Abstract
A GPS utilizing redundant GPS receivers having position and time mark outputs connected directly to a processing block so that the time marks from both GPS receivers are received by the processing block and, in the event a first of the GPS receivers output becomes unusable and the system uses a second of the redundant GPS receivers while periodically checking the first for reusability, no time will be lost in the validation of the new channel.
