Abstract
A system and method for reducing peak loads on a network, includes: a server in communication with a plurality of GPS receivers, the receivers sending requests for an ephemeris to the server when a time of ephemeris (TOE) for a previous ephemeris expires; and the ephemeris received by the receivers being adjusted by the addition of a value to the TOE of the ephemeris, the value being randomly adjusted to a 16 second interval between 16 seconds and 30 minutes.
