I found them somewhere, but now a quick search doesn't find them anywhere! :-// I must have dug them out of the Wayback Machine. Here they are. Ed P.S. Datum created the LPRO. Later, Datum was bought up by Symmetricom. |

2nd Intermediate update: GPS Antenna is on the roof - excellent receiving (min 5 sattelites, most the time 7 or 8). Reworked the 24V DC power supply for the RB Reference - changed it from a linear to a DC/DC Buck Converter (XL4015 module). System runs now a longterm test. Next (and last) step is to 3D print a nice front plate. /PeLuLe |

3rd intermediate update: After 1000 hrs non stop operation I change back from the DC/DC converter to the linear power supply. The received need ~4x cycles to get the GPS looked. Also the lock is lost time to time, when number of visible sattelites is 5 ony. Print 1st version of a front plate in white PLA. Not all holes fit perfectly (needd some manual correction). My plan is to print a 2nd version in gray ABS. /PeLuLe |
