I have both South G1 , base and rover.?ÿ
What concerns I have to take about weather conditions .?ÿ
Of course avoid electric storm and or heavy rains.?ÿ
But what about?ÿ light rain , the same you can support with a rain coat, or a fog day.?ÿ
As per manufacturer it is a IP 67 device , of course I do not ever have such condition, as to drop the rover or base into water.
What about to protect both with a plastics bag ?
And what about the?ÿ dust in suspension , like we can have in a dry terrain.?
Will any of this?ÿ conditions affect the reading from satellites??ÿ?ÿ
?ÿ Hope you can help or advice me.?ÿ
Thanks in advance.?ÿ

To recap:?ÿIP67 means the unit can be dropped into a body of water up to a meter deep for half an hour, while IP68 guarantees protection in water up to 1.5m deep for the same period of time. Both are resistant to dust.

I dont know anyhting about South equipment, but Leica, Topcon, Javad and Trimble all live up their claims of weather resistance. All of these will be just fine in the heaviest of precipitation. I always worked in all weather (except lighting storms) and the only weather related problem I have had with modern GPS equipment is that the first Topcon Hiper something or other would overheat in the sun on 100?ø F days.?ÿ
Of course battery life plummets when the temperature is below?ÿ -20?ø C.?ÿ
I had a client who I was processing data for, and there was one occupation that was really noisy, wouldn't process. He told me it was a wide open point, so he asked the operator what happened. Apparently it was raining a bit hard so he held an umbrella over the receiver.
all of the receiver I have used have stood up well in the rain, except very early Trimble models (4000S), which were huge and had slots on the side for heat dissipation.?ÿ
Electric storms are a no-go for obvious reasons. High winds can be iffy, otherwise, any type of safe weather
I had a GPSonBM session that got rained on heavily.?ÿ Got thoroughly soaked picking up the gear.?ÿ That session had unusable pk-pk, probably because of the difference in weather between my receiver and the CORS.
The receiver and battery were under a plastic tub for protection.?ÿ In hot weather I put the tub sideways for shade with some air circulation around the receiver.
I would not worry about a little rain or snow.?ÿ Rain exposure is a daily for 6 moths out of the year here in the Pacific Northwet.?ÿ ?ÿ I can not begin to count the jobs I've had a base setup for days at a time in the rain.
These photos are from and landslide I worked on about a decade ago.?ÿ We had to dig the base out a couple of times a day during the winter.?ÿ By March it was mostly heavy rain in at 4000 feet in the western Cascades.
?ÿ
@aliquot With one caveat on Leica, at least. Some rain sprinkles, so I blotted the rover keyboard screen. It has been opaque ever since. Who knew?
As John Putnam said, we work in the rain in the Pacific Northwest and it has never been a problem.?ÿ
In the past when similar questions have been asked some people have recommended getting a plastic shower cap to put over the receiver. A plastic bag would work as well. If it makes you more comfortable you might try that.?ÿ ?ÿAs John Hamilton said an umbrella will block satellite signals, and one supposes that Bill's plastic tub might have done so as well. But a little plastic bag probably won't.?ÿ ?ÿ
I should have made clear that I have an antenna over the mark with nothing over it, and separate receiver on the ground that I protect from extreme conditions. Older gear.
Weather. It??s all weather or not you want to work. 😉

it was pouring rain.?ÿ
The most important thing is not to store your wet rover/base or gun in the case.
Always dry the instrument and leave the case open till it is dry.
Most instruments will have no problem with the rain but after some years it may be useful to replace some rubber gaskets.
the troposphere delay is modeled but not separately for each receiver. As long as your base and rover are experiencing similar conditions there won't be a problem.
