We AFFIRM and REMAND.
Appellants, in the Appeal Brief3, argue the claims as a group. Pursuant to

§ 41.37(c)(1)(vii) (2006). Accordingly, all the claims stand or fall with claim 13.
Claim 13 reads as follows:
13. A method for detecting errors in GPS accuracy, comprising:
receiving GPS-related data at a marker,
calculating, from the GPS-related data, at least one derived GPS
parameter for the marker;
comparing the at least one derived GPS parameter with a
corresponding at least one expected GPS parameter; and
issuing a warning if the comparison indicates an irregularity between
any of the derived GPS parameters and any of the corresponding expected
GPS parameters;
wherein the expected GPS parameter and the derived GPS parameter
comprise at least one of: a quantity of GPS satellites received by the marker,
a set of specific satellites received by the marker, a signal-to-noise ratio
associated with a GPS satellite signal received by the marker, a carrier-to-
noise ratio associated with a GPS satellite signal received by the marker, a
satellite pseudorange determined by the marker, a rate of change of a
satellite pseudorange, the satellite pseudorange being determined by the
marker, a rate of change of a signal-to-noise ratio associated with a GPS
satellite signal received by the marker, a rate of change of a carrier-to-noise
