Claim:
A method comprising: receiving, by an assembly, sets of data on satellite signals from at least one first global navigation satellite system receiver external to the assembly at a first rate, each received set of data being associated with a particular instant of time, wherein the assembly comprises at least one second global navigation satellite system receiver; estimating, by the assembly, data for additional sets of data associated with a respective additional instant of time based on said received sets of data; providing data from said additional sets of data in addition to data from said received sets of data for a determination of a position of said at least one second global navigation satellite system receiver relative to a position of said at least one first global navigation satellite system receiver; and estimating, by the assembly, data for additional sets of data based on own sets of data, the own sets of data being determined at said first rate based on satellite signals received by said at least one second global navigation satellite system receiver.
