SETL1OFFSET
The characteristic signal delays introduced by the antenna, coaxial cable and GPSCard RF section will vary from
one system configuration to another. These delays are measurable using external test equipment. For applications
which involve very precise time transfer, or where ranges are used from multiple receivers, it may be necessary to
add an offset to the L1 pseudorange to compensate for these delays. This is equivalent to a system calibration in
that it corrects for inter-receiver range bias.
It does not affect the output position, and it is unrelated to data latencies.
NOTE: This feature is to be used by advanced users only.
Its intended application is for use in multi-card systems, in which case the clocks on the different
GPSCards must be synchronized. The command is not necessary for most applications.
