Abstract

Disclosed is a system for updating a reference time from a decaying rotational period of a pulsar. The system can include: a database (DB) configured to store: coordinates for a pulsar; a recorded rate of rotation (RROR) for the pulsar; a rotational rate of decay (RROD) function for the pulsar; and a recorded reference time for the pulsar. A sensor can be configured to collect electromagnetic pulsar radiation from the pulsar and generate sensor data. A signal processor module can be configured to receive the sensor data, generate an observed rate of rotation (OROR) signal profile, generate a current rate of rotation (CROR) for the pulsar from the OROR signal profile, and update the RROR from the CROR. A time processor module can be configured to receive the RROD function and the CROR, and to solve the RROD function to output a reference time of the pulsar.
