[time-nuts] Conditioning Rubidium Oscillators

[Bob Camp]

Hi

What you are looking for are survey receivers with time tag inputs and outputs. The Novatel boards are
one example of this. For about $5K you can get a nice new one with all the needed options. On the surplus 
market the Trimble NetRS shows up over a 10:1 price range, it may or may not do the job since you are looking 
for L5 and it’s L1/L2 only. For L1/L2/L5 you are looking at gear that came out in the last couple of years. That will be
expensive. L1/L2 is about the only way to go surplus. 

There are a long line of Ashtech receivers that do or do not have timing, it all depends on cables you can only see 
once you have it torn apart in your hot little hand. There are also Trimble’s successors to the 15 year old NetRS at 
various price points. 

Bob
