APPENDIX E. TROUBLESHOOTING SYNCHRONIZATION PROBLEMS 43
The GPS cards
• Time is not synchronized – check the antenna and the cable. The card should
see more than 3 satellites. Please note that when moved to a new location, the
card needs around 15 minutes to synchronize.
• The 10MHz and PPS signals are not available – check the jumpers on the card
to activate these outputs.
Other problems
• If the kernel modules can’t be loaded – probably they need to be recompiled for
the current linux kernel version.
