Re: How to use a planetary camera for occultations


 

¿ªÔÆÌåÓý

Hello all,
??? I used a module with antenna. One can also attach an aerial. It has an LED wish flashes with the PPS, albeit not very bright.
It has a PPS output on one of the pins, you could add an FET, resistor and LED to produce a brighter flash
If the signal is weak you can attach an external GPS aerial, I have one on a 5m cable
See for a suitable module
Best wishes,

Jerry

Hi all

?

Thanks for the interesting discussion.

?

Another source of 1PPS flashes are GPS dongles such as the Ublox7 et al. Cheap off the self solutions.

?

These should work with software such as NMEATime2 to bring the PC clock well within the <1sec accuracy required to know which seconds the flashes correspond to while using capture software that uses the PC clock for timestamps. All you need is a USB extension lead to use the dongle as both a flasher and a ?time source. No need for Internet for NTP.

?

Steve P, I hope to find the time to test this out prior to the next TTSO.

Cheers,

Steve R.
