Where did you get one for $6? What make/model/brand?
That's navigation... Timing mode only needs 1 satellite lock after all,
and I suspect I will at minimum be able to get needed 1 satellite lock

Timing mode also needs special firmware. I haven't seen any of the low cost
units that come with timing mode.
Does anybody have a favorite low cost timing mode unit? How about one with
minimal soldering required?
Hal,
I see
Take care that the 1 satellite timing mode comes after having seens more
than 4 satellites for at least 1 seconds (usually, or greater). You
can't start a timing mode receiver with 1 satellite.

OK, indeed I was assuming to have the PPS with the best precision anyway.
Well, in this case I agree. Galileo? Yes, I can try with the LEA-5T. I have
to figure out how to set it so that only Galileo SVs are received. And: I

Let the GPS average the antenna position over a very long time.
On a good GPSDO one can select the number of averages, and the position
variance before the survey is finished, and the (now very precise) position
is
stored in memory.
Thanks!
Have fun experimenting

The iLotus M12M is the direct successor of the Motorola M12+ evolution of

Hi Sarah,
I've just reread the old thread from august and i don't quite
get what you are aiming for. From what i gather, you want to have

How accurate does it have to be? Sub-ms? Sub-us?
