Re: [time-nuts] ublox chip sets - what GPS device should I buy?
I think 50% is the employee discount, at least back in the day. I worked at a company that was one of the early users of Silvaco. The founder, Ivan Pesic, bought all the gear for his start up at employee discount, then started a company competing with HP TECAP. He got the network analyzer, the last bit of gear he needed, then turned in his notice. Uh, lawyers were involved eventually. ;-) -Original Message- From: David Kirkby david.kir...@onetel.net Sender: time-nuts-boun...@febo.com Date: Sat, 1 Sep 2012 08:09:07 To: Discussion of precise time and frequency measurementtime-nuts@febo.com Reply-To: Discussion of precise time and frequency measurement time-nuts@febo.com Subject: Re: [time-nuts] ublox chip sets - what GPS device should I buy?

[time-nuts] ublox chip sets - what GPS device should I buy?
I've bought an Agilent N9923A portable 2 MHz to 6 GHz vector network analyzer which supports GPS. I assumed it had the GPS bought it, but later found it it needs a GPS unit with a ublox chip set. Are there any ones to avoid, or which are good?

Re: [time-nuts] ublox chip sets - what GPS device should I buy?
Dave, that depends on which uBlox the unit supports. There are basically three different sizes: AMY, LEA, and NEO. They also sell chip-sets, but only to very large volume customers. Any of the uBlox-6 will be excellent, the choice will depend on form-factor, and also if you need a timing-version that supports position-hold mode (denoted as a -T) or not. Even the uBlox-5 units are already extremely good. This assumes you can solder the uBlox module onto a PC board inside the analyzer yourself. bye, Said In a message dated 8/31/2012 12:14:09 Pacific Daylight Time, david.kir...@onetel.net writes: I've bought an Agilent N9923A portable 2 MHz to 6 GHz vector network analyzer which supports GPS.

Some of those Microsoft hockey pucks used SIRF III chipset. I would check ebay for that kind of USB GPS.

Re: [time-nuts] ublox chip sets - what GPS device should I buy?
In my opinion it uses the NMEA sentences. For the purpose of recording position and time, the NMEA is enough and usually the GPSes receivers output by default the NMEA sentences. Of course you can't discipline anything by the USB port, so the external 10MHz is mandatory.

Re: [time-nuts] ublox chip sets - what GPS device should I buy?
These mapping programs tend to fall back to NEMA, but also have proprietary formats. (Certainly true of Garmin and Delorme.) Now I wonder if by specifying a ST USB GPS they want whatever proprietary format MS used. That is, it would have made more sense that if they wanted NEMA, they would specify NEMA. Those MS hockey pucks were notorious for being mistaken by the OS as a mouse out of the blue. You eould have to boot the notebook. All in all, a technology that didn't work well. -Original Message- From: Don Latham d...@montana.com Sender: time-nuts-boun...@febo.com Date: Fri, 31 Aug 2012 17:05:58 To: Discussion of precise time and frequency measurementtime-nuts@febo.com Reply-To: Discussion of precise time and frequency measurement time-nuts@febo.com Subject: Re: [time-nuts] ublox chip sets - what GPS device should I buy?

NOTE This feature is usable ONLY with the GPS receiver that is shipped with Microsoft “Streets and Trips” and “AutoRoute”. The GPS receiver is NOT available from Agilent. Only the GPS USB receiver is used with the FieldFox. Therefore, it is NOT necessary to purchase the very latest version of the map software. - So it seems I need to purchase Microsoft Streets and Trips with the optional GPS device, which is only $70 in total. http://www.microsoft.com/streets/en-us/default.aspx Does anyone know how good/bad that device is? I'd be using it in the UK 99% of the time.
