Claim:
1. A method of establishing time and/or location of a first receiver, comprising: estimating a plurality of pseudoranges based on satellite signal time delays, wherein the pseudoranges include at least one of (a) pseudoranges between the first receiver and one or more satellites estimated by the first receiver at distinct times, or (b) pseudoranges between one or more second receivers and one or more satellites estimated by the one or more second receivers, the one or more second receivers being syntonized with each other and with the first receiver; determining at least one of a time offset of a clock of the first receiver or an estimated location of the first receiver by solving a set of equations formulated based on the estimated pseudoranges; and setting at least one of a time of the clock of the first receiver or a stored location of the first receiver based on a signal reflective of the determined time offset or the estimated location, respectively.
