I agree with J-P that using 'true position' instead of 'position' isn't a huge problem in the end. At my workplace when people mean 'position tolerance' they almost always use 'true position'. And even though I don't like it, I have never witnessed any miscommunication or quality issues because of that.

I've come up with Yet Another TruePosition GPSDO and I'm sharing the design files and software for it. It's a TruePosition board, controlled by an STM32 BluePill and sporting a 128x64 LCD display. Any feedback is welcome. GPSDO Selection Guide Contents • 1 Application Note Number • 2 Revision History • 3 Abstract • 4 Overview • 5 Common GPSDO Features • 6 Recommended Internal GPSDO for Each Device • 7 Sharing a Single GPSDO for Multiple USRP Devices • 8 Operating the USRP B200/B210 with Bus Power and a Board-Mounted GPSDO Building a 10Mhz GPS Disciplined Oscillator (GPSDO) using the Trimble Thunderbolt for the Ham Radio Shack. Great for Transverters, AirSpy and other devices. Building a GPSDO controller 2011 Kasper Kjeld Pedersen kkp2011@kasperkp.dk This is my work log on building yet another GPSDO The following are done: • Find a GPS receiver • Verify that the GPS receiver is sound.

Gps … Introduction: This blog post is a continuation of my two earlier GPSDO blog posts. The first one (from a few years back) details a simple Frequency-Locked Loop GPSDO design, based around an Arduino processor. The second (more recent) blog post discusses simulating Brooks Shera's GPSDO algorithm (from the July, 1998 issue of QST) using The MathWorks Simulink program. Radial True Position = .0000: Diameter True Position =.0000: If MMC adjustment is greater than deviation then MMC TP = 0.

Re: [time-nuts] TruePosition GPSDO Holdover Issues Bob kb8tq Sun, 13 May 2018 08:08:44 -0700 Hi Assuming the device has the “normal stuff” in it, it will look at the location in memory and compare that to the current solution.

This is the first part of a series, with the general description of the project, concentrating on the mechanical design. The next part will contain the electronics hardware and the third part the software component. TruePosition GPSDO 10Mhz Clock Standard Reference Distribution Board As i am working on my own GPSDO project i had multiple of these Trueposition GPSDO modules, for using them correctly i put them into enclosure.

Radial True Position = .0000: Diameter True Position =.0000: If MMC adjustment is greater than deviation then MMC TP = 0. With MMC = .0000 Finally Tim also writes that this Leo Bodnar GPSDO could just as easily be used to create a 28.8 MHz clock signal for an RTL-SDR, or any other SDR or upconverter that needs it.

In GPSDO Clock Configuration Menu untick the box Enable output 1 to avoid the GPSDO Reference Clock interfering with the VNWA internal Clock. 3. Optionally remove the RG223 Cable from the VNWA. Measurements taken with the External GPSDO clock should be similar compared to the built-in TCXO with the Pre-multiplier set to x3 .

GPSD, NTP and a GPS receiver supplying 1PPS (one pulse-per-second) output can be used to set up a high-quality NTP time server.
