Each of a first and a second navigation satellite system (NSS) are adapted
to operate according to a first and a second specification, respectively,
and each includes a first and a second plurality of space vehicles (SV),
respectively. Each of the first and the second plurality of SVs are
adapted to be identified by a first and a second plurality of unique
corresponding identifications (IDs), respectively. A processor is adapted
to receive and identify a first plurality of corresponding signals
transmitted from the first plurality of SVs in response to the first
plurality of unique corresponding IDs. The processor is adapted to
receive and identify a second plurality of corresponding signals
transmitted from the second plurality of SVs in response to the second
plurality of unique corresponding IDs. The processor is adapted to
determine position location information in response to receiving and
identifying the first plurality of corresponding signals and the second
plurality of corresponding signals.
