GNSS Radio Repeaters in Extreme Heat, a successful story
Just in case you need to survey in the desert, in the summer, with a repeater.
A customer just finished a large survey, 18 days in the field. Daily temperatures were over 115 F.
They tried my shade umbrella trick:
But the repeater would shut off midday, even with the ADL Fan cage running full tilt.
They came up with putting the repeater in a water cooler with a one gallon milk jug filled with water frozen solid:
with a notch cut for cables and the radio wire tied to the top in case water jug leaked.
The entire setup looked like this:
At the end of each long day the ice jug was still 1/2 solid.
They were broadcasting full GNSS with CMRx, 9600 baud, Satel format with no FEC if you are wondering.
File this away for the next time you have that random job in hell.
