compact receiver recently developed at the Applied Physics Laboratory. The unit is so designed as to minimize both size and cost while maintaining simple construction. The principal use of the device is in receiving accurate time information from satellites of the Navys Navigational Satellite System. The device is capable of providing accurate time information at any location in the world. It requires as a minimum only the use of the antenna which is mounted directly on the receiver case. The unit is battery operated but contains a charger for recharging the batteries when external power is available. The device provides an alert mode in which it can be left while waiting for the arrival of a satellite overhead. When this occurs, the unit emits a tone to indicate that a satellite is available for providing time information. Author
