1. An apparatus for wireless communication at a wireless device, comprising:
a memory; and
at least one processor coupled to the memory, the at least one processor is configured to:
obtain an indication of at least one position constraint for a positioning engine;
detect whether the at least one position constraint exceeds an error threshold based on a set of pseudo-range (PR) residuals between the wireless device and at least one satellite; and
exclude the at least one position constraint from a calculation at the positioning engine if the at least one position constraint exceeds the error threshold, or include the at least one position constraint in the calculation at the positioning engine if the at least one position constraint is below the error threshold.
