I think a blind GPS with RS232 downlink (or RS485 with 232 converter as in the Trimble I once used at work) is *slightly* approaching overkill for this application!

I'm asking for my own future reference. Good enough to get wristwatch time. When you want the time to be correct within 100ms then it is not sufficient. There tends to be a lot of unpredictability in NMEA timing. Often you can alternatively select a manufacturer-specific protocol that performs better. But to get anywhere near the capabilities of GPS you really need a PPS signal fed to an input line that can issue interrupts. Traditionally a like like RS232 DCD is often used, but it requires a UART-interfaced RS232 port to perform well. In a Pi, a suitable GPIO input can be used. With PPS a fast system can be synchronized to well within 1us, for the Raspberry Pi it will be more like 10us.

You can see how well, or otherwise, some PPS-synced Raspberry Pi cards
are doing here:
http://www.satsignal.eu/mrtg/performance_ntp.php
Two caveats:
- all the RPi cards were updated to NTP 4.3.4 a few hours back which
will have given rise to transients.
- one or two systems (e.g. RPi #6) are sitting on the bench, and getting
sunlight directly towards them. This does no good at all for the
temperature and hence timing stability!

I was not contesting your claim, simply presenting data which I had gathered here. I did say: "how well or otherwise". It does demonstrate though that in a more temperature controlled environment a Raspberry Pi (Raspberry Pi #1) can do better than an Intel Atom system (PC Pixie) in a heated room, and perhaps have a lower offset than your 10 microsecond figure. -- Cheers, David Web: http://www.satsignal.eu

You may find that an internet source, even over Wi-Fi, provides better sync than the NMEA output of many GPS devices. It's often the last thing the internal processor generates and hence the most variable in its exact timing. -- Cheers, David Web: http://www.satsignal.eu

I'm asking for my own future reference. Depeds on what you want. If you are happy with 10s of ms jitter, it is fine, If not, it is not fine. The nmea sentences are basically sent when the system has nothing better to do (like calculate a fix). > > My example has the serial interface.

The antennas I've seen and used have all used fairly wimpy 2mm OD cable regardless of whether I bought them as add-on antennae or they came as part of an equipment package, in this case an LX RedBox FLARM and an EW Microrecorder. The latter are respectively a glider-oriented anti- collision receiver and an IGC approved flight recorder. By contrast the GPS35HV, a stand-alone blind GPS receiver which outputs NMEA 183 sentences, came with 2m of well-rubberised cable of around 5mm OD and is built like the proverbial brick outhouse. There's no contest for which one would get mounted outside: the GPS35 wins hands down for sheer ruggedness. -- martin@ | Martin Gregorie gregorie. | Essex, UK org |

This, being the most sensible and reasonable suggestion, will be
summarially rejected by the Chris Glur troll in one or more of the
following ways:
1) simply ignored;
2) an unnecessary 'wal-mart' travel required (never mind how the
troll came to obtain a rPi in the first place);
3) too much of a ballerina foo-foo answer;
4) etc.
