Remco, I've used several Jupiter 8 receivers quite successfully (in Binary Mode) with NTP & FreeBSD.
Yes, they are not really useable in NMEA mode as the second will jump around and constantly be off by 1-2sec. Are you sure your receiver has a valid almanac and enough satellites in view? Seeing the error "Navigation solution not valid" makes me think that is your problem. Most OEM receivers I've seen do not have the super-cap, so any time you power them up it is a cold-start and will require some time to settle in. Even with the super-cap I think battery life is maybe one or two days unpowered? Did you try using the DOS program "WinLabMon" to see the status of your receiver?
