[time-nuts] NavSymm - Ericsson GPS Timing Receiver
I received as a gift from a friend what looks like a timing GPS antenna integrated with the receiver, with optical links for Rx and Tx (?). This the label on the box : http://dl.dropbox.com/u/15089947/NavSymm2.jpg And these are the upper and lower sides of the unit : http://dl.dropbox.com/u/15089947/NavSymm3.jpg http://dl.dropbox.com/u/15089947/NavSymm1.jpg Does anybody perhaps have a bit more information on this GPS receiver, and possibly suggest a practical use ? For example, would it be feasible to open the unit and recover maybe the 1pps signal, and some sort of data strings ?

Re: [time-nuts] NavSymm - Ericsson GPS Timing Receiver
I remember Navstar in Daventry, and have visited them a couple of times, but I think they changed their name a few years back. There are a number of references coming up on Google, relating to ex-employees. These units were obviously supplied to Ericsson, so again it might be worth trying that route. I have a couple of contacts in the UK who may be able to help.

Hello Al, I hope you and yours have a Happy New Year. I would start with the radome removal. Were those screws or pop rivets on the edges ? Hopefully our UK members can assist with documentation.

Re: [time-nuts] NavSymm - Ericsson GPS Timing Receiver
Very nice indeed with the opto isolation. I think Stans idea is reasonable. Since you have no information its worth looking under the hood as they say. See whats inside as a possible GPS engine. I suspect the optos are bolted on and you may have access to at least cmos or ttl data signals to work with. Save the optos. If you get it working thats a fine way to keep things safe and I think those are standard LCC sockets. Kind of hard to tell. If true the cables cheap on the surplus market. Regards Paul.

http://www.navsync.com/docs/mushroom_data_sheet.pdf This device looks very similar, similar name also. Pure coincidence?
