Hi
The biggest issue I see is that the module thinks it’s in the vicinity of New
York City.
Since it’s in position hold mode, it’s not going to lock up at your location.
Next step is to watch the module dialog as it boots up. See what the CPU
on the board is doing to the module at power on.
Quite difficult to see. But it appears the gps antenna cable is just
hanging there not connected to what I presume would be a antenna.

Its definitely VC TCXO. For the tests, I disconnected GPS-FC embedded
antenna and connect it to my GPS distribution amplifier. In this case I
could have GPS signal indoor. Its not perfect. But should be enough for
troubleshooting.
I soldered TTL Serail sniffer to GPS-FC and I got

This is why antenna has disconnected on the picture. When I testing this
unit - i connecting coax to it.
Yesterday, I connected TTL serial to its Motorola Module, to see what is
going on there. Here is

Hello,
Some time ago, I got Efratom/Datum GPS-FC item. The apparatus itself
looks like good quality weather-proof aluminium case with embedded GPS
antenna. It has only one connector. That connector is using to supply
the power to the unit and as well to get 10Mhz signal from it.

Hi
If you look at the pictures you can see the oscillator they are using for the
10 MHz. At least as far as I can see
it’s markings look like those of a VC TCXO. If you mount the device outdoors
(as you must to get it to work) there
will be a lot of temperature swings. In if the little
