[time-nuts] Trimble Resolution T versus Motorola Oncore UT+
Hi, As a new member, I have a question. I am building a Shera GPSDO and am wondering which of the Trimble Resolution T or Motorola Oncore UT+ would be a better choice. Is the Trimble software easily available, as is WinOncore? I apologize if this has been asked before, but I couldn't find the email archives. Thanks.

Software for the Resolution T is available. http://www.trimble.com/timing/resolution-t.aspx Under the tab marked 'Support' On 5/11/2013 10:28 AM, Jay Cox wrote: > Hi, > > As a new member, I have a question.

Re: [time-nuts] Trimble Resolution T versus Motorola Oncore UT+
Hi The real question is what exactly can you get for how many dollars? Old GPS cards aren't as good as the newer ones. There is a series of parts out there that are derivatives of the original Oncore's, Res-T's, and uBlox. The newer ones generally are more sensitive, track more sat's , and deliver better timing. In all cases you want the timing versions of the receivers. I believe the current "best deal" is the Oncore clone you get by calling up Synergy http://www.synergy-gps.com And mentioning Time Nuts. That's *assuming* they are still running the $39(?) deal. Bob On May 11, 2013, at 11:28 AM, Jay Cox wrote: > Hi, > > As a new member, I have a question.

I retract that! The software I have, which I downloaded months ago, is called DSPMon_V1-46.exe I do not find that on the Trimble website.

Re: [time-nuts] Trimble Resolution T versus Motorola Oncore UT+
The old Motorola Oncore UT+ is a good value. They go for $15 on ebay and have 50 nSec one sigma error on the PPS. Both newer GPSes have better specs but I wonder if it matters if you are building a Shera design GPSDO? More important than all of this is the antenna location. Make sure it has a good view of the entire sky and is far from anything that can reflect radio waves. This pretty much means it is one pipe mast of some kind.

Re: [time-nuts] Trimble Resolution T versus Motorola Oncore UT+
With the availability of Motorola Oncore products and the Synergy pin compatible it would make sense that some one does a board design that allows plug in and saw tooth correction. We use a 14 pin PIC and a DS 1023 with good results. Should also add a survey command. With the increasing cost of Tbolts this is a nice alternative. The latest Shera makes it a nice GPSDO for OCXO's and Rb's. The list price for a DS 1023 is just at $ 19 (lot of silicon) but if some one does a group buy if the interest is there a $ 25 kit price would be attainable. Right now I found a source $ 10 plus shipping I paid just over $ 6, three month ago. using one of these in a Rb application because of the long filter time may not even need saw tooth Bert Kehren In a message dated 5/11/2013 6:20:42 P.M.

Re: [time-nuts] Trimble Resolution T versus Motorola Oncore UT+
Hi They have been through a number of re-do's since the original Motorola designs. I suspect they will keep making software compatible parts as long as people keep buying enough of them for it to make sense. I'm sure that at some point the tooling cost will indeed exceed the expected revenue. Without a look at their books, no idea how long that will be….

The general idea, at least for the ones I'm familiar with, is that they will announce the end of life of a product and take orders until some date and promise to fill all those orders.

Re: [time-nuts] Trimble Resolution T versus Motorola Oncore UT+
More reasons to get it done now. There are those that thought a Tbolt at $ 100 was to expensive, same with $ 40 FEI 5680 and unlike commodity products that traditionally drop in price this is surplus at reduced price or in the case of the Synergy a one time opportunity that may go away. Try to get an I-Lotus by it self for that price and with all the Motorola documentation available what an opportunity. Bert Kehren In a message dated 5/12/2013 8:03:40 P.M.

It is not only re-tooling, a various amount of re-design can be involved. The investment to keep the product alive needs to be balanced with expected profit, such that it can be reasonably be seen that there is a profit after all the expenses have been paid off. If not sufficient profit, kill it, as it is the economical decision. Naturally, there can be side aspects which is only indirectly tied to the product, such as selling more of something you have good profit on, just because you can sell some of that product with it. So, sufficient future profit against the money you spend to keep the product alive.
