The SATNAV system is no longer operational. It takes an earth station
to upload the correct data for a 24hr period(?) to be sent from the
satellite to enable SATNAV units to correctly locate themselves. I
worked on this system for many years on commercial ships as well as
military.
I bought
Bob is loking for possible suggested uses of the satellites. I have a
suggestion (I don't know if its workable or not):
How about uploading the latest satellite keps and using the Transit sats to
update the keps for people that are located in areas where they don't have
ready access to the
Problem there is that we will never agree on the list of satellites to support.
Here's my current list:
OSCAR 3
1 01293U 65016F 10241.71079289 -.0103 +0-0 -30765-4 0 08859
2 01293 070.0765 303.6137 0020103 301.7493 058.1662 14.04801695321392
OSCAR 5
1 04321U 70008B 10241.67576056
Out of the list you posted, how many of them are usable for ham voice or
data comms?

Here's my current list:
Yes, it is 35 telemetry values conveyed as an offset of a tone
between about 2000 to 3000 KHz
I think it repeats evey 2 minutes.
Listening on 149.990MHz and aiming by hand roughly at the part
of the
sky where gpredict told me there was one, I could hear what
sounded like
a slow MFSK mode
The two in question are labelled as OSCAR 23 and OSCAR 25.
Others are labelled as NOVAs, yet others as TRANSITs.

With all this talk of the Transit satellites on 149.985MHZ, how are they
listed in the keps. I checked for other satellites of interest on
It is my understanding that the transit system is inactive.
This was a Navy navigation system that used the approx 150 MHz and
400 MHZ signals for determination of location.
I used this system while active duty in the USN submarine service.
I listened to the 149.985 MHz signal at home for many
