Navigation receiver and method for combined use of a standard RTK system and a global carrier-phase differential positioning system

A single mobile satellite navigation receiver, comprising:

• a signal receiver for receiving navigation satellite signals;
• memory;
• one or more processors;
• and
• one or more programs stored in the memory, the one or more programs comprising instructions to:
• determine a first solution of a position of the single mobile satellite navigation receiver relative to a first local positioning system, wherein the first local positioning system includes one or more reference receivers at known locations;
• determine a second solution of the position of the single mobile satellite navigation receiver relative to a wide-area differential satellite positioning system;
• and
• calculate an offset between the first solution and the second solution.

A computer readable storage medium storing one or more programs configured for execution by one or more processors in a single mobile satellite navigation receiver, the one or more programs comprising instructions to:

• determine a first solution of a position of the single mobile satellite navigation receiver relative to a first local positioning system, wherein the first local positioning system includes one or more reference receivers at known locations;
• determine a second solution of the position of the single mobile satellite navigation receiver relative to a wide-area differential satellite positioning system;
• and
• calculate an offset between the first solution and the second solution.
