Hi
At the often quoted 1.5 ns / meter error level, that would be almost 3.5 ns. At
the “worst case” 3 ns / meter
you would almost get to 7 ns.

It depends upon your lat and lon, but figure about 10 feet. Basically earth
circumference is 24,000 miles * 5280 feet per mile divided by (2**24) (bits in
the sign+significand of a 32 bit float). The math works out to 7.5 feet, but
one always has to pay some imprecise math tax...

No, the SL keyboard command on TSIP receivers should do the
"multiple-single-point-surveys-until-it-gets-close" thing to set the
lat/lon/alt to better than single precision floating point accuracy. .
The advantage of doing a full 48-hour survey is that the surveyed position was
calculated by th
Lady Heather can only talk to one device at a time, but you can fire up
multiple copies of Lady Heather to control multiple devices. You would need to
specify a different serial port to use on the second instance's command line.
Version 5.0 will let you swap serial ports and receiver type on
So need to do two long surveys then - what a pain ...
Oh well
